摘要: 为改进苎麻脱胶工艺,采用选择平板初筛,脱胶发酵实验复筛,从60 株保藏菌种中筛选得到可用于苎麻微生物脱胶的优良菌种———An6。在以未经刮制的苎麻韧皮为主要碳源,015 %(NH4 ) 2 SO4 为氮源,添加0105 % MgSO4 ,0105 %KCl ,011 %K2HPO4 ,01001 %FeSO4 的培养液中,接入An6 ,置30 ℃下150 rPmin处理40 h左右,脱胶麻残胶率为15193 %。

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 %.
