Problems solved by technology

[0004] At present, there are many technologies and products related to decomposing bacteria agents, but most of them have the following problems: First, the fermentation efficiency is not high
The performance is slow start, slow deodorization, large amount of addition, and long fermentation cycle
Second, it is not resistant to low temperature
Most of the strains used are medium-temperature, suitable for use at an ambient temperature above 20°C. If the temperature is low, the fermentation will take a long time to start or will not ferment, and it will be difficult to carry out fermentation production in winter
Three is a single purpose
Most of them are only used for livestock and poultry manure fermentation or straw fermentation, resulting in high R&D and production costs
The main reasons for the above-mentioned problems are: firstly, the composition of the strains of the starter is unreasonable, and some strains are simple combinations without considering the functional complementarity and mutual symbiosis between the constituent strains, resulting in low fermentation efficiency, especially at low temperature. slow or no fermentation
Second, the composition of the strain is a simple combination with a single function
[0008] The applicant has not seen any literature reports similar to the technical solutions and technical effects of the present application in the prior art

Abstract

The invention belongs to preparation of a microbial decomposition agent, and particularly relates to a microbial decomposition agent, preparation thereof and an application of the microbial decomposition agent in fermentation and decomposition of organic materials. The preparation method comprises the following steps: preparing compound original bacterium powder from Wickerhamomyces anomalus CGMCC No.20654 and rhizopus oryzae CGMCC No.3.5085, and mixing the compound original bacterium powder with an organic material carrier and an inorganic carrier, so as to prepare the microbial decomposition agent. The problems that in the prior art, strains are started slowly or are not started at low temperature, and the purpose is single are solved. The strains can be started at the environment temperature of 15 DEG C, crop straw and livestock and poultry manure are effectively decomposed and degraded, the decomposition speed is high, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the preparation of a microbial decomposing agent, in particular to a microbial decomposing agent which can be started at a relatively low ambient temperature and its preparation and application in organic material fermentation and decomposing. Background technique [0002] A large amount of organic waste is produced in industries such as breeding, planting, sewage purification, food processing, and pharmaceuticals. If it is not handled properly, it will lead to pollution of the surrounding environment, groundwater, and farmland, and adversely affect production, life, and people's health. High-temperature aerobic fermentation technology can generate a large amount of biological heat, kill insect eggs, pathogenic bacteria, grass seeds, etc., and at the same time convert macromolecular organic substances such as cellulose, lignin, and protein into humus, amino acids, etc., and release nitrogen in them Phosphorus, potassium and med...
