Hydrolysis of hemicellulose, esp. xylan(s) - using enzyme prepn. contg. endo-beta-xylanase I and/or endo-beta-xylanase II from Trichoderma reesei

摘要

A process is claimed for hydrolysing hemicelluloses, esp. xylans, in wood or fibres, or isolated from these, characterised by utilisation of an enzyme prepn. isolated from Trichoderma reesei, contg. an endo-beta-xylanase I with an pI value of 5.5 and a mol. wt. of 19 kD and/or an endo-beta-xylanase II with a pI value of 9 and a mol. wt. of 20 kD. The enzyme prepn. may also be produced by a strain derived by transferring the genes encoding T. reesei xylanases I and/or II to a host strain.
