NOVELTY - Microbial inoculum capable of degrading domestic garbage is formed by cellulose degrading bacteria and leachate chemical oxygen demand (COD) degrading bacteria in the volume fraction of 1-5:1 (volume/volume). The cellulose degrading bacteria are formed by Bacillus sp. of high producing cellulose, Cellulomonas sp., Trichoderma sp. and Aspergillus. The leachate COD degrading bacteria are formed by Pseudomonas sp., Flavobacterium sp. and Acinetobacter sp..    USE - The high efficiency microbial inoculum is useful for degrading domestic garbage by treating organic wastes and utilizing reclamation substances (claimed).    ADVANTAGE - The microbial inoculum is highly flexible and environment-friendly. The microorganisms in the inoculum have synergistic activity.    DETAILED DESCRIPTION - Microbial inoculum capable of degrading domestic garbage is formed by cellulose degrading bacteria and leachate chemical oxygen demand (COD) degrading bacteria in the volume fraction of 1-5:1 (volume/volume). The cellulose degrading bacteria are formed by Bacillus sp. of high producing cellulose, Cellulomonas sp., preferably Cellulomonas fimi, Trichoderma sp., preferably Trichoderma viride and Aspergillus in the ratio of 3:3:2:2. The leachate COD degrading bacteria are formed by Pseudomonas sp., Flavobacterium sp. and Acinetobacter sp. in the ratio of 7:2:1. An INDEPENDENT CLAIM is included for preparation of microbial inoculum capable of degrading domestic garbage, which involves (a) activating bacterial strain continuously by adding garbage leachate in oriented way, inoculating degrading bacteria of cellulose into beef extract peptone medium, inoculating epiphyte into potato culture medium, inoculating leachate COD degrading bacteria into beef extract peptone medium and culturing until the growth phase, and (b) mixing bacteria with epiphyte of cellulose degrading bacteria, adjusting turbidness (optical density 600) of the suspension liquid within 0.8 plus minus 0.1, and uniformly mixing the cellulose degrading bacteria with the leachate COD degrading bacteria in the volume ratio of 1-5:1.
