Study on Some Properties of Xylanase from Aspergillus usamii

WU Min-chen

Abstract

The xylanase production was investigated with solid fermentation by Aspergillus usamii. Xylanase activity reached 7442 IU/g dry medium under the optimized conditions at 28℃ for 72 h. The enzyme show an optimum temperature and pHof 50℃ and pH4.6 respectively. Xylanase was stable below 50℃ and within pH 5.0-10.0. Its activity was increased by Ca2+and strongly inhibited by Mn2+,Mg2+ and Ba2+.
