The main organic contaminants in municipal wastewater are proteins, polysaccharides, and lipids, which must be hydrolyzed to smaller units. A high concentration of oil grease affects biological treatment processes by forming a layer on the water surface, decreased oxygen transfer rate into aerobic process. Microbial proteases, lipases, amylases, celullases should play essential roles present study aimed isolate lipase- other hydrolytic enzyme-producing microorganisms assess their degradation capabilities fat laboratory. We also evaluated microbial interactions as an approach enhance lipolytic activity. place emphasis lipase activity because not only environmental pollutants, but form undesirable tough crust pipes sewage plants. Thirty-five from were identified assessed for enzyme profiles. Lipases characterized detail quantification, chain length affinity, optimal conditions good stability isolated lipases presence chemical agents, thermal stability, wide range pH tolerance, affinity different lengths ester chains indicates that some these enzymes may candidates hydrolysis compounds wastewater. combination fermenting bacteria facilitate complete triglycerides, lingo-cellulose normally occur wastes industrial processes. This identifies mixtures capable digesting natural polymeric materials facilitating cleaning
