Abstract: Among all the wastes, disposal of large amount of food waste is one of the most serious problems in cities. As food waste has high water content and decomposes readily, many unpleasant environmental consequences can arise during its storage, collection and transportation. The bioconversion of solid wastes into compost by microbial population can be proved as an efficient, ecofriendly, and cost effective solution for the management of solid wastes. The objective of this study was to evaluate in vitro compatibility of different microorganisms and to study the effect of successive microbial population on solid wastes for its successful bioconversion into compost. The most promising strategies for improving management of solid wastes have been identified as minimization of the amount of the solid. The composting process involves the controlled aerobic exothermic microbial decomposition. Saccharomyces cereviseae, Trichoderma viridae and Bacillus (PU7), accession number GU566359, isolated from rhizosphere of Sesbania grandiflora from Mahabubnagar (16.4600° N, 77.5600° E), India, were selected for compatible/incompatible mixed cultures. Combinations of them were used to evaluate their potential performance as compatible/incompatible culture for microbial decomposition.

Keywords: Invitro compatibility, bioconversion, solid waste and microorganisms
