✦ Synopsis

Cyathus stercoreus grown on wheat straw had a higher xylanase activity than when it was grown on rice husk or extracted hemicellulose. Inclusion of casein hydrolysate, Tween 80 and Mn ~÷ (at 0.02%, 0.2% and 0.075%, respectively) increased the production of extracellular xylanase. Optimal yield of xylanase (0.73 U/ml) was at pH 5.6 after 9 to 12 days at 30°C. The xylanase was stable at pH 4.5 to 7.5 for 2h but above 50°C its stability fell sharply.

Alkali-treated corn stalk gave maximum xylanase production at supporting growth of Streptomyces HM-15. Xylanase was stable for 24 h over a pH range of 5.0 to 7.0, had optimal activity between 50 and 60°C and a halflife of 5 h at 60°C. Xylanase production and activity were inhibited by xylose.
