Production of alkaliphilic, halotolerent, thermostable cellulase free xylanase by Bacillus halodurans PPKS-2 using agro waste: single step purification and characterization.

The alkaliphilic Bacillus halodurans strain PPKS-2 was shown to produce extracellular alkaliphilic, thermostable and halotolerent xylanase. The culture conditions for xylanase production were optimized with respect to pH, temperature, NaCl and inexpensive agro waste as substrates. Xylanase yield was enhanced more than four fold in the presence of 1% corn husk and 0.
