Fat-containing wastes that are generated as a result of industrial production of food products and are being accumulated in large quantities in wastewater and sewage treatment plants and present a serious environmental problem. Microorganisms that decompose various types of lipids may be potential candidates for creation of commercial bioformulations for fat destruction. The aim of the study was to obtain pure cultures of lipophilic bacteria from fat-containing wastes, to study their diversity and activity for the development of a biological product. As a result, 30 strains of different phylogenetic groups with lipolytic activity was obtained. The most isolated strains were represented by enterobacteria and pseudomonas members within the Gammaproteobacteria. Almost half of the isolated strains were closely related to conditionally pathogenic microorganisms such as Serratia, Klebsiella etc. Non-pathogenic strains and promising for biotechnology ones belonged to Pseudomonas citronellolis, P. nitroreducens, P. synxantha, P. extremaustralis, Bacillus subtilis, B. amyloliquefaciens, Brevibacillus brevis and Microvirgula sp.
