Solid waste disposal has become a big concern all over the world. Almost 50% of the municipal waste collected daily, especially in the metropolitan cities where the population is very high, consists of organic solid waste. This organic waste left in the open dumping grounds results in stench and contamination of groundwater. The present study aims to find out the utilization of effective microbial consortia for decomposing the organic waste. Different garbage samples was collected from Panvel area for isolating the effective organic waste degrading organisms. These strains were characterized by microscopic observations and biochemical tests. Their cellulolytic, proteolytic, amylolytic and lipoolytic activities were evaluated. Depending on these enzyme activities, different consortia were prepared and their efficacy in reduction, maturity and deodorization of organic waste was compared. The plant growth promoting effect of this degraded waste on Triticum aestivum (wheat) and Zea mays (maize) was evaluated. 5 Different Microbial Consortium was developed. Microbial consortia increased the efficacy of composting as compared to control. Consortia no. 1 and 5 showed better degrading ability. Consortia 4 and 5 facilitated the best growth for Wheat and Maize respectively. Consortia 2 showed the best result in terms of germination and growth for both wheat and maize. •All the groups of consortia were effective in terms of degradation of MSW, improving the properties of soil and growth of the plants •Also, when comparing with the control, the phosphorus, nitrogen content and plant growth showed great improvements
