Studies on Regulation of Xylanase Bio-Synthesis by Trichoderma reesei SAF3
Subscribe/Renew Journal
Microbial xylanases have an exciting potentiality and are being used extensively in different industries. In this study, regulation of xylanase bio-synthesis was examined in Trichoderma reesei SAF3. Xylan (1.0% w/v) showed the highest inductive effect. Glucose at concentration of 1% (w/v) was repressive for xylanase bio-synthesis when used in presence or absences of xylan; the repression was partially elevated by addition of cyclic adenosine monophosphate (cAMP, 5mM). The above findings suggested that xylan was the major inducer and the induction was energy dependent, mediated by second messenger system.
