CMCase activities and specific enzyme activities at the optimal working condition of crude cellulases produced from CBD2 and CBD3 and commercial Celluclast 1.5 L.

Enzyme	Optimal Condition	Enzyme Activity (U/mL)	Specific Enzyme Activity (U/mg)
CBD2	pH 7, 55 °C	0.62 ± 0.023 c	0.20 ± 0.014 C
CBD3	pH 5, 50 °C	0.73 ± 0.017 b	0.22 ± 0.018 B
Celluclast 1.5 L	pH 5, 50 °C	4.20 ± 0.033 a	0.32 ± 0.025 A

The represented data are the mean of three replicates ± standard error (p ≤ 0.05). ^{a, b, c} determine statistically difference in enzyme activities. ^{A, B, C} determine statistically difference in specific enzyme activities.
