Industrial fermentation ramee rapid extraction technique for Erwinia

Abstract

The invention discloses a technique for rapidly extracting ramie hemp erwinia bacterium factory production fermentation, the technique comprises preprocessing material, immersing or sprinkling and inoculating, immersing or fermenting, deactivating with hot water, and the procedure of circulation washing, water dressing and fiber finish, erwinia bacterium which has broad-spectrum and high effective to degumming, pulping and saccharifying of herb fiber material, and bacterial agent preparation and activated technical parameter. The erwinia bacterium addicts the mannose, the peak for secreting non-cellulose to degrade key enzyme (pectic enzyme, beta-mannase and xylanase) can be achieved through purely culturing for 7h to 9h. Bacterial agent is inoculated on herb fiber material such as ramie and the like for activating the bacterial agent for 5h-6h, fermentation forage fodder turns to blue after fermenting for 5h-6h, pectine, hemicellulose and partial lignin which are partially degraded and associated in fiber cell are stripped, non-cellulose residues which are absorbed on fiber can be removed by means of the flushing of high-pressure flushing, and the purpose of extracting net fiber can be reached.

Description

technical field [0001] The invention belongs to the field of ramie biological degumming in the textile industry, and in particular relates to an Erwinia bacillus and a process for extracting ramie fibers. Background technique [0002] The current hemp degumming and grass pulping enterprises all use chemical methods. There are three outstanding problems in chemical degumming or pulping methods: one is high cost and high energy consumption, two is a lot of fiber loss and structure damage, and the third is environmental pollution serious. In particular, chemical methods damage the inherent morphology and structure of fibers while degrading non-cellulose, making fiber products lose many excellent properties. These problems have already become the restrictive factors of industrial development. In order to solve the problems existing in traditional and conventional methods, extensive researches on "biological degumming", "biological pulping" and "biological saccharification" hav...
