The Components and Activities of Flax-Degumming Enzymes Produced by Bacillus licheniformis HDYM-03
Abstract:
Bacillus licheniformis HDYM-03 was isolated from flax-retting water. In this research, the production of flax-degumming enzymes by this strain was investigated in four medium, whose sole carbon source was beef extract peptone (BP), pectin (PEC), konjac powder (KGM) and carboxymethylcellulose sodium (CMC), respectively. In PEC medium, the production of pectinase (455.06 U/mL) and polygalacturonase (540.32 U/mL) is higher than that in other medium. In KGM medium, the mannanase reach the highest activity 193.33 U/mL. The production of xylanase and cellulase is extremely lower and could be ignored in all of the four medium. The results show that the production of flax-degumming enzymes by this strain could be significantly induced by flax colloid. B.licheniformis HDYM-03 suggest an applicable potential in flax-retting industry.
