Notes:
Intracellular concentrations of ATP, cyclic AMP and glucose-6-phosphate were monitored during growth of partially catabolically derepressed strain of Trichoderma reesei CC II in medium containing lactose as the sole carbon source. The induction of cellulase synthesis occured when the concentration of lactose in the medium decreased below 7 mg/ml. The onset of cellulase synthesis was preceded by a transient peak of intracellular concentration of ATP and by the increase of the cyclic AMP contents in the mycelium whereby the intracellular level of glucose-6-phosphate was at its minimum. By keeping the lactose concentration in the medium at 2 mg/ml, it was possible to support the continuation of cellulase synthesis over the prolonged periods without appreciable growth of biomass.
