Title:
METHOD FOR PRODUCING β-GLUCANASE AND XYLANASE USING SPENT GRAINS AND LIQUID MEDIUM
Document Type and Number:
WIPO Patent Application WO/2010/116545
Kind Code:
A1
Abstract:
To produce a cellulase, which has an excellent ability to degrade a cellulose resource containing xylan, at a low cost. A method for producing β-glucanase and xylanase which comprises a step of culturing a microorganism belonging to the genus Trichoderma with the use of a liquid medium containing (a) spent grains as a carbon source and (b) ammonia nitrogen or amino nitrogen as a nitrogen source.
