Mutants of Aspergillus aculeatus method for producing the same and production method of biomass derived products

摘要

The present invention relates to a biomass-derived useful product, and more particularly, to an Aspergillus aculeatus strain mutated to increase a yield of enzymes suitable for treating biomass and to a method for producing useful products derived from biomass using the strain. In the Aspergillus aculeatus mutant strain, creA gene or sequence number one and creB gene or sequence number two are all deleted.
