Of the two hemicellulosic substrates tested, bagasse was found to be the better inducer for xylanase production. Alkali treatment of bagasse and rice husk had varied effects on enzyme production. The enzyme preparation had activity optima at 60° C and 70° C and a half-life of 60 min at 65° C. The enzyme was stable for 24 h over a pH range of 4.0-6.0, while maximum activity was observed at pH 6.0-7.0. Enzyme production and activity were inhibited by the end-product of xylan hydrolysis, xylose.
