Enhanced Production of Cellulase-free Xylanase by Alkalophilic Bacillus Subtilis Ash and Its Application in Biobleaching of Kraft Pulp
This paper reports high level production of a cellulase-free xylanase using wheat bran, a cost-effective substrate, under submerged fermentation by alkalophilic Bacillus subtilis ASH. Production of xylanase was observed even at alkaline pH up to 11.0 and temperature 60 °C, although the highest enzyme titer was recorded at neutral pH and 37 °C. The enzyme production under optimized fermentation ...
