Abstract

The invention provides a Nanhai Bacillus, the Nanhai Bacillus is Bacillus Nanhai XJC‑YS‑26, which is registered and preserved in the China General Microorganism Culture Collection and Management Center, and the preservation number is CGMCC No.19591. Nanhai bacillus XJC-YS-26 of the present invention has good enzymatic activities such as producing endoglucanase, exoglucanase, β-glucosidase, can effectively degrade cellulose and hemicellulose, and also has Produce α-amylase, xylanase, pectinase and protease and other enzymatic activities, which can effectively degrade starch and protein, and have high-efficiency degradation function for crop straw, etc., which can quickly decompose crop straw, release nutrients, and contribute to the environment Other microorganisms in it provide nutrition, improve sudden micro-ecology, avoid environmental pollution, and have high practical value in the utilization of waste resources.

Description

technical field [0001] The invention relates to the field of biology, in particular to a bacillus south sea with cellulolytic effect and application thereof. Background technique [0002] Cellulose is the main component of plants, and its content can reach more than 40%. It is also the most abundant renewable resource in the world. Every year, the global straw crops reach 2.9 billion tons, and most straw crops are disposed of by direct burning, which not only causes serious environmental pollution, but also seriously wastes resources (Feng Haiwei et al., 2013). If cellulose can be effectively converted and utilized, it will not only solve the problem of environmental pollution caused by burning crop straw from the root, but also convert its energy into energy for human use. Since cellulose is a high-molecular compound containing a large number of high-energy hydrogen bonds, and is difficult to degrade and hydrolyze, the current resource utilization of cellulose is relativel...
