RESUMEN
The enzymatic degumming of ramie bast fibers is a kind of method with high performance, superior quality, free from pollution that directly makes use of the extra cellular enzyme or zymin produced in the fermentation process of microorganisms to degrade the gum. So far, many investigations regarding this aspect have been conducted at home and abroad, and screened various strains including aerobic bacteria and anaerobic bacteria. Comparison with the chemical degumming, the enzymatic degumming shows the advantage of improving the quality of refined dried-ramie, significantly lowering the pollution of the environment, and isone of the main development directions in the future. At the same time, if the degumming technology is extensively applied into industrialization production, the dosage of enzymes will prodigiously increase, which will promote the development of the industry on enzymes.
