Screeningand fermentation conditions of xylanase-producing white rot fungi

A strain of xylanase producing was screened from white-rot fungi.The fermentation of the xylanase was studied.A xylanase producing strain was isolated from the preservation of white-rot fungi.The fermentation conditions of xylanase by the strain are optimized in the study through the single factor and the orthogonal experiment.So the best conditions are: 2.5% wheat bran + 2.5% corn cob,0.5% peptone,4 pieces per 50mL liquid volume,8.5d,and start pH value 5.4.The optimized fermentation conditions improved significantly strains production xylanase activity.
