A Thermostable Crude Endoglucanase Produced by Aspergillus fumigatus in a Novel Solid State Fermentation Process Using Isolated Free Water

Table 1

Activity profile of culture filtrates of A. fumigatus grown for one week under SSF_H2O conditions. The fermentation was carried out at 30^°C for 7 days under static conditions with manual shaking once a day.

Protein concentration	87 (±5.9) (μg/mL)
CMCase activity^*	868 (IU/mL)
Specific activity	9977 (IU/mg)
Activation energy^** (𝐸𝑎)	32.7 K J mole^−1
Temperature coefficients (𝑄10)	1.50 at 40^°C
	1.46 at 50^°C
	1.43 at 60^°C

^∗Enzyme activity was measured at 60^°C, that is, near to the optimum temperature of the enzymes, ^∗∗𝐸_𝑎 was calculated based on Figure 2.
