Cellulose degradation bacterium CX9 from termite gut and application thereof

Abstract

The invention discloses a cellulose degradation bacterium CX9 from termite gut and application thereof. The strain is preserved in the China Center For Type Culture Collection in No.3, No.1 yard on Beichen West Road, Chaoyang District, Beijing on August 27th, 2018 and has the preservation number of CGMCC No.16343. The strain is gram-positive bacilli without capsules, endogenous spores can be seenafter spores are dyed, bacterial colonies are each in a crack shape and are independent of one other or connected to form a piece, and the bacterial colonies have the white color and complete edges. The strain is a facultative anaerobic strain capable of generating cellulase; the strain has the CMCase enzyme activity of 70.4 IU / mL and CX enzyme activity of 25.23 IU / mL within 48 hours. The strain has quite high biodiversity value and also has further research scientific value in the development and application of the fermentation and reutilization technology of cellulose-enriched crops and traditional Chinese medicines.

Description

Technical field [0001] The invention relates to a cellulose degrading bacterium CX9 from the intestine of termites and its application. Background technique [0002] Lignocellulose is the main structural component of plant cell walls. It is composed of lignin, cellulose and hemicellulose which are interlocked with each other and form a spatial network structure by covalent bonding. 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 crop straws, cash crops and medicinal plant wastes rich in lignocellulose are rich in resources, and the output is huge. However, for a long time, due to factors such as lifestyle, processing technology and poor feedability, a large number of crop straws and medicinal plant wastes have been discarded or burned, and they have not been rationally developed and utilized. According to the survey, the curre...

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
