Problems solved by technology

However, there are few commercial bacteria agents for the degradation of kitchen waste and wheat straw
This leads to the poor adaptability of the existing bacterial agents to the degradation of kitchen waste and wheat straw, and the problems of slow heating and low degradation efficiency

Embodiment 1

[0028] The test of this example is located in the laboratory of Shenzhen Lvhang Interstellar Space Technology Research Institute, Guangdong Province, including a microbial composite bacterial agent for treating kitchen waste wheat straw and its preparation method. The preparation method steps are as follows:

[0029] (1) prepare the culture medium required for bacterial classification fermentation, subpackage in different Erlenmeyer flasks and sterilize to obtain shake flask fermentation culture medium;

[0030] (2) Take out the strains preserved with 20% glycerol in the refrigerator at -80°C, inoculate each strain into the shake flask fermentation medium of step (1) in the biological safety cabinet after thawing;

[0031] (3) Place the shake flask fermentation medium of step (2) in a constant temperature shaker incubator for shaker culture to obtain a fermentation broth, the effective number of viable bacteria in each fermentation broth is greater than 1×108CFU / g. Wherein th...

Abstract

The invention relates to a microbial composite agent for treating kitchen waste wheat straw and a preparation method of the microbial composite agent. The microbial composite agent is used for treating the kitchen waste wheat straw and is prepared from coccus, bacillus, saccharomycetes, mould and mycobacteria. The microbial complex agent is prepared by performing shake-flask fermentation in a constant-temperature shaking incubator and then preparing freeze-dried powder by using a vacuum freeze-drying device. The strains are rich in variety and free of antagonism, have high degradation capacityon starch, protein, grease, lignocellulose and other substances, and can effectively degrade kitchen garbage and wheat straw. The microbial composite agent for treating the kitchen waste wheat strawhas the advantages of low equipment requirement, low cost, high pertinence, simple preparation process and the like. The agent can effectively increase the temperature of a pile body in practical application, so that the problems of low temperature rise speed, low degradation efficiency and the like are solved, the treated product is returned to the field to improve the soil structure, the chemical fertilizer consumption is reduced, and crops are prevented from being affected by diseases and pests.

Description

technical field [0001] The invention relates to solid waste treatment technology, in particular to a microbial composite bacterial agent for treating kitchen waste wheat straw and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy and the continuous improvement of people's living standards, the amount of solid waste generated has gradually increased. Among them, wheat, as the main food crop, is growing day by day, and this will inevitably produce a large amount of inedible parts of plants (wheat straw); kitchen waste is a solid waste that will inevitably be produced in large quantities in people's daily life. The greasy appearance and perishable nature will greatly affect the beauty of the city and the living environment if it is not dealt with in time. Therefore, how to effectively deal with solid waste such as kitchen waste and wheat straw has become a problem that must be solved. [0003] At pr...
