A MICROBIAL CONSORTIUM USED IN FASTER RETTING OF JUTE AND MESTA

摘要

A microbial consortium for fast retting of bast fibre comprising three Bacillus pumilus strains containing Bacillus pumilus IMAU 80221, Bacillus pumilus GVC 11 and Bacillus pumilus SYBC-W by 16S rDNA sequencing (ribotyping) of a 977 bp lengh of 16S rRNA gene, mixed in a ratio of 1:2:1 or 1:1:2. or 1:1:1. In the microbial consortium of the present invention three isolates are identified as different strains of Bacillus pumilus, namely Bacillus pumilus IMAU80221; Bacillus pumilus GVC11; Bacillus pumilus SYBC-W by 16S r DNA sequencing (ribotyping) of a 977 base pair fragment. The present invention also involves a process for accelerated removing of pectic substances from jute and mesta using microbial consortium in a predetermined amount in a retting tank to remove pectin and xylan containing material from bast during water scare conditions utilizing less volume of water, said process is carried out at a pH range between 5.0 and 11.0 with three peaks at 6.0, 8.0 and 10.0, preferably at pH10.0.
