GENETICALLY ENGINEERED E. COLI EXPRESSING XYLANASE ENZYME

摘要

This invention relates to an improved xylanase production by recombinant E. coli cells. Xylanase gene was isolated from Bacillus brevis, inserted into pET29a vector and expressed successfully in E. coli DH5a. The xylanase expression by transformed E. coli is found much better than the native Bacillus brevis strain and the xylanase enzyme is secreted directly into the medium. This improved production will reduce the cost of enzyme production at the commercial level.
