A 150-litre pilot scale fermentation using Trichoderma reesei (RUT C-30) for the production of cellulase is described in which a cellulase yield of 12.0 IU.mlTl (filter paper activity) and productivity of 75 IU.LTlhTl were achieved.
## Sununary The plant growth regulators, indole-3-acetic acid (IAA) and gibberellit acid (GA3), were tested for their effects on spore germination and cellulase (B-1,4-endogluconase) production by Trichoderma reesei. The addition of 10 -5 M IAA or GA3 enhanced cellulase production, whereas higher
