Localisation of endo β‐1‐4‐xylan xylanohydrolase and β‐xylosidase was studied in Chaetomium globosum when the fungus was grown on 1% (w/v) birchwood xylan. Although both enzymes are present in the soluble fraction of the cell, xylanase activity was membrane bound whereas β‐xylosidase activity was associated with the cell wall. Xylanase and β‐xylosidase acted synergistically on the xylan backbone with the appearance of xylo‐oligosaccharides, xylobiose and xylose.
