Trichoderma sp. K9301 secreting endoxylanases with an activity of 2836 U/g (dry weight) was screened for XOs production. Two acidic b-endoxylanases EX1 (30.1 kDa) and EX2 (20.1 kDa) were purified from crude extract of the strain K9301 in solid fermentation. Action modes of EX1 and EX2 towards XOs sh...
