Abstract

Microbial consortium was made for the bioremediation of distillery effluent. Consortium was made with a combination of three isolates of white rot fungus (WRF) and Pseudomonas sp and Aspergillus sp., which locally isolated from distillery effluent. Among WRF, Isolate--WR 3 produced maximum ligninolytic enzymes along with a combination of other fungal isolates. WR-3 produced maximum decolourization zone (32.0 mm) inoculated with Brillant blue dye plates within 15 days of incubation as compared with other WRF Isolates. It showed a highest lignolytic enzyme activity on 14th day in still flasks studies as compared to other WRF Isolates. The consortium of all the isolates including WRF 3 showed significantly better variations in reducing colour (85.4.%), dissolved sulphites (98.8%), sulphates (54.5%), COD (57.5%) and BOD (55.2%) respectively on 15 days of incubation compared to other isolates when used alone.

Keywords:bioremediation of distillery effluent;Pseudomonas sp;Aspergillus sp;maximum decolourization zone.
