Different temperature profiles of enzyme secretion by two common strains of Trichoderma reesei

We have investigated the effects of high and low temperature on the synthesis and secretion of cellulases and other enzymes by two common and readily available strains of Trichoderma reesei . While some effects were similar in both strains QM9414 and RUT-C30 (a reduction in cellulase production but...

Zusammenfassung:	We have investigated the effects of high and low temperature on the synthesis and secretion of cellulases and other enzymes by two common and readily available strains of Trichoderma reesei . While some effects were similar in both strains QM9414 and RUT-C30 (a reduction in cellulase production but stimulation of xylanase production at high temperature, and alterations in expression of the cellulase complex at low temperature), some specific differences between the strains were determined, most significantly an enhanced specific secretion rate (secretion/growth) at low growth temperature for QM9414.
