The use of canola meal as a substrate for xylanase production by Trichoderma reesei

Summary Tests made utilizing canola meal as a substrate for the production of xylanase indicate that Trichoderma reesei produced this enzyme in similar or better yields from canola meal than from Solka-floc, xylan or glucose. The maximum xylanase activity obtained from canola meal was 210 IU/ml in 9–12 days. The enzyme system produced using canola meal also contained a higher proportion of acetyl-xylan esterase, cellulase, and xylosidase activities. This system was more than or equally efficient as that produced using Solka-floc in hydrolysing canola meal, corn cobs, corn and wheat brans, straw, and larchwood xylan to fermentable sugars.Offprint requests to: Z.
