The beta-(1,4)-linked xylose residues that comprise the backbone of the abundant plant polymer xylan can be released by enzymic hydrolysis. Xylanase, which is produced in exceptionally high levels by the color-variant strain of A. pullulans, was immobilized onto a macroporous ceramic carrier. Despite a low coupling efficiency, it was possible to run the reactor under a wide range of conditions with flow rates of 3-10 bed volumes/minute of 1% soluble xylan with no detectable leaching of enzyme. The size distribution of products and rate of xylan hydrolysis were very similar for the immobilized and soluble enzymes. (Refs. 13).
