After pretreatment, cellulase production was conducted in 250ml Erlenmeyer flask at 50 ºC, pH 5 with shaking speed of 120 rpm using 2% pretreated eucalyptus leaves as carbon source and 2% v/v inoculum size in submerged fermentation for 24h. Results showed that among these two treatments, only chemical treated substrates gave better enzyme yield as compared to chemical followed by steam.

Fsd- and Swl-strains exhibited increased activities of amylases with Vmax value of 2.68 and 1.89 µM s-1 respectively and Km value of 23.8 g L-1 and 40.1 g L-1, respectively. These findings suggest that the increased activities of cellulases and amylases...
