Xylanase is an important enzyme, required in many industries to degrade xylan. A local xylanolytic bacteria, producer of xylanase enzyme has been screened and isolated from a liquid fermentation broth of organic waste. The bacteria was identified as Pseudomonas stutzeri species and showed high xylanolytic activity. In the medium with 2 % (w/v) birchwood xylan and temperature of 37°C, the bacteria produced optimally xylanase enzyme for time of 27 hours, by adding of 0.5 % (w/v) molasses. The yielded xylanase could work optimally at pH 5 and temperature of 50°C. This finding underlies the development of xylanase production on a large scale, using the bacteria in the future.
