Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the examples.

[0021] A fiber-degrading bacterial strain and its enzyme-producing method, specifically: a strain of Ochrobactrum intermedium XW2020005, which is isolated from sugarcane leaf decomposing materials, and whose preservation registration number is CGMCC No.20427, and the preservation time is August 14, 2020 day.

[0022] The colony and morphological characteristics of the strain are as follows: the colony on the NA solid medium is milky white, round, smooth and raised, with neat edges and no pigmentation. It is a Gram-negative bacterium with an average size of long (0.8-1.6 ) μm × (1.0-2.4) μm.

[0023] The 16S rDNA sequence of the strain has been registered in GenBank with accession number MW538324.

[0024] The 16S rDNA sequence phylogenetic tree of the strain showed that the strain was highly homologous to Ochrobactrum intermedium.

[0025] The liquid culture of the str...

Abstract

The invention discloses a fiber degradation strain and an enzyme production method thereof, and particularly relates to Ochrobactrumintermedium XW2020005 which is separated from a sugarcane leaf decomposition material. The preservation registration number is CGMCC No.20427. The strain has the advantages that the strain is separated from a sugarcane leaf decomposition material, can generate filter paper enzyme activity, endoglucanase, beta-glucosidase and other cellulase in the growth and reproduction process, and can decompose sugarcane leaves and other straw in a low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of agricultural resources and environmental microorganisms, in particular to a fiber-degrading bacterial strain and an enzyme-producing method thereof. Background technique [0002] The sugar industry is one of the important economic pillar industries in Guangxi, and it is a "100-billion-billion-dollar industry" that Guangxi focuses on developing. In recent years, Guangxi has a sugarcane planting area of ​​about 1 million ha, and its sugar production has ranked first in the country for more than 20 consecutive years, accounting for more than 60% of the country's total sugar production. It plays a pivotal role in my country's sugar production and safety. [0003] Leave a large amount of sugarcane leaves (including leaf sheaths, etc.) after the sugarcane is harvested, and the output of sugarcane leaves is about 6-10t / ha, so the annual output of sugar cane leaves in Guangxi alone can reach 600-10 million tons. ...
