A study was conducted to identify a microbial consortium that can enhance the coir retting process. In this, piolet scale retting were performed for coconut husks of Sri Lankan tall cultivar (CRIC 60) utiliZing twelve microbes isolated from naturalretting pitts located in different parts of the country. Effectiveness of these microorganisms in coir retting was evaluated by inculating them individually and in combinations of two/three strains and retting for a one month period. Innoculated samples were collected at biweekely intervals to evaluate the fibre extraction using the traditional Ceylon drum. The fibre samples were observed visually and microscopically for the pith contentadhered to the blace and fibre and they were also analysed for percentages of bristle fiber, balace, pith content and pectin content. The ret liquor samples were also analysed to determine pH, EC, total plate count and tannin content. Results show that the good quality bristle fiber can be obtained using consortium of microorganisms namely, Bacillus fimus, Bacillus badius and Bacillus macerans within a period of from 21 years.
