AB  - The search for waste minimization possibilities and the valorization of by-products are key to
good management and improved sustainability in the food industry. Although dairy products
still remain at the forefront of probiotic food development, in recent years non-dairy food
products have increased in popularity owing to their unique characteristics and advantages.
Due to its beneficial properties, caused by the presence of various bioactive compounds, the
almond parts that remain after almond milk production can be considered promising sources
of ingredients for the development of non-dairy food products.
The aim of this study was to examine the potential and possibility of using a surplus product
that remains after almond milk production. The antioxidant properties of the remained surplus
product were characterized based on the polyphenol, flavonoid, and anthocyanin content as
well as FRAP, DPPH, and ABTS antioxidant activity. The fermented beverage that combines
the properties of almonds and probiotic bacteria, formulated using inulin, lyophilized fruit and
aroma, was evaluated for physicochemical, microbiological, and sensory properties during cold
storage (4 °C, 21 day).
The surplus product that remains after the almond milk production contains 61.4 mg GAE/100g
DW, 16.11 mg QE/100g DW, and 0.993 mg CYE/100g DW of polyphenols, flavonoids, and
anthocyanins (respectively), and expresses DPPH, FRAP and ABTS antioxidant activity of
71.56 mg DW/mL, 50.47 mg DW/mL and 53.11 mg DW/mL (respectively).
The fermentation of surplus product that remains after almond milk production leads to the
production of the beverage with satisfactory values of quality parameters as follows: pH value
of 4,75, titratable acidity 28,8 °SH, syneresis 7,5%, viable cell count of 7.77 log (CFU mL-1),
and sensory characteristics value of 10, that is stable during 21 day of cold storage.
A new probiotic almond-based beverage that combines the properties of both almonds and
probiotics can be considered as promising step toward the circular bioeconomy.

AB  - Microwave-assisted extraction (MAE) conditions were optimized to improve extract quality of medicinal herb — Hypericum perforatum L. (St. John’s wort) dust. Response surface methodology was applied initially to obtain the highest concentration of total polyphenols in extract solids (MAE-e). St. John’s wort was mixed with 30% ethanol in 50 mL/g solvent to solid ratio, and treated with 170 W microwave power for 40 s to yield an extract with 411.26 ± 6.21 mg GAE/g of polyphenols. This extract contained a significantly higher content of polyphenols (42.50%) and had significantly higher antioxidant activity than the macerate obtained by using European Medicines Agency (EMA) recommended procedure. The advantage of the EMA procedure was the higher yield of extract per gram of plant material. Therefore, another set of MAE conditions was defined to maximize the yield of polyphenols per gram of plant material (MAE-p). The MAE-p extract was produced by using 30% ethanol, 10 mL/g solvent to solid ratio, and 170 W microwave power for 100 s, which was, again, a markedly shorter period than 72 h of maceration. The MAE-p extract had a slightly, but significantly higher yield (5.2%), more polyphenols (8.8%), and improved antioxidant activity compared to the EMA macerate. Antimicrobial activity against several pathogens was stronger for the MAE extracts. The chemical composition of extracts was slightly different and MAE favored extraction of glycosides, in particular, rutin (quercetin-3-O-rutinoside), while the EMA macerate contained quercetin aglycon in the highest concentration. Our study demonstrates that statistically planned experiments allow for significant improvement of the extraction process, which application could facilitate better use of natural resources and deliver more potent extracts than those obtained by currently recommended procedures.

AB  - Antimicrobial properties of silver nanoparticles (Ag NPs) are well known and widely exploited. Various approaches have been applied for preparation of Ag NPs. Nowadays, „green“ methods are attracting more attention since they are eco-friendly and generally cheap. Moreover, incorporation of Ag NPs into various natural polymers enables preparation of biocompatible antimicrobial materials with controlled releasing of Ag NPs. Polymeric material also provides long term stability of Ag NPs. The aim of this study was to develop antimicrobial materials based on silver nanoparticles using green approach. Reduction of silver was performed by plant extracts of horsetail (Equisetum arvense L.) and cocoa (Theobroma cacao); the obtained nanoparticles were designated as EA Ag NPs and TC Ag NPs, respectively. The effect of extract concentration on particle size distribution and antimicrobial activity against Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus were investigated. The smallest particles with the narrowest size distribution (between 46 nm and 91 nm) were obtained with the lowest tested concentration (10% v/v) of plant extract for both horsetail and cacao. These samples also showed the highest antibacterial activities, so they were selected for preparation of nanocomposite films based on agar-agar and chitosan. It has been shown that incorporation of both EA and TC Ag NPs significantly improved antibacterial properties of the films against E. coli (≈80% higher inhibition in comparison to the pristine agar-agar/chitosan films). In the case of S. aures, TC Ag NPs incorporated in agar-agar/chitosan films enhanced inhibition of the film for 60%. On the other side, incorporation of EA Ag NPs into agar-agar/chitosan film increased the growth inhibition for only 20%. This might be due to the contribution of cocoa extract itself, i.e. some active components that inhibit the growth of S. aureus. Our results show that agar-agar/chitosan films with incorporated green synthesized Ag NPs have potential application in the areas where usage of biodegradable and biocompatible materials with high antibacterial activity is desired, such as food package, wound healing, coatings for medical devices etc.

AB  - Medicinal plants and their extracts contain substantial quantities of polyphenols. As metabolically active plant metabolites, polyphenols are food components with a wide range of biological activities. Given their poor absorbability in the digestive tract their activity toward the human host is typically mediated through interaction with intestinal microbes. As a result, polyphenols comprise a novel group of prebiotics. In this study, we tested the effect of five polyphenol-rich extracts from four medicinal herbs on the growth of probiotic and pathogenic microbes. The studied medicinal herbs were Gentiana asclepiadea L. (willow gentian), Hypericum perforatum L. (St. John's wort), Satureja montana L. (winter savory), and Achillea millefolium L. (yarrow). All these plants are traditionally used for the treatment of digestive problems. Extracts were prepared using safe solvent combinations. We tested the impact of addition of plant extracts on the growth of three probiotic lactobacilli and probiotic yeast Saccharomyces boulardii. The effect of addition of plant extracts to liquid media (concentration range 0.25-10 mg/mL) on the growth of probiotics, was tested in vitro. The antimicrobial activity of the extracts was tested against several opportunistic bacteria and yeast. St. John's wort, winter savory, and willow gentian extracts showed a stimulative effect on probiotic yeast growth, while the highest growth-stimulating effect was achieved when microwave-assisted yarrow extract was used in the concentration of 0.5 mg/mL. Under these conditions growth of S. boulardii was increased 130-fold. In addition, the yarrow extract stimulated the growth of Lactiplantibacillus plantarum 299v. The growth of two Lacticasibacillus rhamnosus strains was not stimulated by the addition of any extracts. Our results show that plant polyphenol-rich extracts can influence the growth of microorganisms that are typical members of the intestinal microbiota. For the first time we demonstrate that probiotic yeast growth can be stimulated by extracts of medicinal herbs, which when accompanied by suppression of Candida yeasts suggests a potential benefit of the treatment in diseases that are associated with fungal dysbiosis.

AB  - In this study, a spray drying process of yarrow (Achillea millefolium L.) liquid extracts was optimized by using the response surface methodology. The study aimed to determine the influence of temperature (120-195 degrees C), liquid flow rate (3-16.5 cm(3) min(-1)) and dry matter content in the liquid extract (0.3-1.5 %) on the yield of the drying process, the total polyphenols content and the antioxidant activity of the dry powder. Under the tested conditions the yield varied dramatically and ranged from 8 to 75 %, while the effects on the polyphenol content and antioxidant activity were lower. The optimized conditions for the maximum antioxidant activity and maximal yield of the dried extract were as follows: temperature of 130 degrees C, liquid flow rate of 7.5 cm(3) min(-1) and dry matter content of 1.2 %. Under the optimal conditions, the yield was 66 %, while there was a slight decrease in the polyphenol content in the dried extract as compared to that in the liquid extract (145 mg of gallic acid equivalents [GAE] per g of the total dry matter vs. 152 mg GAE g(-1), respectively). Consequently, antioxidant activity of the dry powder was only slightly reduced as compared to that of the liquid extract (DPPH neutralization was 58 vs. 64 %, respectively). The dried yarrow powder preserved its antimicrobial activity against pathogenic bacteria Staphylococcus aureus (MIC value of 10 mg cm(-3)) and Pseudomonas aeruginosa (MIC value of 20 mg cm(-3)).

This novel strain was selected out of 32 isolates based on its ability to suppress the growth of four plant pathogenic fungi: Aspergillus flavus, Fusariurn graminearum, Mucor sp. and Alternaria sp. The new marine strain was identified and characterized by phenotypic and molecular approaches. The culture filtrate of Bacillus sp. PPM3 suppressed the growth and spore germination of all tested fungi in vitro with the highest value of inhibition reported for Mucor sp. (97.5%). The antifungal effect of the culture filtrate from the strain PPM3 was due to production of highly stable secondary metabolites resistant to extreme pH, temperature and enzymatic treatments. A PCR analysis confirmed the expression of genes involved in the synthesis of antifungal lipopeptides: iturin, bacillomycin D, mycosubtilin and surfactin. In a greenhouse experiment strain PPM3 effectively reduced disease incidence of F. graminearum in maize plants and displayed additional plant growth stimulating effect. The results show that novel marine strain PPM3 could have a potential in commercial application as biocontrol agent for treatment of various plant diseases caused by soil-borne and postharvest pathogenic fungi.

AB  - Agro-industrial waste worldwide represents renewable resources (raw materials) that accumulate throughout the year. To awoid excessive accumulation of wastemore attention has been paid to the bioconversion of waste raw materials by microorganisms for obtainingthe biotechnologically valuable products. During the last few decades, enzymes mainly produced by microorganisms used in a hydrolysis process of agroindustrial waste substrates for obtaining liquid fuels are specifically requested.Bioethanol, as an alternative to petroleum based fuel, is one of the dominating renewable liquid fuels on the market. Released simple sugars by enzymatic hydrolysis of waste materials are fermented by yeast Saccharomyces cerevisiae into ethanol.
In this study, four different agroindustrial wastes: damaged rice grains, barley bran, corn meal and wastewater from transport packaging that contains starch glue were used as substrates for enzymeamylase production by P. chitinolyticus CKS1. Among them barley bran (4% barley bran, yeast extract 3g/l and casein hydrolysate 5g/l; 30 °C, 120 rpm, 48 h) showed maximum amylase production 1.65 U/ml. Enzymatic hydrolysis of different strach waste materials: damaged rice grains, barley bran, corn meal and wastewater from transport packaging using crude amylases showed that maximu reducing sugars 21.11 mg/ml were obtained using damaged rice grains. Optimal concentration of damaged rice grains for hydrolysis was10% (50 °C, 150 rpm, 120h). After enzymatic hydrolysis of damaged rice, the obtained hydrolysate was used as a substrate in fermentation process with waste brewer`s yeast S. cerevisiae(2% of inoculum).After 24 hours of fermentation at 30 °C 0.95% of ethanol was obtained.
Theresults obtained in this study showed that agro-industrial wastes could be used as substrate for enzymes production and enzymatic hydrolysis. Among tested waste materials, damaged rice grains are the most suitable for bioethanol production.

AB  - Mixed medicinal plant waste was composted with addition of novel bacterial strains belonging to the genera Streptomyces, Paenybacillus, Bacillus and Hymenobacter. The composting was followed by assessment of chemical and biological parameters including C/N ratio, loss of organic matter, phosphorous and potassium content as well as CO2 generation and dehydrogenase activity during 164 days. The selected mesophilic bacterial starters had a potential to significantly reduce the period of mixed herb waste decomposition, from about 6 months to about 2.5 months. Based on the seed germination index of four plants (Fagopirum esculentum, Thymus vulgaris, Cynara scolimus and Lavandula officinalis) the germination and radial root growth of the investigated plants was improved by the inoculated compost. The germination index of all tested species on the mature inoculated composts was in average 60% higher compared to the control compost. The research indicates that the mesophilic starter addition into the herbs waste can contribute to the speed of waste decomposition and lead to the improvement of biofertilization effect of the obtained compost.

AB  - A series of new zinc complexes containing the 2,2'-dipyridylamine (dipya) ligand and anions of four benzenepolycarboxylic (BPC) acids, namely phthalic (H(2)pht), isophthalic (H(2)ipht), terephthalic (H(2)tpht) and pyromellitic (H(4)pyr), have been synthesized by ligand exchange reactions. The complexes were characterized based on elemental analysis, FTIR spectroscopy and thermal (TG/DSC) analysis. The complexes were found to have the formulae [Zn(dipya)(pht)] (1), [Zn(dipya)(ipht)](n) (2), {[Zn(dipya)(tpht)]center dot H2O}(n) (3) and [Zn-2(dipya)(2)(pyr)] (4). Compounds 2 and 3 have been obtained as single crystals and their crystal structures were determined from X-ray diffraction data. In both structures the coordination number of the Zn atoms is five and they are linked by bridging BPC ligands. In 2, the ipht ligand is coordinated in a tridentate manner via chelate and monodentate COO groups, whereas two crystallographically different tpht ligands in 3 are coordinated as bis-chelate and bis-monodentate ligands, respectively. These combined modes of ipht and tpht anions resulted in zigzag chains of 2 and 3. Two-dimensional pseudo-layers in 2 and a three-dimensional network in 3 are governed by hydrogen bonds and C-H center dot center dot center dot O interactions which are formed between the zigzag chains, and by additional C-H center dot center dot center dot pi interactions in 3. The antimicrobial activity of complexes 1-4 was screened in vitro against some Gram-positive bacteria (Bacillus subtilis, Enterococcus faecalis, Listeria monocytogenes and Staphylococcus aureus), some Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa and Salmonella enteritidis) and yeast Candida albicans. Complex 2 showed the most potent inhibitory effect against the tested microorganisms.

AB  - Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol concentration (53-87%), liquid/solid ratio (13-47 mL/g) and microwave power (170 and 340W) was studied. The optimised conditions for the maximal recovery of polyphenols and flavonoids were as follows: 33 s of extraction time, 70% of ethanol concentration, 40 mL/g of liquid/solid ratio and 170W of microwave power. Under the optimal conditions, 237.74 +/- 2.08 mg of gallic acid equivalents per g of extract dry matter of total polyphenols, and 42.95 +/- 1.32 mg of quercetin equivalents per g of extract dry matter of total flavonoids were extracted. The optimal extract strongly reduced the diphenylpicrylhydrazyl radical (IC50 7.89 mu g/mL). The antioxidant activity of the obtained extracts was in correlation to the total polyphenol content in yarrow extracts. Compared to the conventional extractions (solid-liquid extraction (24 h) and maceration (48 h)) microwave-assisted extraction yielded extracts with higher polyphenol and flavonoid content and higher antioxidant activity in very short time (33 s).

AB  - This paper has demonstrated the valorization of inexpensive and readily available restaurant waste containing most consumed food and beverage residues as adsorbents for methylene blue dye. Coffee, tea, lettuce and citrus waste have been utilized without any pre-treatment, thus the adsorption capacities and dye removal efficiency were determined. Coffee waste showed the highest adsorbent capacity, followed by tea, lettuce and citrus waste. The dye removal was more effective as dye concentration increases from 5 up to 60 mg/L. The favorable results obtained for lettuce waste have been especially encouraged, as this material has not been commonly employed for sorption purposes. Equilibrium data fitted very well in a Freundlich isotherm model, whereas pseudo-second- order kinetic model describes the process behavior. Restaurant waste performed rapid dye removal at no cost, so it can be adopted and widely used in industries for contaminated water treatment.
AB  - Metilen plavo je bazna boja sa strukturom heterocikličnog aromatičnog jedinjenja, koja se u dobu savremenog društva često koristi za bojenje raznih tipova materijala. Efluenti iz industrije boja predstavljaju jednu od najproblematičnijih vrsta otpadnih voda za tretiranje, usled njihove velike biološke i hemijske potrebe za kiseonikom. Pored toga, toksičnost i teško razgradiva priroda boja mogu značajno uticati na fotosintetičku aktivnost vodenog sveta. Adsorpcijom na čvrstim nosačima mogu se ukloniti, odnosno, svesti na minimum razni tipovi zagađivača, zbog čega ova tehnika ima široku primenu u kontroli zagađenja voda. S tim u vezi, ispitivana je mogućnost iskorišćenja sirovog otpada iz restorana za adsorpciju i uklanjanje boje metilen plavo iz vodenih rastvora. U radu su određivani adsorpcioni kapaciteti otpadnih sirovina najčešće konzumiranih namirnica, uključujući kafu, čaj, zelenu salatu i mešavinu citrusnog voća (citrusa). Proces adsorpcije izveden je u šaržnom režimu, uz mešanje na tresilici, u uslovima ambijentalne temperature. Efikasnost procesa praćena je u zavisnosti od promene koncentracije boje u radnim rastvorima. Pokazano je da otpadna kafa ispoljava najviši adsorpcioni kapacitet, a za njom otpadni čaj, zelena salata i citrusi, redom. Nakon 30 min odigravanja reakcije, na kafi se vezalo gotovo 90%, dok na čaju 80%, zelenoj salati 60% i citrusima 30% od početne koncentracije rastvora boje. Vezivanje boje na adsorbentima bilo je efikasnije u slučajevima kada je koncentracija rastvora boje rasla od 5 do 60 mg/L. Na osnovu ispitivanja najčešće primenjivanih modela izo- termi za definisanje adsorpcione ravnoteže, pronađeno je da su ravnotežni podaci, u slučajevima svih vrsta adsorbenata, bili u skladu sa Frojndlihovom adsorpcionom izotermom. S tim u vezi, smatra se da je proces odigravanja reakcije baziran na interakcijama između molekula boje i funkcionalnih grupa na heterogenoj površini adsorbenata. Kinetika i mehanizam reakcija opisani su po principu modela pseudo-drugog reda, koji se zasniva na pretpostavci da hemisorpcija, odnosno stvaranje hemijskih veza između adsorbenta i adsorbata, kontroliše celokupan tok reakcija. Iskorišćenjem sirovog otpada iz restorana može se doći do ekonomski isplativog rešenja za brzo i efikasno uklanjanje toksičnih i teško raz- gradivih boja iz vodenih rastvora. Smatra se da ova vrsta otpadnog materijala može naći svoju primenu u brojnim adsorpcionim procesima, u prvom redu onim koji se zasnivaju na tretmanima prečišćavanja otpadnih i pijaćih voda.

AB  - Spent coffee grounds were evaluated for adsorption
efficiency in the removal of pesticide paraquat from its aqueous
solutions. The influence of the adsorbent mass, agitation time,
paraquat concentration and pH have been investigated in the batch
sorption mode. Adsorption capacity (mg/g) has been found to be
27.87 ± 1.57 mg/g, while the removal efficiency has resulted of 32.25
± 1.79 %. Adsorption rate was found to be very fast, whereby the
time required for equilibrium adsorption occurred within first 20
minutes. The process behavior was predicted using the second-order
kinetic model. On the basis of the observed data, further process
optimization may be greatly facilitated, thus it is considered that
coffee waste may be exploited well for pesticides removal purposes.

AB  - Microwave-assisted extraction was optimised by the response surface methodology in order to enhance the extraction of polyphenols from Equisetum arvense (horsetail). Under the optimal conditions the total polyphenol content in extract reached a concentration of 161.57 mg of gallic acid equivalents per g of extract dry matter. The optimal conditions were reached with 54.5% of ethanol, 45.1 mL/g liquid/solid ratio, the microwave power of 170 Wand 80s extraction time. The antioxidant activity of obtained extract was evaluated by FRAP (ferric reducing antioxidant power) and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity assay. Since, the conditions that favoured maximum polyphenol content in extract were the same as the conditions that favoured maximum antioxidant activity, the polyphenols were identified as the predominant antioxidants in horsetail extracts. When compared to the conventional extraction method (solid liquid extraction for 12 h), our results showed that more polyphenols can be extracted from waste horsetail using microwave extraction and aqueous ethanol, for just 80s. The extracts obtained by optimised extraction procedure exhibit significant antioxidant activity and can be used as a natural source of antioxidants.

AB  - Spent coffee grounds are produced during espresso coffee preparation. This waste coffee contains significant amounts of biologically valuable ingredients such as antioxidants. The effect of fermentation by Hymenobacter psychrotolerans on the antioxidant activities and total polyphenol content of the spent espresso coffee extract was determined.
Samples of spent espresso coffee were inoculated with selected natural strain of Hymenobacter psychrotolerans. The strains were cultivated on the carboxymethyl cellulose (CMC) broth and the supernatant was separated from the cells. Both supernatant and the cells suspended in saline were used for the treatment of samples. The solid state-fermentation was carried out at 30°C for five days. Solvent for extraction was water and the extracts were evaporated in the spray-dryer. The total polyphenol content was determined by the Folin-Ciocalteu method [1,2]. The antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging capacity, and Ferric Reducing Antioxidant Power (FRAP) methods [2,3]. Inhibition of DPPH radicals was expressed as IC50 value. Results were compared to those of non-fermented control sample. Fermentation of spent coffee with supernatant showed the increased content of polyphenols, while sample fermented with cells had the same amount of polyphenols compared to the control sample. IC50 values of fermented samples were lower compared to the control sample that indicates that fermented samples had higher antioxidant activity. The IC50 (μg/ml) values were 37.66, 29.00 and 18.57 for the control sample, sample treated with supernatant and fermented by cells, respectively. The FRAP assay shows that the antioxidant activity of the extract, compared to the control sample, increased only in the case of supernatant treatment, while the other extract had lower antioxidant activity. Fermentation of spent espresso coffee with Hymenobacter psychrotolerans have improved its antioxidative properties which present a potential for its application in pharmaceutical and food industry.

AB  - The importance of coffee waste utilization is based on the fact that it contains a large amount of biologically valuable components. Preparation of espresso coffee produces substantial quantities of polyphenolic acids that have a significant antioxidant activity. In this work, the contents of polyphenols and antioxidant activity of extracts obtained from spent espresso coffee were analyzed using different solvent systems. A 70% solution of methanol and a 70% solution of ethanol and distilled water were used as solvents. The total amounts of polyphenols were determined by the Folin-Ciocalteu method, while the antioxidant activities were determined by DPPH inhibition (2,2-diphenyl-1-picrylhydrazyl) and FRAP (Ferric Reducing Antioxidant Power). Both methods confirmed that the order of antioxidant activity of obtained dried extracts is as follows: water extract  lt  methanol extract  lt  ethanol extract, which was in accordance with their polyphenols content. Mild prooxidant activity was observed in the concentration of 200 μg/ml while investigating the DPPH inhibition. Prooxidant activity is a characteristic of some polypenolic acids that is considered to be one of the mechanisms of anticancer activity. The inhibition of DPPH radical, expressed by IC50 values, was compared with the results of the commercial antioxidants such are ascorbic acid and BHT (butylated hydroxytoluene). Comparing the IC50 values of ascorbic acid and BHT with the IC50 values of tested extracts it can be concluded that waste coffee extracts could be a good source of natural antioxidants.
AB  - U radu je određivan sadržaj polifenola i antioksidativna aktivnost osušenih ekstrakata otpadne espreso kafe dobijenih primenom različitih rastvarača. Kao rastvarači, u ekstrakcijama su korišćeni 70% rastvor metanola, 70% rastvor etanola i destilovana voda. Određen je ukupan sadržaj polifenola i antioksidativna aktivnost metodama inhibicije DPPH (2,2-difenil-1-pikrilhidrazil) radikala i FRAP (engl. ferric reducing antioxidant power). Inhibicija DPPH radikala je izražena preko IC50 vrednosti, a rezultati su poređeni sa rezultatima komercijalnih antioksidanata, askorbinskom kiselinom i BHT (butil-hidroksi-toluen). Obe metode su potvrdile da je redosled antioksidativne aktivnosti dobijenih suvih ekstrakta sledeći: vodeni ekstrakt  lt  metanolni ekstrakt  lt  etanolni ekstrakt. Poređenjem sa vrednostima IC50 za askorbinsku kiselinu i BHT može se zaključiti da ekstrakti otpadne kafe mogu biti dobar izvor prirodnih antioksidanata.

AB  - During espresso coffee preparation large amounts of spent coffee residues are produced and discarded daily as a part of the communal waste. However, there is a great potential in recycling this type of waste for extraction of natural antioxidants and manufacture of dietary supplements. The aim of this study was to investigate the effect of fermentation on the antioxidant properties of spent coffee extracts. Six series of spent espresso-type coffee samples were inoculated with selected natural strains of Streptomyces sp. The solid state-fermentation was carried out at 30°C five days. Aqueous extracts have been prepared and evaporated in the spray-dryer. The total polyphenol content was determined by Folin-Ciocalteu method and the antioxidant activity by two methods: inhibition DPPH (2,2-diphenyil-1-picrylhidrazyl) radicals and FRAP (Ferric Reducing Antioxidant Power). Inhibition of DPPH radicals was expressed as IC50 value. Results were compared to those of nonfermented control sample. Fermentation of spent coffee with these cultures have resulted in increased contents of polyphenols. Also, both methods have confirmed increased antioxidative activity in certain samples depending on the selected strains. It was therefore concluded that fermentation of spent coffee with Streptomyces sp. cultures have improved its antioxidative properties which presents a potential for its application in pharmaceutical and food industry.
