FPase activities of T. reesei TU-6 and TU6-vgb⁺ in different culture volumes

Culture volume (ml)/250 ml	FPU		Increasing rate
	TU-6	TU6-vgb+
50	0.78 (± 0.036)	0.78 (± 0.062)	0
80	0.43 (± 0.131)	0.52 (± 0.063)	21%
100	0.19 (± 0.013)	0.30 (± 0.001)	58%

All cultures were grown in 250 ml flasks with different volumes (50, 80 and 100 ml) of cellulase-inducing medium. Data represented are the means of three independent cultures, SD are given in brackets
