Isolation and Characterization of Bacteria from Laboratory Developed Activated Sludge Used in the Treatment of Food Industry Effluent.

Nowadays the developing countries are making their profit with the help of different industries. During production of various valuable products the industries also generate a large amount of waste water which may cause nuisance to the community if it is disposed improperly. Especially, marine food industrial effluent that has high oxygen demand, possibly leads to death of marine population. So by taking this problem into consideration we treated the waste by activated sludge process. The activated sludge process is totally aerobic process. In an activated sludge process aerobic and facultative microorganisms like bacteria, protozoa and rotifers, play a very important role. The isolated bacteria from activated sludge were used to treat waste. Significant reduction in the COD and BOD values were observed when isolates were used in consortium. The initaial COD and BOD values of the waste was 5440mg/lit and 2325mg/lit respectively and after the treatment with consortium for 24 hrs the COD reduced to 430 mg/lit. and BOD to 455mg/lit. So our study will be helpful to minimize the health concerning effects of the wastes generated by industries and also to keep our environment clean and healthy.
