Effect of additional carbon source and moisture level on xylanase production by Cochliobolus sativus in solid fermentation

摘要

The fungus Cochliobolus sativus has been shown to be an efficient producer of xylanase from an industrial point of view. The addition of extra carbon sources and the initial moisture content of the solid-state fermentation were found to have a marked influence on the xylanase production by C. sativus Cs6 strain. Xylan and starch resulted in an increased xylanase production (1469. 4 and 1396. 56 U/g, respectively) after 8 days of incubation. Optimal initial moisture content for xylanase production was 80%. The cultivation systems can easily be modified to enhance the productivity of the enzyme formation by C. sativus Cs6, which will facilitate the scale up processes for mass production.
