production by using T. viride. Xia and Cen (1999) reported that
30% substrate was best for cellulase accumulation. Reis,
Costa, and Peralta (2003) obtained maximum xylanase activity
(130 16 IU/ml) with 5% sugarcane bagasse as a carbon
source in submerged fermentation using Aspergillus nidulans.
Substrate concentration of 14% w/v bagasse produced
maximum xylanase activity of 27.6 U/ml using strain of T.
harzianum Rifai (Rezende et al., 2002). High concentration of
carbon sources inhibits the enzyme synthesis (Naidu & Panda
