The invention discloses a preparation method of a
bacterial strain for aerobic composting of kitchen waste and a
grease degrading
bacterial agent thereof, which is characterized by comprising the following steps of: enriching and domesticating a microbiota by using a
hydrolysis ring method by adopting an enrichment
domestication and separation purification method, separating and screening the
bacterial strain for degrading animal
grease, the method specifically comprises the following steps: collection of microbial communities, enrichment
domestication, separation and purification of strains, and
primary screening and secondary screening of the strains; the liquid
grease degrading
bacterial agent is prepared by compounding
bacterial strain pseudomonas alcaligenes liquid,
brevibacillus parabrevis liquid,
candida lipolytica liquid and
bacillus amyloliquefaciens liquid according to the volume ratio of 1: 1: 1: 1. The
solid grease degrading microbial inoculum is prepared by mixing the liquid microbial inoculum and the conditioner according to the volume-weight ratio of the
dry weight of the liquid microbial inoculum to the conditioner of 1: 1. Compared with the prior art, the method has the advantages that
animal fat is efficiently degraded, the composting period is short, stink emission is avoided, the composting
treatment effect is improved, efficient resourceful treatment of kitchen waste is promoted, the influence on the environment is reduced, and the method has good application prospects, economic value and
social benefits.
