Neisseria gonorrhoeae that can be used for the production of seasonings lacking the function of the gene encoding creC and use thereof

摘要

PPROBLEM TO BE SOLVED: To provide Aspergillus oryzae strain having high activity of each kind of enzyme essential for the production of seasoning, and suitable for brewing. PSOLUTION: The Aspergillus oryzae strain having not only improved protease activities but also improved amylase activity and xylanase activity achieving important functions at the brewing as well as the above, and extremely suitable for the brewing can be created by causing defects of creC gene in the Aspergillus oryzae usually used in the production of the seasoning. The strain can be applicable for the production of a liquid malt, the production of a hydrolase usable at the saccharification step of bioethanol production, or the like easily receiving the influence of carbon catabolite repression because the deficiency of the creC gene is considered to relate the disinhibition of the carbon catabolite repression.
