Abstract:

In this study, it was proposed that the microbiodegradant of food waste, namely CHUYUBAO-FWMDA-001, a kind of bactericide, was formed by in-situ fermentation using Cenchrus fungigraminus juice to enrich microorganisms, which could be used for microbial degradation of food waste. The identification results of CHUYUBAO-FWMDA-001 showed that there were abundant degrading microorganisms (34 species). Under the same conditions (outdoor temperature 20℃), the effect of adding bactericide on the treatment of kitchen waste was significantly different. After treatment time of 60h, the degradation rate of ordinary garbage cans without adding bacteria (treatment group A) was 10.66±0.73%, while that of adding bacteria (treatment group B) was 15.33±1.21%, and the degradation rate of adding bacteria group was 43.80% higher than that of the non-adding bacteria group. The degradation rate of the smart trash can without bacteria (treatment group C) was 33.33±2.98%, and that of the bacteria group (treatment group D) was 99.33±10.5%, and the degradation rate of the bacteria group was increased by 199.33% compared with the non-bacteria group. CHUYUBAO-FWMDA-001 has the advantages of low cost, abundant sources, complementary flora and stable effect. The combination of CHUYUBAO-FWMDA-001 and smart trash can can realize the efficient treatment of deodorization, sterilization, corrosion prevention and reduction of kitchen waste by using fungus powder as fermentation substrate and adding bacteria, heating and stirring. Fermentation of kitchen waste into organic fertilizer for agricultural production. CHUYUBAO-FWMDA-001 provides a stable and reliable source of microbial agent for the treatment of food waste, showing the prospect of efficient application of microbial treatment of food waste.
