Abstract

Methods and expression constructs are provided for the cloning of genes from fungal origin which encode polypeptides having xylanase activity and their overexpression in a selected microbial host cell. Xylanases of fungal origin generally have lower pH optima and remain stable over a broader pH range than do xylanases of bacterial origin. The present invention provides for the high level production of fungal xylanases which are may be used in a variety of industrial applications requiring xylanase activity at a low pH
