Deodorizing compound inoculum for feces of livestock and poultry and preparation method of deodorizing compound inoculum

Abstract

The invention discloses a deodorizing compound inoculum for feces of livestock and poultry and a preparation method of the deodorizing compound inoculum, and relates to the field of microbe applications. The deodorizing compound inoculum and the preparation method are provided aiming at the problems that the technical cost for chemical deodorization is high, the reaction is complicated, secondarypollution is generated, and the commercial biological deodorant is poor in adaptation and single in function. The deodorizing compound inoculum for feces of livestock and poultry comprises five species of bacteria including bacillus amyloliquefaciens, Alcaligenes faecalis subsp.faecalis, Arthrobacter humicola, Streptomyces levoris and Micromonospora yulongensis. The preparation method of the deodorizing compound inoculum comprises the following steps: fermentation of single bacterial strains, preparation of the compound inoculum, and adding of a fresh culture medium, an activating agent and aprotection agent. The technical scheme has the beneficial effects that the treatment speed and utilization ratio for feces are improved, and the deodorizing effect is rapid and lasting.

Description

technical field

[0001] The invention relates to the field of microorganism application, in particular to a compound microbial agent for deodorizing poultry manure and a preparation method thereof. Background technique

[0002] With the continuous improvement of people's living standards, the demand for livestock and poultry products is also increasing. The Food and Agriculture Organization of the United Nations (FAO) predicts that the world's demand for meat products will increase by 73% by 2050. In order to meet such a rapidly growing demand for meat products, animal husbandry has gradually developed from traditional free-range farming to intensive and large-scale development, followed by a large amount of livestock and poultry manure that cannot be effectively treated and has become a major issue. sources of environmental pollution. Relevant statistics show that in 2010, the national production of livestock and poultry manure was about 4 billion tons, of which less than ...
