A kind of biogas fermentation promoting bacterial agent

Abstract

The invention provides a biogas fermentation promotion agent. The promotion agent is prepared from a following microorganism culture solution according to the volume part of the microorganism culturesolution, 15 to 20 parts of firmicutes, 15 to 20 parts of bacteroides, 3 to 5 parts of spirochaeta, 4 to 6 parts of thermotoga, 3 to 5 parts of deltaproteo bacteria, 3 to 5 parts of synergistetes, 3 to 5 parts of cellulomonas and 35 to 40 parts of euryarchaeota. According to the biogas fermentation promotion agent provided by the invention, selected 13 anaerobic fermentation functional strains arepreserved in strain preservation centers at home and abroad and are easy to obtain, culture and compound; according to the fermentation promotion agent provided by the invention, various microorganisms are matched reasonably and can be adaptive to fermentation raw materials with different types so that various raw materials can be rapidly degraded and converted into biogas; according to the biogas fermentation promotion agent, various microorganisms have the same or similar growth culture conditions and the promotion bacterium agent can normally grow and metabolize under the same environmentcondition and play the largest role.

Description

technical field [0001] The invention relates to resource utilization of organic waste, in particular to a biogas fermentation-promoting bacterial agent, which belongs to the fields of biological fermentation technology and renewable energy. Background technique [0002] As a renewable resource of ground biomass, biogas has a long history of use. However, with the increasing demand for economical and scientific biogas production technology, many related technologies have been developed. Among them, the research on biogas accelerator is a hotspot. [0003] At present, the main accelerators can be simply divided into chemical substance accelerators and bacterial agent accelerators. [0004] The main research and development ideas of chemical substance accelerators are to promote the growth of methanogenic bacteria and improve their gas production efficiency, such as the Chinese patent with the authorization number CN103642846B and the Chinese patent with the publication numbe...

AI Technical Summary

Problems solved by technology

[0007] However, the research in this field is not yet mature in terms of bacterial agent accelerators, and there is still a lot of room for improvement in the technical effects of gas production efficiency, gas production cycle and raw material adaptability

In addition, although some accelerators have good effects, the strains used are difficult to obtain or require rigorous isolation and cultivation, which affects their popularization and application.
