ABSTRACT
Biological treatment of waste waters is a sustainable alternative for waste treatment to existing treatment methods. Microbial metabolism effects pH, BOD, COD, DO and concentration of suspended solids present in slaughter house waste water. Rhodobacter sp. GSKRLMBKU-02 from paper mill waste water was used in the present study to remediate slaughter house waste water. Treatment with this bacterium caused a significant decrease in some of the parameters tested for waste water. Remediation of slaughter house waste water of Warangal by Rhodobacter sp. GSKRLMBKU-02 showed a 28% decrease in DO, 52% decrease in BOD, 76% decrease in COD and organic matter decreased to the extent of 55%. Further a reduction in the levels of Chloride (68%), sulphates (69%) and bicarbonates (34%) were also noticed due to the growth of this bacterium.
