RESEARCH ON THE SELECTION OF MICRO-ORGANISM DECOMPOSING ORGANIC MATTERSGENERATED IN THE PRODUCTION OF YARN FROM RAMI
Keywords:Green thorn (Ramie), Bioproducts, Cellulose resolution
During the process of crop restructuring, thorns emerged as a bright object for many localities to choose in place of other inefficient crops. The area of green hemp for fiber production in Vietnam is over 1,000 hectares (2018). After taking the bark to make yarn, a large amount of rami waste is released into the environment. These wastes, after a period of time, in order to be naturally biodegradable, create a bad smell and rot for the surrounding environment. There is a need for a specialized microbial product to treat rami waste to clean up the environment, while creating an organic fertilizer supply back to the soil growing rami. To solve this problem, the research has collected, isolated and selected the strains of microorganisms having capability of resolving cellulose and lignin, the main components in the stems of rami. The results have selected four strains of microorganisms with high cellulose and lignin resolution activityto produce bio-degradable products of rami, including actinomycetes RR04, BG05, BG08, bacteria RR05. The study has also selected the most suitable fermentation medium, MT2, so that the strains of microorganisms have the best biological activity in treating hemp residue.
