Abstract
A strain producing xylanase was screened and identified as Bacillus sp.HSⅠ.The medium was composed of bran 6% ,(NH 4) 2SO 4 0.2%, NaNO 3 0.4% and peptone 0.6% .The optimum conditions for producing xylanase were initial pH 10.5,seed volume 5% and temperature 37℃.The fermentation time was 96h and the highest xylanase activity of 54IU/mL was obtained.
