Abstract

The invention provides a livestock and poultry manure deodorizing composite microbial inoculant and a preparation method and application thereof. The livestock and poultry manure deodorizing microbial agent comprises the following bacterial strains in parts by cell number of each bacterial strain accounting for the total cell number of compound bacteria: 15-20 parts of Ochrobactrum sp.DSM717; 10 to 20 parts of Rummaliibacillus pycnus DSM 15030, and 10 to 20 parts of an additive, 10 to 20 parts of Brevibacillus fuszeri DSM9887, and 10 to 20 parts of a mixture of the brevibacillus fuszeri DSM9887; 10 to 15 parts of Enterococcus faecalis DSM2981, 10 to 15 parts of Eurococcus faecalis DSM2981; 5 to 10 parts of Methylobacter aminos JCM 8240, 5 to 10 parts of Metylobacter aminos JCM 8240, 5 to 10 parts of Metylobacter aminos JCM 10 to 15 parts of an Acinetobacter indicus DSM 100979, 10 to 15 parts of an Acinetobacter indicus DSM 100979; the preparation method comprises the following steps: preparing the following raw materials in parts by weight: 15-20 parts of bacillus velezensis CGMCC NO.23309; and 10 to 20 parts of Lactococcus lactis CGMCC NO.22594, and 10 to 20 parts of Lactococcus lactis CGMCC NO.22594. The microbial agent disclosed by the invention can treat foul smell from the source, and the strains do not have antagonism, so that the microbial agent is good in synergistic effect, high in foul smell removal rate and effective for a long time.

Description

technical field [0001] The invention belongs to the technical field of microbial bacterial agents related to environmental protection, and in particular relates to a microbial bacterial agent for deodorizing livestock manure and its preparation method and application. Background technique [0002] As one of the environmental hazards, stench can not only bring discomfort to people's sense of smell, but also cause functional diseases such as anorexia, insomnia, memory loss, and irritability to people who live in a stench-polluted environment for a long time. People's feeling of strange smell is because all kinds of smelly molecules of solid, liquid and gas radiate and flow in the air, which stimulates people's olfactory cells and transmits them to the human brain, so that people feel the smell . [0003] There are many sources of odor pollution, a wide range of pollution, and many industries involved, mainly including livestock and poultry farms, slaughterhouses, garbage trea...
