ABSTRACT

Effluent originating from distilleries which contain large amount of dark brown colored wastewater called Molasses Spent Wash (MSW). Dark brown colour of MSW is due to the presence of Melanoidin pigment. It generally produced by ‘Millard’ reaction and it is recalcitrant polymer. If dispose to untreated posses a great threat to environment. Melanodin was degraded or decolourise by using different microbial species. Microbial decolourization and degradation on the basis of (COD) chemical oxygen demand and spectrophotometer analysis were found to be dependent on the specific carbon and nitrogen source. The collection of indigenous bacterial cultures was performed to estimate its ability to degrade harmful pollutants present in molasses spent wash (MSW) and to understand its degradation potential through natural attenuation for which different bacterial species (Pseudomonas aeruginosa, Proteus vulgaris, Two Bacillus isolates) was utilized. From the following results 1.2% glucose/peptone concentrations were considered to be the optimized source for carbon and nitrogen for the organisms. Further, the degradation potential of the consortia (Pseudomonas aeruginosa, Proteus vulgaris, and Two Bacillus isolates) in different concentrations of MSW along with its application on potted Soyabean plant was studied.
