Composite fermentation inoculant for processing animal wastes, and preparation method and application thereof

Abstract

The invention discloses a composite fermentation inoculant for processing animal wastes, and a preparation method thereof. The composite fermentation inoculant is characterized in that the active components of the composite fermentation inoculant comprise Bacillus beringensis, Rhodobacter sulfidophilus and Cellulomona ssp.; the mass ratio of the Bacillus beringensis to the Rhodobacter sulfidophilus to the Cellulomona ssp. is 0.5-1.5:0.5-1.5:0.5-1.5; and the preparation method comprises the following steps: carrying out inclined strain culture of the Bacillus beringensis, the Rhodobacter sulfidophilus and the Cellulomona ssp.; carrying out liquid seed enlargement culture to obtain a Bacillus beringensis broth, a Rhodobacter sulfidophilus broth and a Cellulomona ssp. broth; and mixing the above broths according to a mass ratio of 0.5-1.5:0.5-1.5:0.5-1.5, inoculating the mixed broth to a solid enlargement culture medium with the inoculation amount of 4-5%(w / v), and carrying out enlargement culture to obtain the composite fermentation inoculant. The composite fermentation inoculant has the advantages of deodorizing, inhibition of the growth of pathogenic microorganisms in the animal wastes, improvement of the content of proteins in the animal wastes, high processing efficiency and strong pertinence.

Description

technical field [0001] The invention relates to a composite fermentation bacterial agent and a preparation method thereof, in particular to a microbial composite fermentation bacterial agent for treating livestock and poultry waste, a preparation method and an application thereof. Background technique [0002] Livestock and poultry waste refers to a large amount of aquaculture waste produced in the process of livestock and poultry breeding, which has become one of the three major sources of environmental pollution due to its growing discharge. Livestock and poultry waste mainly includes livestock and poultry manure, urine, feed residues and sewage from washing pens. In addition to polluting soil and water bodies, livestock and poultry waste will also produce a large amount of odorous gases such as ammonia, hydrogen sulfide, mercaptan and methyl mercaptan, which will adversely affect the environment and the normal life of humans and animals. [0003] At present, domestic lar...

Problems solved by technology

In addition to polluting soil and water bodies, livestock and poultry waste will also produce a large amount of odorous gases such as ammonia, hydrogen sulfide, mercaptan and methyl mercaptan, which will adversely affect the environment and the normal life of humans and animals.

[0003] At present, domestic large and medium-sized farms generally adopt the model of standard discharge, planting and breeding balance, and biogas ecology to deal with livestock and poultry waste, but these methods require high capital and technical requirements; many small pig farms continue to use traditional waste directly as agricultural fertilizer method, low waste utilization rate and easy to pollute the environment

In recent years, fermented bed cultivation introduced from Japan has attracted widespread attention due to its easy operation, low capital investment, and good treatment effect. The degradation efficiency of livestock and poultry waste is low, and its treatment effect on livestock and poultry waste is not very significant, which affects the promotion of fermentation bed breeding technology on a large scale. Therefore, an efficient and targeted fermentation bed compound bacterial agent is urgently needed to solve the problem. The above technical problems
