Abstract:
A xylanase producing strain was screened with xylan as the only carbon source. The strain was identified as Streptomyces cirratus. The effects of different factore on the enzyme production were studied. Corncobs xylan (water insoluble) and tryptone were the best C and N sources, respectively. The enzyme activity was increased to about 2.5 times by addition of 0.5% Tween 80 in the medium. The highest xylanase activity was up to 623u/mL.
