A cellulose-degrading bacterium cx9 from termite gut and its application

Abstract

The present invention discloses a cellulose-degrading bacterium CX9 from termite gut. The strain was preserved in General Microbiology Center of China Microbiological Culture Preservation Management Committee, No. 1, No. 1 Beichen West Road, Chaoyang District, Beijing on August 27, 2018. , the deposit number is: CGMCC No.16343. The strain is Gram-positive bacillus, without capsule, endophytic spores can be seen in spore staining, the colony is cracked, the colony is single or connected sheet, the color of the colony is white, and the edge of the colony is complete. The strain is a facultative anaerobic strain producing cellulase; within 48 hours, the CMCase activity of the strain was 70.4IU / mL, and the CX activity was 25.23IU / mL. The strain not only has high biodiversity value, but also has scientific value for further research in the development and application of cellulose-enriched crops and traditional Chinese medicine fermentation and reuse technology.

Description

technical field [0001] The invention relates to a cellulose degrading bacterium CX9 from termite intestinal tract 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 ou...

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
