Abstract: | The xylanolytic system from Cellulomonas flavigena was enhanced by adding cellulose to the growth medium. The Solka floc:xylan (60:40 w/w) mixture induced xylanase synthesis by more than 3-fold over that induced by growing C. flavigena, wild type and its mutant PN-120 on pure xylan. The hydrolysis pattern of sugar cane bagasse and xylan indicated the presence of debranching endo-;-xylanase activity. |
