Tannin degrading microbes isolated from tannery effluents (Klebsiella pnuemoniae MTCC 7162, Pseudomonas aeruginosa and Bacillus laterosporus MTCC 6017) were tested for their ability to degrade vegetable tannins in tannery effluents, along with other polluting parameters in the effluents like Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS). In the shake flask studies when equal-volume of effluent with media was taken at a ratio of 1: 1, Klebsiella pnuemoniae was able to bring down the load of BOD, COD, TDS and Tannin by 93%, 86%, 56% and 93% respectively in 48 hours. This was on par with the consortium of all isolates. Klebsiella pnuemoniae alone under 2L bioreactor studies was able to bring down the levels of COD, TDS and Tannin by 71%, 48% and 75% respectively, in 48 hours. Copyright © Enviromedia.
