Abstract

The invention relates to a method for production of refined dried ramie by microbial blending and degumming, Bacillus Bacillus sp., HG-116 and Bacillus Bacillus sp., HG-247 are used as strains for respective strain activation step and enlarged cultivation step to obtain a bacterium fluid, and the bacterium fluid and water are mixed for fermentation cultivation, enzyme production cultivation and biological degumming to achieve the purpose of rapid and thorough removal of various ramie gum components. After optimization of types of culture mediums and fermentation conditions, two kinds of microorganisms can grow well, cultivation period is short, technical indexes of the produced refined dried ramie are far above the national standards of first-level refined dried ramie, the refined dried ramie is very fluffy due to super low residual gum rate, a spinning pretreatment process is simple, dust is significantly reduced, spinning end breakage rate is low, ramie yarn comprehensive production cost is reduced, and ramie yarn quality is improved significantly.

Description

technical field

[0001] The invention belongs to the technical field of microorganisms, and more specifically relates to a method for producing ramie fine-dried hemp by mixing and degumming microorganisms. Background technique

[0002] In addition to cellulose, ramie bast also contains colloidal components such as hemicellulose, pectin, and lignin. These colloids wrap the fibers and make them cemented together to form a hard sheet-like bundle. It is necessary to remove the colloids in a certain way to obtain fiber raw materials for spinning and weaving. The degumming method is directly related to the quality of ramie fiber, as well as the environmental protection problems caused by degumming wastewater and waste residue.

[0003] Microbial degumming is to inoculate ramie bast with strains capable of degrading gelatin, and the degumming bacteria secrete degumming enzymes to degrade ramie gelatin, and use the degradation products as nutrient sources for growth and reproduction...
