苎麻细菌脱胶菌种的筛选

SCREENING OF BACTERIAL STRAINS FOR DEGUMMING OF RAIME

从土壤中分离到两株苎麻脱胶细菌,均系芽孢杆菌,编号GT—17和Yt—2—7。GT—17能脱去原麻中95%以上的果胶、30—40%的半纤维素,总残胶约在10—11%。较目前国内报道的脱胶菌株T_(66)为优。

Two strains of Bacillus sp. capable of degumming of Ramie have been screened from soil.They are designated as GT-17 and Yt-2-7. Among them strain GT-17 is able to degrade more than 95% of protopectin and 30-40% of hemicellulose of Ramie. This strain shows higher activity to degum Ramie than the bacterical strain T_(60) reported by Sun Qingxiang.
