Production and characterization of xylanase from a Streptomyces species grown on agricultural wastes

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.
