Breeding of a fast retting bacterium and appraisal of retting function in hemp

Breeding and selection of hemp retting strains and their retting functions were studied aiming at problems such as unstable quality,low fiber intensity,low products rate,serious environment pollution brought about by chemical retting technology.After collected strains broadly,we selected them and mutated strains,sifted a new strain.This strain can accomplish hemp retting within(16 h.) Under laboratory condition retting of hemp this strain has advantages of short retting period,high yield and superior quality.Compared with traditional retting method,the fast retting technique can shorten retting time by 90% or more,the output for short fiber has been increased by 2.1%, and the fiber strength has been increased by 7.9%.And the fiber has got light color,homogeneous texture and good luster.
