Abstract
Xylan as the inducing substrate ,using ultrathin-layer agar plate diffusion technique and DNS assay and rescreening ,eventually screened 3 xylanase producing high strains from 66 edible fungus in liq-uid fermentation induced culture .Black fungus LK8 ,Yutian mushroom ,M ushroom 236 have better en-zyme production capacity ,detection of single factor combined with orthogonal experiment finalized train-ing time ,pH and xylan concentration as the optimal condition for xylanase production were 20 d ,7 .5 and 1 .0 g/100mL ;25 d ,7 .0 and 1 .0 g/100mL ;25 d ,5 .0 and 0 .75 g/100mL ,respectively .Xylanase activi-ty under optimum conditions were :600 .6 IU/mL ,672 .5 IU/mL ,345 IU/mL .The culture solution pH value is the main factor affecting the induction effect .关键词
