NOVELTY - Microbial composition comprises (in vol.%): starch degrading bacteria (15-25), oil degrading bacteria (10-25), protein degrading bacteria (15-30) and cellulose degrading bacteria (10-25).    USE - The microbial composition is used in anaerobic fermentation of kitchen/food waste for degradation of the kitchen/food waste for producing methane (claimed).    ADVANTAGE - The microbial composition enables effective degradation of the kitchen waste. The microbial composition accelerates fermentation process of the kitchen/food waste, and improves or enhances yield of biogas i.e. methane, as the composition comprises synergistic effect of various microorganisms.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing the above-mentioned microbial composition, which involves (a) screening the starch degrading bacteria, oil degrading bacteria, protein degrading bacteria and cellulose degrading bacteria from sample, (b) culturing and purifying the above-mentioned bacteria, and screening high quality starch degrading bacteria, oil degrading bacteria, protein degrading bacteria and cellulose degrading bacteria from each of obtained bacterial colony to obtain seed liquid, (c) inoculating (1%, each): starch degrading bacteria, oil degrading bacteria, protein degrading bacteria and cellulose degrading bacteria on 1 kg of kitchen waste, incubating mixture at 28-37 degrees C for 24 hours, and testing degradation effect of the microbial composition within standard ranges i.e. testing starch degrading effect within standard range of 16.59-35.23%, testing oil degrading effect within standard range of 19.37-40.65%, testing protein degrading effect within standard range of 16.32-28.63% and testing cellulose degrading effect within standard range of 2.58-4.82 to obtain best microbial composition, and (d) preparing inocula carriers, and (e) subjecting the best microbial composition obtained in the step (c) to centrifugation at 5000 revolutions per minute, collecting pellet, and mixing the pellet with the carrier under aseptic conditions.
