MICROBIALLY EXPRESSED XYLANASES AND THEIR USE AS FEED ADDITIVES AND OTHER USES.

摘要

The present invention relates to codon-optimized xylanase coding sequences andthe expression of xylanases in microbes and yeast. The invention further relatesto using multiple copies of the xylanase expression construct for high levelsof protein expression. The invention also relates to the use of xylanases as feedor food additives. The invention also relates to methods of expression of enzymesto increase thermotolerance by expressing them in organisms that glycolsylateproteins compared to expression that the same enzyme without the glycosylation.Further, the invention relates to methods of preparing feed, enzyme feed additives,and methods of reducing the feed conversion ration or increasing weight gainof animals.
