It is inevitable to treat the dairy waste effluents since they are the most polluting ones due to its huge volumes discharged to the inland surface water streams.The COD range of the dairy effluents is about 2000-3000 mg/L. About ten organisms of different species have been tried for finding out their ability to degrade lactose. Among the ten organisms tested three strains were found to be most promising namely K. lactis, C. laurentii and L. plantarum. The strain K. lactis,degraded all the lactose during exponential cell growth phase and removed 67% COD in shake flask cultivation.Based on the above results, a batch and continuous process was performed with K. lactis to the optimize and scale up of the biodegradation process.The present studies are carried out to evaluate the performance of various microorganisms in degrading lactose present in dairy effluent and the highly degrading strain of K.lactis was identified.
