微生物快速脱胶法在温水沤麻中的应用研究

Application of fast degumming with bacteria on retting flax

以果胶酶产生菌HDYM-01和HDYM-02为出发菌株,经扩大培养后加入到沤麻池中进行温水沤麻试验。试验结果表明加菌沤麻工艺出麻率较正常沤制高,进行F检验证明差异极显著。利用加菌沤麻所得沤麻水进行回用沤麻试验,结果表明加菌沤麻水回用工艺出麻率较正常沤制高,经F检验差异显著。两项工艺均可使沤麻时间缩短24h,提高强度20～30N(牛顿)。

Two pectinase -producing strains HDYM -01 and HDYM -02, which were amplified in liquid medium, were added into tank retting to proceed water - retting. The results showed that the yield of fiber flax was significant higher with adding bacteria technology than that of with normal technology. When reusing retting water to proceed the next flax retting, the yield of fiber flax was higher and the difference was also significant with F test. The time for retting flax would be shortened for 24h using the technologies and raise the strength of flax for 20 - 30 N.
