AB  - Viscose yarn was submitted to oxidation using different sodium periodate concentrations for various periods of time in order to investigate the influence of oxidation on the chemical and sorption properties of the resulting yarns. The oxidation progress was monitored through periodate consumption, aldehyde group content and weight loss of the modified samples. The aldehyde groups were introduced into the oxidized viscose up to 1.284 mmol/g, while the weight loss was generally of about 5%. Compared to the untreated yarn, the oxidized samples exhibited lower water retention and iodine sorption values - of 32.4% and 53.6%, respectively, while moisture sorption values decreased for an oxidation time up to 180 min and increased when the time of oxidation was longer, up to 360 min. The changes in viscose yarn wettability, because of the oxidation treatment, were evaluated based on the parameters determined by the capillary rise method, which are related to the coefficient of diffusion and radius of pores.

AB  - Cotton fibers containing different amounts of aldehyde and carboxyl groups were prepared by varying TEMPO oxidation conditions and then employed as carriers for trypsin immobilization. Depending on the functional group type present in the oxidized fiber, trypsin was immobilized through the ionic interaction or together with the Schiff's base formation. The TEMPO oxidation caused changes in the chemical and physical properties of the modified cotton, which were evaluated by determining the aldehyde and carboxyl group content, sorption and electrokinetic properties, and surface morphology of fibers. The trypsin activity was assayed with N-alpha-benzoyl- DL-arginine p-nitroanilide hydrochloride, and the protein content was determined by the Bradford method. The impact of oxidized fiber functional groups on the amount, activity and stability of the immobilized trypsin was investigated. The cotton fibers oxidized under the most severe conditions (4.84 mmol/g NaClO, 180 min) and having the highest functional groups content (0.79 mmol/g) exhibited the maximum amount of immobilized trypsin of about 6.5 mg/g. However, the immobilized activity and the stability were much higher for the fibers containing both carboxyl and aldehyde groups compared to the corresponding fibers containing only carboxyl groups.

AB  - In this study, a biologically active fibrous material was designed by immobilizing trypsin on viscose fibers. The viscose yarn was first oxidized with sodium periodate to produce aldehyde groups and then employed as a support for subsequent immobilization of trypsin through bovine serum albumin. The oxidation by sodium periodate caused changes in the chemical and physical properties of the modified yarn samples, which were evaluated by determining the aldehyde group content, fineness and tensile strength of yarn. The viscose fibers oxidized under the most severe conditions (0.4 % NaIO4, 360 min) exhibited the maximum amount of introduced aldehyde groups (1.284 mmol/g), but also the highest decrease in tensile strength. The trypsin activity was assayed with N-alpha-benzoyl-DL-arginine p-nitroanilide hydrochloride, whereas the amount of bound trypsin was determined by Bradford method. Trypsin immobilized on oxidized viscose yarn retained 97.3 and 83.8 % of the initial activity over 60 days of storage at 4 and 25 A degrees C, respectively, and remained firmly attached to the carrier. The potential application of obtained bioactive fibers is in the treatment of wounds.

AB  - The effect of periodate oxidation on the chemical and sorption properties of cotton yarn was investigated by determining aldehyde group content, moisture sorption, water retention and iodine sorption. Oxidation of cotton yarn was performed by varying concentration of sodium periodate solution and reaction time. To measure the aldehyde content present in the oxidized cotton, the aldehyde groups were selectively oxidized to carboxyl groups with sodium chlorite at pH 4-5, at room temperature for 48 h, and carboxyl group content was determined by modified calcium-acetate method. Differences in the sorption properties of untreated and oxidized cotton samples were obtained using conventional methods. The aldehyde groups were introduced into the oxidized cotton up to 99.2 μmol/g. Compared to the untreated fibers, oxidized cotton samples exhibited higher moisture sorption (up to 9%) and lower water retention values (up to 19%) and iodine sorption values (up to 31%). Based on the obtained results, it can be concluded that the crystalline structure of cellulose is not significantly changed by periodate oxidation, which is of great importance for textile material production.

AB  - Cotton yarn was first oxidized by sodium periodate to introduce aldehyde groups which were able to react with amino groups of trypsin to form Schiff's base, and result in cotton yarn immobilized trypsin. The effect of periodate oxidation on the chemical and physical properties of cotton yarn was evaluated by determining aldehyde group content, fineness and tensile strength of yarn. Measurements of protein load from Bradford assay and catalytic activity in hydrolysis of N-alpha-benzoyl-DL-arginine p-nitroanilide were made for the immobilized enzyme. The maximum amount of immobilized trypsin was 6.1 mg/g dried cotton yarn. Trypsin immobilized on oxidized cotton yarn retained 90% and 72% of the initial activity at 4 degrees C and 25 degrees C, respectively, over 60 days of storage in physiological solution.

abstract = "Cotton yarn was first oxidized by sodium periodate to introduce aldehyde groups which were able to react with amino groups of trypsin to form Schiff's base, and result in cotton yarn immobilized trypsin. The effect of periodate oxidation on the chemical and physical properties of cotton yarn was evaluated by determining aldehyde group content, fineness and tensile strength of yarn.

AB  - Today, a major concern about the use of crustacean chitin/chitosan in the pharmaceutical and biomedical field is still the molecular variability of a natural product, which results in a wide unpredictable range of physicochemical properties. Concurrently, the production of chitin/chitosan from microbial sources appears promising because the process can be manipulated to obtain a pure, rather uniform product with specific characteristics. In addition, the fermentative production of fungi on cheap industrial by-products and wastes is an unlimited and, in principle, a very economic source of chitin/chitosan. As well, the feasibility of obtaining β-glucan from the myceliar chitosanglucan complex, and the simultaneous extraction of chitin and chitosan make the microbial process more interesting (Pomeroy et al. 2001). This chapter highlights the research on microbial chitin and chitosan with a special focus on major sources and methods of their biotechnological production, as well as the difficulties in utilizing and processing them for selected applications.

AB  - The ability to produce polysaccharides is widely found among microbial species. The structural diversity of the microbial polysaccharides (MPS) leads to a wide diversity of their applications. This review focuses pharmacological properties of MPS and their derivatives. They have been reported to possess many biological activities, such as antiviral, antitumor, antimicrobial and anticoagulant activities. So, the MPS of the type beta-1,3-D-glucans, including curdlan and scleroglucan, show antitumor and antiviral activity. A number of biological and synthetic sulfated polysaccharides, including sulfated polysaccharides from marine microalgae, inhibit viral infections. Many of MPS demonstrate a series of attractive properties as carrier materials in drug delivery systems and nonviral gene delivery. Furthermore, MPS have found an application as wound-healing agents, blood plasma expanders and vaccines. Some MPS, like chitin, chitosan and alginate have an unusual combination of biological activities and physicochemical properties leading to the development of novel or improved pharmaceuticals. They have become of a great interest not only as drug and cell carriers but also as new functional materials of high biological activity, and recent progress in MPS chemistry is quite noteworthy. This review also examines the advances in the application of MPS in the field of tissue engineering.
