Chemically synthesized polymeric films are widely used for packaging in the food industry, because they are easily and inexpensively produced from uniform raw materials and are both flexible and durable. A serious disadvantage of these films is that they are not biodegradable. The growth of environmental concerns over nonbiodegradable petrochemical-based plastics raised interest in the use of biodegradable alternatives, originating from renewable sources. In this regard, the physical, chemical and mechanical properties of the biodegradable films of different composition are analyzed: gelatin-based, cornstarch and carrageenan. The films were synthesized according to the existing technologies and the following characteristics were analyzed: film thickness, mechanical properties, integral light transmission coefficient and degradation of these films in biological mediums, chemical resistance of the films and their thermal properties. Practical Applications: Through the experimental data the dependences for the prediction of physical–chemical, mechanical, optical and thermal properties of biodegradable films made of vegetable polysaccharides were obtained. The new biodegradable edible materials based on specially selected combinations of plant polysaccharides were created, which will be used in the production of edible packaging materials for foodstuffs or capsule shells for targeted delivery of biologically active substances in medicine. The detection of degradation patterns of biodegradable films based on plant polysaccharides was performed in different parts of the gastrointestinal tract, which can be used in the development of edible packaging materials for the food industry or capsule shells for targeted drug delivery in medicine. The optical behavior patterns of biodegradable edible films based on plant polysaccharides in the ultraviolet and visible regions of the spectrum were established with a view to provide subsequent creation of packaging materials for the food industry for long-term storage of products. © 2015 Wiley Periodicals, Inc.

The results of the modification of AG-OV-1 activated carbon under various conditions (by atmospheric oxygen at elevated temperatures and by hydrogen peroxide or ozone) are given. The effect of the used modifier on changes in the porosity, surface state, and adsorption capacity of activated carbon is evaluated. © Allerton Press, Inc., 2011.

The destructive modification of Magnaflok-919 high-anion polyacrylamide under the action of a microwave irradiation was studied. As a result a new, more effective flocculant was obtained, which allows valuable alimentary components (protein and edible fat) to be completely extracted from milk industry sewage. © 2010 Pleiades Publishing, Ltd.

The results of the thermal modification of AG-OV-1 and SKD-515 activated carbons under varied conditions (by atmospheric oxygen and in an atmosphere of nitrogen) are reported. It was determined that, on the thermal oxidation under selected conditions, the formation of surface oxygen compounds predominated over the process of their destruction. Upon thermal treatment in an inert atmosphere, oxygen-containing acid-type groups were removed from the surface of activated carbons or converted into pyrone (basic) and ether structures. It was shown that a change in the porous structure and the surface functional group composition of the activated carbons depends on not only the conditions of modification but also the properties of the initial carbon adsorbents. Heating in an atmosphere of air led to an increase in the adsorption of both benzene and water vapors, whereas the heat treatment of activated carbons in the inert atmosphere increased the adsorption of only the nonpolar compound (benzene). © 2015, Allerton Press, Inc.

The recombinant producer strain expressing Rhodosporidium toruloides l-phenylalanine ammonia lyase (PAL) has been obtained, and a purification procedure of PAL has been developed. The purified enzyme, PAL, has the following biochemical and catalytic characteristics: Km for l-Phe of 0.49 mM, pH optimum at 8.5, and temperature optimum at 50°C. PAL exhibited a significant cytotoxic effect toward the following cell lines: MCF7 (IC50 = 1.97 U/mL), DU145 (IC50 = 7.3 U/mL), which are comparable with E. coli l-asparaginase type-II cytotoxicity in vitro. Administration of PAL (200-400 U/kg) to L5178y-bearing mice for five times (a total dose of 1000-2000 U/kg) was well tolerated and showed the increase of life span (ILS) = 12-16%, P < 0.05. Data obtained suggest that PAL from R. toruloides has a potential for cancer treatment. © 2013 International Union of Biochemistry and Molecular Biology, Inc.

The adsorption and desorption of pyridine on the surface of granulated active carbons was studied. It was shown that pyridine was extracted from aqueous solutions because of physical adsorption and specific adsorption with the formation of H-bonds with oxygen-containing surface groups. The desorption of pyridine at temperatures up to 400°C did not cause its complete removal from the surface of adsorbents. The fraction of pyridine remaining on the surface was proportional to the amount of oxygen-containing surface groups of active carbons of the acid type. © 2011 Pleiades Publishing, Ltd.
