Process for preparing pectinase for degumming ramie and its application in degumming ramie

A pectinase for degumming remie is prepared through naturally sampling bacteria, measuring its enzyme activity by Nelson Somogyi method, and sceening the bacteria. It is Bacillus subtilis (CCTCC0 No.M200038). Its advantages are simple culture condition, high growth and reproduction speed, and high a...

Zusammenfassung:	A pectinase for degumming remie is prepared through naturally sampling bacteria, measuring its enzyme activity by Nelson Somogyi method, and sceening the bacteria. It is Bacillus subtilis (CCTCC0 No.M200038). Its advantages are simple culture condition, high growth and reproduction speed, and high activity to generate pectinase. Its fermenting liquid can be directly used to degum the ramie with short period (2-4 hr), high degamming rate (97.5-98.5% and no damage to fibres.
