Disruption of the L-arabitol dehydrogenase encoding gene in Aspergillus tubingensis results in increased xylanase production.

Abstract excerpt

Fungal xylanases are of major importance to many industrial sectors, such as food and feed, paper and pulp, and biofuels. Improving their production is therefore highly relevant. We determined the molecular basis of an improved xylanase-producing strain of Aspergillus tubingensis that was generated by UV mutagenesis in an industrial strain improvement program. Using enzyme assays, gene expression, sequencing of...
