Abstract

The Fats, Oils and Greases (FOG) found in city waste water originate from food service centers like hotels, restaurants, street stalls, domestic kitchens etc. The disposal of FOG from such waste water present in sewer line may cause environmental bio-pollution, as the microorganisms therein are not capable of properly degrading the constituents in FOG. During present investigation, attempts were made to isolate three lipolytic bacteria i.e. Acinetobacter junii VSJK-R6, Pseudomonas composti VSJK-R8 and Pseudomonas aeruginosa VSJK-R9, from sewer line of the restaurants, and those were employed for the preparation of consortium. The consortium was then tested for the degradation of soybean, sunflower, cotton seed, ground nut and palm oils, as well as butter, which is also commonly used in kitchen . Simultaneously, a mixture of the waste water microorganisms were also tested for the same purpose. The results indicated that the consortium was superior to Waste Water Microorganisms (WWM) for degradation of oils from various sources and thus can be used for bioremediation of FOG present in kitchen waste water.
