Title:
METHOD FOR RAPIDLY REDUCING ANTIBIOTICS AND RESISTANCE GENES IN ORGANIC SOLID WASTE
Document Type and Number:
WIPO Patent Application WO/2019/100579
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for rapidly decreasing antibiotics and resistance genes in organic solid waste, which belongs to the field of organic solid waste treatment. The present invention utilizes aerobic fermentation bacteria capable of withstanding a temperature of at least 80 °C and controls the pile temperature of no lower than 80 °C for fermentation for at least 5 to 7 days so as to carry out ultra-high temperature aerobic fermentation of organic solid waste, being capable of obtaining effects of rapidly and stably decreasing antibiotics and antibiotic resistance genes in organic solid waste The ultra-high temperature aerobic fermentation not only can rapidly degrade antibiotics and ARGs, but also can change the whole microbial colony structure in the pile, kill 90% of the ARGs-bearing microorganisms (mainly, Proteobacteria and Bacteroidetes), reduce the risk of gene transfer of ARGs, and control the diffusion thereof from the source, thereby ensuring that ARGs will not rebound. Not only the treatment of organic solid waste is achieved, but also the dual effects of efficiently removing antibiotic residues and resistance gene contamination are obtained. The method of the present invention does not need external heating, and only relies on the metabolic energy of the thermophilic microorganism to reach the high temperature of fermentation, having low energy consumption and being environmentally friendly.
