The changes in the crystal structure of polyhydroxybutyrate, polylactide, and their blends during biodegradation under the influence of bacteria and fungi were studied using X-ray diffraction analysis. It was found that microorganisms induce structural transformations in polymers, which occur without significant mass loss of the samples. X-ray diffraction analysis revealed that biodegradation is a complex multifactorial process that depends on the nature of the polymer and microorganisms and is characterized by microstructural changes in the film samples. 

The analysis of literature sources on the prospects of cultivation and use of spelt Triticum spelta L. in biotechnological processes is carried out. Today there is considerable interest in spelt. Spelt can be an alternative raw material in alcohol production, so its microflora has been identified. The wort was obtained by thermoenzymatic treatment of grain raw materials. The microflora of spelt and wheat wort was determined.

One of the promising ways to solve the problems of environmental safety is the creation of highly efficient methods of wastewater decontamination and destruction of organic compounds in them. The electromagnetic vibration cavitator was created to treat brewing wastewater. The efficiency of vibrocavitation treatment technology for the food industry was studied. The highest degree of decontamination from biological and organic contaminants was found to be provided by the combined action of vibrocavitation and related processing of gases, nitrogen in particular.

The effect of industrially manufactured corrosion inhibitors (“G”, “K”, “L”, “M”, and “N” inhibitors) on the biological activity of thione (TB) and sulfate reducing (SRB) bacteria and corrosive microbial associations has been studied. SRB sensitivity to all the studied inhibitors has been established. The dynamics of hydrogenase reaction blocking under the action of the studied inhibitors as well as inhibition constants have been determined. Nitrogenated corrosion inhibitors are recommended to be used for protecting the subterranean metal structures from microbial corrosion.
