Bacillus firmus CX8 from termite gut and application of bacillus firmus CX8

Abstract

The invention discloses bacillus firmus CX8 from a termite gut. The strain is collected in the China General Microbiological Culture Collection Center (CGMCC) with the address of No.3, No.1 Yard, Beichen West Road, Beijing 3 Chaoyang District on August 27th, 2018, and has a collection number of CGMCC No. 16342. The strain is gram-positive bacillus and is free of capsule, endogenous spores can be seen through spore staining, a bacterial colony is round and single, the color of the bacterial colony is white, and the edge of the bacterial colony is complete. The strain is a facultative anaerobicstrain for producing cellulase; and within 48 hours, the CMCase enzyme activity of the strain is 67.8 IU/mL, and the CX enzyme activity of the strain is 20.96 IU/mL. The strain not only has very highbiodiversity value, but also has scientific value for further research in development and application of cellulose-enriched crop and traditional Chinese medicine fermentation recycling technologies.

Description

technical field [0001] The invention relates to a strain of bacillus firmus CX8 from termite gut and application thereof. Background technique [0002] Lignocellulose is the main structural component in the plant cell wall. It is composed of lignin, cellulose and hemicellulose, which are covalently bonded to form a spatial network structure. Due to its large molecular weight, complex structure and stable properties, lignocellulose is extremely difficult to decompose under natural conditions. In my country's agricultural production, various lignocellulose-rich crop straws, economic crops and medicinal plant waste resources are abundant and the output is huge. However, for a long time, due to factors such as lifestyle, processing technology and poor feedability, a large amount of crop straw and medicinal plant waste have been discarded or burned, and have not been rationally developed and utilized. According to the survey, the utilization rate of straw in our country is abou...

Problems solved by technology

The research barrier of the termite intestinal symbiosis system is the isolation and cultivation of a large number of intestinal microorganisms. Given the strict environmental conditions required for the survival and reproduction of intestinal bacteria, culture techniques are often not suitable for their research
