Abstract

The invention provides a technology for degrading bast fiber lignin. The technology comprises the steps of defibering the bast fiber raw materials; sieving and dedusting; swelling up; extruding and draining water; soaking in a bacteria solution, wherein the bacteria solution contains acinetobacter lwoffii with storage number of CGMCC NO.5973, and multiple microorganisms with storage number of CGMCC No.5975; the multiple microorganisms contain wickerhamomyces anomalus and phanerochaete chrysosporium and pleurotus ostreatus; and then processing the bast fiber raw material by washing, non-chlorine bleaching, washing and drying to obtain the bast fiber lignin. The technology for degrading the bast fiber lignin has obvious technical effects, such as high fibrousness, high yield, short operationtimes, low cost and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of microorganisms and biological pulping, and in particular relates to a process for degrading hemp lignin and its application. Background technique [0002] Pulping technology refers to the removal of lignin and pectin and other substances from plant straws, branches, trunks and other raw materials through degradation (or release). Pulping technology includes chemical pulping and biological pulping. Since the chemical pulping method will bring serious environmental pollution and high cost, people have gradually developed and adopted biological pulping technology to fundamentally solve the pollution problem of chemical pulping, and screened from nature to selectively degrade lignin. Excellent strains for biopulping industry. [0003] In nature, the microorganisms that can decompose lignin are mainly wood decaying fungi belonging to macrofungi, and very few are bacteria and actinomycetes; wood decaying fung...
