Supplementation of nitrogen and additional carbon
sources
Supplementation of different carbon sources to the medium
was also investigated by changing in medium using glucose,
xylose, starch, maltose, cellulose, galactose, sucrose or arabinose.
Highest yield of xylanase was found in case of xylose
(59.7 0.94 U/g) with protein content of 0.94 0.25 mg/ml as
compared to control. Low enzyme yield was recorded when
medium was supplemented with arabinose as shown in
Fig. 10. Isil and Nilufer (2005) studied some physiological
conditions affecting the xylanase production from T. harzianum
1073 D3. Their study indicated that xylose was found best
carbon source for xylanase production. Maximum production
of xylanase was observed in case of T. harzianum using
maltose and starch as carbon source
