Production and Characterization of Xylanase from Aspergillusparasiticus URM 5963 Isolated from Soil of Caatinga

Filamentous fungi, Aspergillus parasiticus URM 5963 was biochemically selected among different species of Aspergillus, for xylanase production. The enzyme activity and specific activity of partially purified xylanase from Aspergillus parasiticus URM 5963 was 1,116 IU/ml and 6,245 IU/mL, respectively. Temperature and optimum pH for xylanase were found to be 50°C and 5.5, respectively. Of the many reported applications for xylanase, its use as a food supplement has played an important role for monogastric animals, because it can improve the utilisation of nutrients. In this work an effort has been made in order to increase available knowledge about a xylanase produced by submerged cultivation from Aspergillus parasiticus URM 5963 and partial characterization
