OP-4-2THE EFFECT OF OXYGEN MASS TRANSFER INTENSITY ONBIOCATALYTIC PHENOL OXIDATION RATEBorovkova I.S., Kazakov D.A., Volhin V.V.Perm State Technical University, 614990, Perm, Komsomol pr., 29borovkova_irina_s@mail.ruPhenolic compounds are applied widely in the chemical industry and in somecases significant amounts of these compounds get to water ecosystems and causean essential damage to environment.There are many degradation methods of phenol, however most of them areineffective and have essential lacks: high cost, incomplete purification. Biocatalyticoxidation by microorganisms is one of the most effective and economically expedientmethods of wastewater treatment for phenol removal. However, for the effective useof this process for environmental biotechnology it is important to know its kinetics,which has been insufficiently studied. The phenol biooxidation proceeds in aheterogeneous system «gas-liquid-quasisolid (cell)» and includes the stage ofoxygen mass transfer from the gas phase to a liquid, which proceeds quite slowlyand can limit the rate of the process. The available literature data don’t allow toestimate the impact of this stage to the overall process rate. According to the foresaidthe aim of the research was to study the effect of gas - liquid oxygen mass transferintensity on phenol biodegradation rate.Mixed bacterial culture isolated from activated sludge of treatment facilities LLC«LUKOIL-Permnefteorgsintez» has been chosen as the object of the research. Thisbacterial culture utilizes phenol as the source of carbon and energy. Volumetric masstransfer coefficient (K L a) was used as the characteristic of oxygen mass transfer rate.It was shown that an increase of the liquid phase agitation rate resulting in K L avalue growth led to increase of phenol degradation rate. At agitation rate 600 and800 rpm average phenol degradation rate was 7.74 and 8.84 mg/(L·h) respectively,while at 1200 rpm the degradation rate rose to 10.03 mg/(L·h).Thus, obtained data show that the intensity of gas - liquid oxygen mass transfermakes essential impact on the phenol biodegradation rate. The intensification of thedegradation process can be carried out by the hydrodynamic conditions change andusing of interphase transfer activators.82
OP-4-3THE PRACTICAL APPLICATION OF MECHANICALLY ACTIVATEDENZYMATIC HYDROLYSISBychkov A.L. 1,2 , Lomovsky O.I. 11 Institute of Solid State Chemistry and Mechanochemistry, Kutateladze, 18,Novosibirsk, 630128, Russia, e-mail: bychkov.a.l@gmail.com2 Research and Education Centre «Molecular Design and Ecologically SafeTechnologies», Novosibirsk State University, Pirogova, 2, Novosibirsk, RussiaIt’s known that mannanooligosaccharides (MOS) are a perspective replacementfor antibiotics in animal husbandry [1, 2]. Modern technologies of MOS-containingpreparations production are very complicated and require big inputs. In this work theuse of mechanical activated enzymatic hydrolysis to get the antibacterial preparationcontaining mannanoproteins and mannanooligosaccharides is examined. Theprocesses effectiveness from the point of view of bioavailability ofmannanoligosaccharides for chemical and biochemical processes was estimated.The morphological changes of cell wall which take place during mechanical treatmentand enzymatic hydrolysis were studied.As a result of mechanical activation of yeast biomass the reactivity of cell wallpolysaccharides increases in relation to enzymatic hydrolysis. That effect is based oncell wall supramolecular structure disordering. Due to this the diffusion limitations arecancelled and the effectiveness of enzymatic hydrolysis of structural formingcomponent (β-glucan) increases considerably. The combination of mechanicaltreatment and further enzymatic hydrolysis allows to significantly increase (2,9 times)the bioavailability of yeast mannanoligosaccharides.The introduced approach seems perspective in the area of prophylacticantibacterial preparations production for poultry keeping. The preliminary resultswhich were achieved are the evidence of successful use of the product.References:[1]. A.E. Wold, J. Mestecky, M.
