| 摘 要： | 利用丙酮分级沉淀的方法,将Bacillus sp. No.16A发酵液中的果胶酶和甘露聚糖酶处理成不同活性比例的3组脱胶酶液.分别进行苎麻脱胶后,分析了纤维的一些特征,包括:手感柔软程度、纤维分散程度、果胶残留、失重率、纤维细度及扫描电镜图.通过比较发现,甘露聚糖酶对果胶酶的脱胶效果有一定的协同作用,前者能增强后者的脱胶效果.

| Abstract: | The cell free culture supernatant of Bacillus sp. No.16A was treated by acetone into three groups of degumming liquor with different compositions of pectinase and β mannanase. Their degumming effects were investigated by analyzing some of the fibers' characters, including softness, dispersal degree, residual gum, weight lost, fineness and SEM photograph. The results show that β mannanase has certain synergetic function on pectinase in ramie degumming, namely, the β mannanase can improve the degumming effect of pectinase. |

| Keywords: | biodegumming synergetic action pectinase β mannanase |
