Abstract: In order to improve degumming process of ramie , a fine strain An6 suitable for degumming of
ramie was selected from the collected 60 strains by preliminary selection and repeated selection. An6 was
inoculated in the medium containing unprocessed ramie bast as carbon source and 015 % (NH4 ) 2 SO4 as
nitrogen source , added with 0105 %MgSO4 , 0105 %KCl , 011 %K2 HPO4 , 01001 %FeSO4 . Then , it was put
into a shaker at 150 rPmin 30 ℃for 40 h. The results indicated that the residual gum content was only
15193 %.
