Abstract

The invention relates to the technical field of a biological agent, and particularly relates to a cellulose degradation bacteria agent and a raw material strain, and preparation methods and applications of the cellulose degradation bacteria agent and raw material strain. The compound bacteria agent for degrading cellulose mainly comprises a paecilomyces varioti MM2 strain, an aspergillus fumigates MM6 strain, a candida rugosa MJ4 strain, and a bacillus licheniformis MX8 strain. The cellulose can be efficiently degraded and utilized by the compound bacteria agent disclosed by the invention, the compound bacteria agent can be used as a detonating agent and an enhancer of wine sediment compost, the compost process can be accelerated, the compost rotten degree is improved, an organic fertilizer is fabricated, and the cellulose degradation bacteria agent is especially applicable to resourceful treatment of lignocelluloses solid waste and production of the organic fertilizer by using the wine sediment.

Description

technical field [0001] The invention relates to the technical field of biological bacterial agents, in particular to a cellulose-degrading bacterial agent, a raw material strain, a preparation method and an application thereof. Background technique [0002] Composting technology is a technical means to make organic fertilizer through microbial fermentation and decomposing organic solid waste under high temperature and high humidity conditions. In the composting process of lignocellulosic organic solid waste, the degradation of cellulose is the key, because the cellulose content is the highest and the degradation is the slowest. In aerobic composting, it is difficult to effectively degrade the cellulose in the compost material only by relying on the original indigenous microorganisms in the compost material. Therefore, it is necessary to introduce specific exogenous microorganisms to accelerate the compost decomposition process. For the bacterial agent that degrades cellulos...
