AB  - Colloidal stabilization of magnetic nanoparticles is one of the most important steps in the preparation of magnetic nanoparticles for potential biomedical applications. A special kind of magnetic nanoparticle are barium hexaferrite nanoplatelets (BSHF NPLs) with a hexagonal shape and a permanent magnetic moment. One strategy for the stabilization of BHF in aqueous media is to use coatings. In our research, we used an eco-friendly tannic acid, as a coating on BSHF NPLs. As-prepared BSHF NPLs coated with tannic acid were examined with transmission electron microscopy, infrared and UV-Vis spectroscopy, electro-kinetic measurements, and their room-temperature magnetic properties were measured. Stable colloids were tested in two biological complex media and antimicrobial properties of the material were examined. To enhance the antimicrobial properties of our material, we used tannic acid as a platform for the in-situ production of silver on BSHF NPLs. New hybrid material with silver also possesses magnetic properties and excellent antimicrobial activity against Escherichia coli and Staphylococcus aureus.

AB  - The main goal of this work was to optimize the method of processing wound dressing products (like gauzes, sanitary pads, cotton wool, compresses, and bandages) with a commercial silver colloidal solution (Koloid doo, Belgrade, Serbia) and then to examine the antimicrobial properties of the obtained items in order to potentially reach the market with new improved wound dressing products. The influence of different silver concentrations used for treatment on antimicrobial activity was investigated only against Escherichia coli. The antimicrobial activity of different types of materials treated with silver solutions of 30 ppm was investigated against Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis, and Enterococcus faecalis, as well as the fungus Candida albicans. The microbial reduction of the tested materials loaded with a silver solution of 30 ppm (15-20 µg of Ag on 1 g of fabric) against the Gram-negative bacteria E. coli and P. aeruginosa was almost maximal after 2 h of contact (i.e. 95 and 99 %, respectively). In the case of Gram-positive bacteria S. aureus, B. subtilis, and E. faecalis, a longer time is needed to completely eradicate bacteria (over 99 %). Antifungal activity testing against the fungus C. albicans gave moderate antifungal activity results.

AB  - Silver and titanium dioxide nanoparticles (NPs) are the most produced NPs worldwide due to their antimicrobial properties. These NPs are widely used in many fields including agriculture, where they can inhibit the growth of plant pathogens and stimulate plant growth. However, there are concerns about nanoparticles reaching the environment, as they can also manifest adverse effects. In this study, the effects of TiO2 and two types of Ag NPs (synthesized by chemical reduction and “green” by dextrane) on soil microorganisms and organic beans were investigated. Two different species of rhizospheric soil microorganisms, namely actinomycetes Streptomyces microflavus and nitrogen-fixing soil bacteria Rhizobium sp. were exposed to the low concentration of NPs. For that purpose, microorganisms were grown in nutrient media supplemented with 0.2 mM NPs. After 24 h of exposure, the numbers of viable cells of both tested microorganisms were higher in the samples compared to the controls (media without NPs) for all three NPs, suggesting their stimulatory effect on the soil microorganisms' growth. The highest positive effect was observed for Rhizobium sp. treated with TiO2 NPs (the number of viable cells increased for two orders of magnitude, from ~106 to ~108 CFU/mL). Ag NPs showed equal influence on both tested microorganisms, with dextrane-coated Ag NPs were more effective. In the experiment with organic mung beans, the same colloid solutions of Ag NPs and TiO2 NPs had a stimulating effect on the germination and root length of this plant, also. The number of germinated seeds was the same as in the control, while the average root length was higher in the samples than in the control. The average root length was 1.47 cm in the control. Seeds treated with dextrane-coated Ag NPs had an average root length even 82 % higher compared to the control. The stimulatory effect was also observed in the case of seeds treated with Ag NPs synthesized by chemical reduction and TiO2 NPs, where the average root lengths were higher for 40% and 76 %, respectively than in the control. Germination index values, which are higher than 100%, suggesting that tested nanoparticles can be used as fertilizers in agriculture. Moreover, the obtained results show that silver nanoparticles and titanium dioxide nanoparticles have a stimulatory effect on the soil bacteria and organic mung bean, which prove their safety for this kind of application.

AB  - The aim of this study was the development of a non-toxic, biosynthetic antimicrobial agent which selectively acts on only one type of microorganism, and preserves the microbiota. Antimicrobial performance of biosynthesized silver nanoparticles (Ag NPs) by horsetail (Equisetum arvense L.) extract was examined against Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus, as well as yeasts Candida albicans and Saccharomyces boulardii. Also, the cytotoxicity of Ag NPs was examined toward pre-osteoblast cells. The synthetic conditions-concentration of extract, temperature, and pH-were optimized to prepare silver colloids with different particle size distributions and long-term stability. The obtained samples were characterized using transmission electron microscopy, X-ray diffraction analysis, and absorption spectroscopy. The smaller-sized Ag NPs ( 10-20 nm), prepared at a lower temperature (20 degrees C), showed better antimicrobial performance against E. coli compared to larger ones ( 40-60 nm), prepared at high temperature (100 degrees C). On the other hand, both samples did not display any toxic action against bacteria S. aureus, or yeasts C. albicans and S. boulardii. Non-cytotoxic behavior of Ag NPs toward pre-osteoblast cells was observed for the concentrations of silver  lt = 2.25 and  lt = 4.5 mg L-1 for 10-20 and 40-60 nm-sized Ag NPs, respectively. Biosynthesized Ag NPs by horsetail extract display selective toxic action against E. coli at the ecologically acceptable concentration level.

AB  - The antibacterial ability of in situ prepared nanometer-sized silver particles, immobilized in agar-agar films, was studied as a function of the concentration of co-dopant, magnesium ions. Content of inorganic components in hybrid films was determined using inductively coupled plasma optic emission spectroscopy, and found to be low (  lt  2 wt.-%). Morphology of prepared hybrid films, studied by transmission electron microscopy, revealed the presence of non-agglomerated and randomly distributed 10-20 nm silver nanoparticles (Ag NPs) within the agar-agar matrices. Fourier-transform infrared spectroscopy indicated the distinct chemical interaction between Ag NPs and polymer chains. Thermogravimetric analysis, as well as the determination of tensile strength, Young's modulus, and elongation at break showed improvement of thermal stability and mechanical properties of agar-agar matrices upon the incorporation of Ag NPs due to high compatibility between the hydrophilic organic component and inorganic components. The complete microbial reduction of Gram-positive bacteria Staphylococcus aureus was observed for all agar-silver films, while satisfactory results were observed for Gram-negative bacteria Pseudomonas aeruginosa (  gt = 99.6%). The release of Ag+ ions is suppressed by the increase of the concentration of Mg2+ ions and it was found to be significantly smaller (  lt = 0.24 ppm) than the harmful ecological level (1 ppm).

AB  - The visible-light-responsive inorganic-organic hybrid was prepared by surface modification of commercial TiO2 powder (Degussa P25) with 4-chlorophenol (4-CP). The optical absorption of the hybrid material is red-shifted compared to unmodified TiO2 powder due to the surface charge transfer complex (CTC) formation. The experimental results are supported by the density functional theory (DFT) calculations of the corresponding model cluster. The calculated electronic excitation spectrum is in agreement with the measured reflection spectrum of surface-modified TiO2 powder with 4-CP. The paramagnetic species, generated in the unmodified and surface modified TiO2 powders upon excitation with ultraviolet and visible light, were identified using low-temperature electron paramagnetic resonance (EPR) spectroscopy. The formation of trapped electrons (Ti(III) centers) and the persistent oxygen-centered organic radicals indicated the photoinduced electron transfer from the chemisorbed 4-chlorophenol to the conduction band of TiO2.

AB  - Antibacterial and antifungal ability of silver nanoparticles (Ag NPs) supported by functionalized magnetite (Fe3O4) with 5-aminosalicylic acid (5-ASA) was tested against Gram-negative bacteria Escherichia coli, Gram-positive bacteria Staphylococcus aureus and yeast Candida albicans. Characterization of materials including transmission electron microscopy, X-ray diffraction analysis, and inductively coupled plasma optic emission spectroscopy technique followed each step during the course of nanocomposite preparation. The synthesized powder consists of 30-50nm in size silver particles surrounded by clusters of smaller (approximate to 10nm) Fe3O4 particles. The content of silver in the nanocomposite powder was found to be slightly above 40 wt.-%. Concentration-dependent and time-dependent bacterial reduction measurements in dark indicated that use of Ag NPs leads to the complete reduction of E. coli and S. aureus even at the concentration level of silver as low as 40 g/mL. However, the negligible antifungal ability of synthesized nanocomposite was found against yeast C. albicans in the entire investigated concentration range (0.1-2.0mg/mL of the nanocomposite, i.e., 40-800 g/mL of silver). Complete inactivation of E. coli and S. aureus was achieved in five repeated cycles indicated that synthesized nanocomposite can perform under long-run working conditions. From the technological point of view, magnetic separation is the additional advantage of synthesized nanocomposite for potential use as an antibacterial agent.

AB  - The TiO2 based hybrid supports with different functional groups (amino, glutaraldehyde or epoxy) were prepared and their influence on immobilization of dextransucrase (DS) was studied. Novel synthetic route for surface modification of TiO2 with amino and glutaraldehyde groups was developed taking advantage of charge transfer complex (CTC) formation between surface Ti atoms and salicylate-type of ligand (5 aminosalicylic acid (5-ASA)). The proposed coordination of 5-ASA to the surface of TiO2 powder and optical properties of CTC was presented. The pristine TiO2 and amino functionalized TiO2 have higher sorption capacity for DS (12.6 and 12.0 mg g(-1), respectively) compared to glutaraldehyde and epoxy activated supports (9.6 and 9.8 mg g(-1) respectively). However, immobilized enzyme to either glutaraldehyde or epoxy functionalized TiO2 have almost two times higher expressed activities compared to pristine TiO2 support (258, 235 and 142 IU g(-1), respectively). Thermal stability of enzyme immobilized on glutaraldehyde and epoxy functionalized supports was studied at 40 degrees C, as well as operational stability under long-run working conditions in repeated cycles. After five cycles, DS imobilized on glutaraldehyde activated support retained almost 70% of its initial expressed activity, while, after five cycles, performance of DS immobilized on epoxy activated support was significantly lower (15%).

AB  - Amylases are industrially important enzymes which could convert starch to glucose, maltose and oligosaccharides. A bacterial strain designated as Paenibacillus chitinolyticus CKS1which was isolated from the soil of the coniferous forest, produced β-amylases using different commercial and waste substrates. Maximum β-amylases activity of 0.820 U/mL was obtained using a sugar alcohol-isomaltidex (0.5% w/v), as a substrate for microorganism growth and enzyme production. After 48 h of fermentation in a medium that contained starch (0.5%, w/v) and 0.05% v/v of ethanol, CKS1 produced β-amylase with the activity of 0.518 U/mL. The latest trends in enzyme production include utilisation of various waste products, mainly of agroindustrial origin, as a substrate for microorganisms growth. The strain CKS1 was also able to grow and produce β-amylases by using plant waste material. The plant waste substrate (PWS) contained plant biomass that is left after the ethanol extraction of various medicinal herbs (marigold and chamomile flowers, artichoke leaf, lemon balm leaf, nettle leaf, thyme leaf, yarrow shoot, yellow gentian shoot, primrose shoot, valerian shoot and chestnut and hawthorn seeds).This mixture of dried plant biomass is dissposed as such as a waste. In a medium with 0.1% (w/v) of PWS, CKS1 produced β-amylases with a maximum activity of 0.569 U/mL. The results show the potential of utilising waste plant biomass, left after ethanol extraction of medicinal herbs, in production of amylases. The application of microorganisms in β-amylase production using waste substrate is economically and environmentally accepted.

Najnoviji trendovi u proizvodnji enzima odnose se na korišćenje različitih otpadnih sirovina agroindustrijskog porekla kao supstrata za rast mikroorganizma.

Ova biljna biomasa, iz koje su ekstrahovane bioaktivne materije, meša se i odlaže kao takva u vidu otpada. Nakon rasta u podlozi sa 1,0 % (w/v) PWS, soj CKS1 proizveo je β-amilaze sa aktivnošću od 0,569 U/mL. Ovi reziltati ukazuju na mogućnost iskorišćenja otpadne biljne biomase, zaostale nakon alkoholne ekstrakcije lekovitog bilja, u procesima ekonomičnije proizvodnje amilaza. Korišćenje otpadne sirovine u mikrobnim procesima proizvodnje enzima je i ekološki mnogo prihvatljivije usled uticaja na smanjene skladištenja otpada a samim tim i sveukupnog zagađenje životne sredine.

AB  - The agricultural raw industry generates large amounts of annually by-products that create disposal problems. Hitherto, there have been no reported papers about the simultaneous production of cellulase and beta-amylase from these raw materials using Paenibacillus sp. that would reduce the costs. Thus, in this paper simultaneous cellulase (CMC-ase and avicelase) and beta-amylase production using barley bran and the application of the natural isolate Paenibacillus chitinolyticus CKS1 and potential enzymes in the hydrolysis process was studied. Response surface methodology was used to obtain the maximum enzyme activity (CMC-ase 0.405 U mL(-1), avicelase 0.433 U mL(-1) and beta-amylase 1.594U mL(-1)). Scanning electron microscopy showed degradation of the lignocellulosic-starch structure of barley bran after fermentation. The CKS1 bacterial supernatant, which contains cellulases and beta-amylase, could hydrolyze cotton fibres and barley bran, respectively. The main products after enzymatic hydrolysis of cotton fibres and barley bran, glucose (0.117 (-1)(g gmat)) and maltose (0.347 (-1)(g gmat)), were quantified by high performance liquid chromatography (HPLC). The produced enzymes could be used for hydrolysis of cotton fabric and barley bran to glucose and maltose, respectively. Application of simultaneous enzymes production using an agricultural by-product is economically and environmentally accepted and moreover, valuable biotechnological products, such as glucose and maltose, were obtained in this investigation.

The produced enzymes could be used for hydrolysis of cotton fabric and barley bran to glucose and maltose, respectively. Application of simultaneous enzymes production using an agricultural by-product is economically and environmentally accepted and moreover, valuable biotechnological products, such as glucose and maltose, were obtained in this investigation.",

AB  - A simple, fast and non-costly method for selective cysteine (Cys) detection, based on optical changes of silver colloids, is developed. For that purpose, stable colloids consisting of silver nanoparticles (Ag NPs) coated with polysaccharide dextran (Dex), isolated from bacterium species Leuconostoc mesenteroides T3, were prepared. The synthesized samples were thoroughly characterized including absorption and FTIR spectroscopy, as well as transmission electron microscopy and X-ray diffraction analysis. The silver colloids display high sensitivity and selectivity towards Cys detection in aqueous solutions. The Ag NPs coated with Dex provide possibility to detect Cys among a dozen amino acids and its detection limit was found to be 12.0 M. The sensing mechanism - red shift of optical absorption - is discussed in terms of the agglomeration of Ag NPs due to formation of hydrogen bonds between Cys molecules attached to different Ag NPs.

AB  - This study highlights the potential of cotton fabric as a promising feedstock for the production of bioethanol as renewable biofuel. The effect of corona pre-treatment of non-mercerized and mercerized cotton fabrics on glucose and ethanol yield is discussed. Fermentation kinetics for ethanol production and the basic process parameters were assessed and compared. Corona pre-treatment of cotton fabrics led to an increase in the glucose yield (compared to control sample) during enzymatic hydrolysis, and consequently the ethanol yield during fermentation by yeast Saccharomyces cerevisiae var. ellipsoideus. The system with mercerized cotton fabric was found to be superior obtaining an ethanol productivity of 0.900 g/Lh and ethanol yield of 0.94 g/g (based on glucose) after 6 h of fermentation time. The similar results were obtained during processing of waste cotton materials performed under the same process conditions. The obtained results showed that cotton fabric could become an alternative feedstock for the bioethanol production. For potential industrial implementation the waste mercerized cotton scraps would be the materials of choice.

AB  - This study was aimed to elucidate the biodegradation behaviour of cotton and cotton/PET fabrics 
impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behaviour was assessed according to 
standard test method ASTM 5988-03 and soil burial test, where the extent of biodegradation was 
estimated by the calculation of fabric weight loss. The morphology of fibres affected by biodegradation 
was analysed by SEM. 
The results indicated that Ag/TiO2 nanoparticles inhibit the biodegradation of investigated cotton and 
cotton/PET fabrics. As expected, biodegradation of cotton fabric was considerably more pronounced 
compared to cotton/PET fabric. Larger inhibition of biodegradation of cotton fabrics impregnated with 
Ag/TiO2 nanoparticles compared to impregnated cotton/PET fabrics was not only due to the poor 
biodegradability of PET, but also because of significantly larger content of Ag in the cotton fabric. 
Severe damage of cotton fibres during the biodegradation process was also confirmed by SEM.

AB  - Recently, many efforts have been made to efficiently impregnate different textile materials with metal and metal oxide nanoparticles in order to provide antimicrobial, UV protective or self-cleaning properties. Evidence of their environmental risks is limited at this point. The aim of this study was to explore the influence of Ag and TiO2 nanoparticles on biodegradation of cotton fabrics. Biodegradation behavior of cotton fabrics impregnated with Ag and TiO2 NPs from colloidal solutions of different concentrations was assessed according to standard test method ASTM 5988-03 and soil burial test. Degradation of cotton fabrics was also evaluated by enzymatic hydrolysis with cellulase. The morphology of fibers affected by biodegradation was analyzed by scanning electron microscopy (SEM). In order to get better insight into biodegradation process, dehydrogenase activity of soil has been determined. Ag and particularly TiO2 nanoparticles suppressed the biodegradation of cotton fabrics. The dehydrogenase activity of soil with cotton fabrics impregnated with TiO2 nanoparticles was the weakest. Severe damage of cotton fibers during the biodegradation process was confirmed by SEM.

AB  - The possibility of in situ photoreduction of Ag+ using colloidal TiO2 nanoparticles deposited on the surface of polyamide fabric in the presence of the amino acid alanine and methanol is discussed. The presence of TiO2/Ag nanoparticles on the polyamide fabric was confirmed by FESEM and ICP analyses. The antibacterial activity of the fabric was tested against the Gram-negative bacterium Escherichia coli and the Gram- positive bacterium Staphylococcus aureus. The TiO2/Ag nanoparticles fabricated on the surface of the polyamide fabric provided maximum bacterial reduction and thus, excellent antibacterial activity. In spite of silver leaching from the fabric during washing, the impregnated polyamide fabric preserved the maximum reduction of E. coli colonies. The antibacterial activity against S. aureus was slightly decreased after ten washing cycles, but still the antibacterial activity could be considered as satisfactory. In addition, the presence of TiO2/Ag nanoparticles ensured better UV protection efficiency, which belonged to the UV protection category very good.

AB  - This study was aimed to highlight the possibility of cotton fabric impregnation with silver nanoparticles synthesized by dextran isolated from Leuconostoc mesenteroides T3 in order to obtain antimicrobial properties. The fabrication of dextran was proved by FTIR spectroscopy. Particle sizes of synthesized dextran and silver nanoparticles were measured by dynamic light scattering method. The presence of silver nanoparticles on the surface of cotton fabric was confirmed by scanning electron microscopy, X-ray diffraction measurements and reflectance spectrophotometry. Antimicrobial activity of cotton fabric impregnated with silver nanoparticles was tested against bacteria Escherichia coli and Staphylococcus aureus, and fungus Candida albicans. The results indicated that synthesized silver nanoparticles can provide satisfactory antimicrobial activity. However, maximum reduction (99.9%) of all tested microorganisms can be obtained only when 1.0 mmol L-1 colloid consisting of silver nanoparticles is applied.

The presence of silver nanoparticles on the surface of cotton fabric was confirmed by scanning electron microscopy, X-ray diffraction measurements and reflectance spectrophotometry. Antimicrobial activity of cotton fabric impregnated with silver nanoparticles was tested against bacteria Escherichia coli and Staphylococcus aureus, and fungus Candida albicans. The results indicated that synthesized silver nanoparticles can provide satisfactory antimicrobial activity. However, maximum reduction (99.9%) of all tested microorganisms can be obtained only when 1.0 mmol L-1 colloid consisting of silver nanoparticles is applied.",

AB  - The possibility of in situ photoreduction of Ag+-ions using TiO2 nanoparticles deposited on cotton and cotton/PET fabrics in the presence of amino acid alanine and methyl alcohol has been discussed. The possible interaction between TiO2, alanine and Ag+-ions was evaluated by FTIR analysis. The fabrication of TiO2/Ag nanoparticles on both fabrics was confirmed by SEM, EDX, XRD, XPS and AAS analyses. Cotton and cotton/PET fabrics impregnated with TiO2/Ag nanoparticles provided maximum reduction of Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus. Although excellent antibacterial activity was preserved after ten washing cycles, a significant amount of silver leached out from the fabrics into the washing bath. The perspiration fastness assessment revealed that smaller amounts of silver were also released from the fabrics into artificial sweat at pH 5.50 and 8.00. In addition, deposited TiO2/Ag nanoparticles imparted maximum UV protection to fabrics.

AB  - The effect of cotton fabric pretreatment with biopolymer chitosan (CHT) on deposition of colloidal triangular silver nanoplates was studied. Also, the influence of deposited silver nanoparticles on color and antimicrobial activity of cotton fabrics was evaluated. Characterization of colloidal silver nanoparticles as well as silver nanoparticles deposited on cotton fabrics was performed using electron microscopy (TEM and FESEM), XRD analysis, atomic absorption spectroscopy, UV-Vis absorption, and reflectance spectroscopy. The cotton fabric turned from white to blue color upon deposition of triangular silver nanoplates. Antimicrobial activity of CHT pretreated cotton fabric impregnated with silver nanoparticles was tested against Gram-negative bacteria Escherichia coli, Gram-positive bacteria Staphylococcus aureus, and fungi Candida albicans. Deposited silver nanoparticles imparted excellent antimicrobial properties to cotton fabric. The standard sterilization procedure of cotton fabric for antimicrobial activity testing resulted in color change of the fabric from blue to yellow. This color change is most likely consequence of transformation of triangular silver nanoplates into nanodiscs and/or their agglomeration into spheroids.

AB  - Antibacterial and calorimetric evaluation of cotton fabrics dyed with direct dyes and loaded with Ag nanoparticles This study discusses the relationship between loading of cotton fabric with colloidal Ag nanoparticles and dyeing with direct dyes - C.I. Direct Yellow 86, C.I. Direct Red 79 and C.I. Direct Blue 78. The influence of order of Ag nanoparticles loading and dyeing of cotton fabrics as well as the concentration of applied dye on their antibacterial activity and colour change were studied. Antibacterial activity was tested against gram-negative bacterium E. coli and Gram-positive bacterium S. aureus. Dyed cotton fabrics loaded with Ag nanoparticles exhibited excellent antibacterial properties independently of dye concentration and order of dyeing and loading of Ag nanoparticles. Colour change of cotton fabrics due to presence of Ag nanoparticles is highly influenced by the order of operations, applied dye and dye concentration. The stability of these nanocomposite textile materials was tested in acidic and alkaline artificial sweat. The release of silver occurred independently of the pH value of the sweat.

AB  - The potential application of low-temperature radio frequency (RF) plasma for fiber surface activation in order to enhance the binding efficiency of colloidal silver nanoparticles onto the polyester fabrics and improve the stability of antibacterial effects was studied. Antibacterial activity and laundering durability were tested against gram-negative bacterium Escherichia coli and gram-positive bacterium Staphylococcus aureus. Plasma treatment positively affected the loading of silver nanoparticles as well as antibacterial activity and laundering durability of these textile nanocomposite materials. In spite of good laundering durability after five washing cycles, it was found that silver leached from the fabric into the bath during washing. Released silver from the washing effluent was efficiently removed by recycled wool-based nonwoven sorbent modified with hydrogen peroxide and biopolymer alginate.

AB  - In this study, the influence of dyeing on the antibacterial efficiency of polyamide and polyester fabrics loaded with colloidal Ag nanoparticles and the influence of the presence of Ag nanoparticles on the color change of dyed fabrics were investigated. Dyes C.I. acid green 25 and C.I. disperse blue 3 were used for dyeing of polyamide fabrics, while dye C.I. disperse violet 8 was used for dyeing of polyester fabrics. The influence of Ag nanoparticles on the color change of polyamide fabrics depends on the dye type, but generally it was lower compared to polyester fabrics. Polyester fabrics exhibited excellent antibacterial efficiency against Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Escherichia coli, independent of the order of dyeing and Ag loading. Polyamide fabrics provided a desirable level of antibacterial activity only if the Ag loading was performed after dyeing.

AB  - The aim of this study was to examine the influence of dyeing on antibacterial efficiency of corona activated polyamide and polyester fabrics loaded with colloidal Ag nanoparticles as well as the influence of the presence of Ag nanoparticles on the color change of dyed fabrics. C.I. Acid Green 25 and C.I. Disperse Blue 3 were used for dyeing of polyamide fabrics and C.I. disperse violet 8 for polyester fabrics. The color change of polyamide fabrics depends on the dye type, which was generally lower compared to polyester fabrics. Antibacterial efficiency of Ag loaded fabrics was tested against Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Escherichia coli. Corona activated polyester and polyamide fabrics showed excellent antibacterial efficiency independently of order of dyeing and Ag loading. The morphology of fibers loaded with Ag nanoparticles was assessed by SEM and atomic absorption spectroscopy for elemental analysis.

AB  - Purpose - The purpose of this paper is to investigate the possible application of recycled wool-based nonwoven material (RWNM) for removal of different dyes that are used in textile dye houses. Design/methodology/approach - The sorption kinetics, the influence of initial dye concentration, pH and temperature are analyzed. Basic, reactive, direct and metal complex dyes are studied. Findings - The sorption properties are highly influenced by the type of the dye owing to differences in their chemical structure and thus, the mechanism of binding to wool. Modification of material with chitosan and hydrogen peroxide improves the sorption capacities and sorption rates but no general trend can be established. Consequently, the sorption behaviour is analyzed separately for each type of the dye. Originality/value - The results indicate that RWNM can be used as an efficient, low-cost Sorbent for decolorisation of effluents.
