Abstract: Degumming is a key problem in bast fibre industry while biological method is the development trend of fibre extraction, and pectinases application in biological degumming is the hotsopt of the research. In this paper, the mechanism of the pectinases used for bast fibre degumming has been expounded according to many studies on the pectinases and the pectinase-producing strains. Pectinase is considered as an essential enzyme for bast fibre bio-degumming, but it can not complete degumming independently. The research in the future will focus on constructing efficient strains, which secrete the whole indispensable enzymes by genetic manipulation methods.
