The Aspergillus oryzae xynF1 gene coding for a xylanase, XynF1, was successfully overexpressed under the strong A. oryzae TEF1 gene promoter. The high-XynF1-producing transformant secreted about 180 mg/l of XynF1 in the glucose-containing medium. The overexpressed XynF1 was purified by only one chromatographic step. The purified XynF1 had a molecular mass of 35.0 kDa, a pH optimum of 5.0, and a temperature optimum of 60 degrees C. |
