A rapid process of ramie bio-degumming by Pectobacterium sp CXJZU-120

Factory tests for rapid process of ramie bio-degumming by Pectobacterium sp. CXJZU-120 were conducted and evaluated comparing the processes of traditional chemical degumming and bio-chemical degumming. Results revealed that over 90% of the gum in raw ramie could be removed only with Pectobacterium sp. CXJZU-120 in 6 h. The rapid process was not only suitable for the extraction of ramie fibers from different grades of raw material and retaining the inherent morphological structures and textile properties, but also could reduce the production cost up to 20.5%, raise resource utilization by more than 50% and reduce pollution charge by more than 80% compared with the traditional chemical degumming. It is a breakthrough in the degumming of ramie and has great application potential in the extraction of herbaceous fiber materials.
