In this study, new gene sources for the production of xylanase enzyme, which occupies a large area in industrial and biotechnological field, were investigated and optimization of production conditions was aimed to increase enzyme production efficiency. For this reason, the techniques of solid state fermentation and submerged fermentation were compared, the initial inoculation type and amount were optimized and the effect of humidification rate on the efficiency of enzyme production was determined. From 49 Actinomycetes strains isolated from soil, it was determined that xylanase production from Streptomyces TEM 25, which was identified as the best xylanase producer, was best performed in solid culture fermentation using wheat bran. After the optimization of the solid state fermentation conditions, xylanase activity was increased 1.5 fold to 45.85 ±1.22 U/g wheat bran under 66.6% moistened conditions. The specific activity of the partially purified enzyme was increased 5-fold by the ammonium sulfate precipitation method.
