5.19±0.08 U ml− 1 when cultured in a production medium containing 3.89%(w/v) rice straw
and 0.75%(w/v) NaNO 3 as carbon and nitrogen sources, respectively, for 72 h. This enzyme
catalyzed well and was relatively stable at pH 7.0 and room temperature (28±2° C). The
produced xylanase was used to hydrolyze xylans from four tropical weeds, whereupon it
was found that the highest amounts of reducing sugars in the xylan hydrolysates of cogon …
