  1. Increased production of free fatty acids in Aspergillus oryzae by disruption of a predicted acyl-CoA synthetase gene.

    Applied Microbiology and Biotechnology 99(7):3103 (2015) PMID 25564035

    Fatty acids are attractive molecules as source materials for the production of biodiesel fuel. Previously, we attained a 2.4-fold increase in fatty acid production by increasing the expression of fatty acid synthesis-related genes in Aspergillus oryzae. In this study, we achieved an additional i...
  2. Enhancing microbial metabolite and enzyme production: current strategies and challenges.

    Frontiers in Microbiology 5:718 (2014) PMID 25566228 PMCID PMC4270286

  3. Increased production of fatty acids and triglycerides in Aspergillus oryzae by enhancing expressions of fatty acid synthesis-related genes.

    Applied Microbiology and Biotechnology 97(1):269 (2013) PMID 22733113

    Microbial production of fats and oils is being developed as a means of converting biomass to biofuels. Here we investigate enhancing expression of enzymes involved in the production of fatty acids and triglycerides as a means to increase production of these compounds in Aspergillus oryzae. Exami...
  4. Comparative genome analysis between Aspergillus oryzae strains reveals close relationship between sites of mutation localization and regions of highly divergent genes among Aspergillus species.

    DNA Research 19(5):375 (2012) PMID 22912434 PMCID PMC3473370

    Aspergillus oryzae has been utilized for over 1000 years in Japan for the production of various traditional foods, and a large number of A. oryzae strains have been isolated and/or selected for the effective fermentation of food ingredients. Characteristics of genetic alterations among the strai...
  5. Characterization of the biosynthetic gene cluster for the ribosomally synthesized cyclic peptide ustiloxin B inAspergillus flavus

    Fungal Genetics and Biology 68 (2012) PMID 24841822

    • The entire gene cluster responsible for ustiloxin B biosynthesis was validated. • A ribosomal peptide synthesis (RiPS) pathway was first characterized in Ascomyc...
  6. Identification and characterization of genes responsible for biosynthesis of kojic acid, an industrially important compound from Aspergillus oryzae.

    Fungal Genetics and Biology 47(12):953 (2010) PMID 20849972

    Kojic acid is produced in large amounts by Aspergillus oryzae as a secondary metabolite and is widely used in the cosmetic industry. Glucose can be converted to kojic acid, perhaps by only a few steps, but no genes for the conversion have thus far been revealed. Using a DNA microarray, gene expr...
  7. Use of the Aspergillus oryzae actin gene promoter in a novel reporter system for exploring antifungal compounds and their target genes.

    Applied Microbiology and Biotechnology 87(5):1829 (2010) PMID 20464390

    Demand for novel antifungal drugs for medical and agricultural uses has been increasing because of the diversity of pathogenic fungi and the emergence of drug-resistant strains. Genomic resources for various living species, including pathogenic fungi, can be utilized to develop novel and effecti...

    Fungal Genetics and Biology 47(12):953 (2010) PMID 20849972

    Kojic acid is produced in large amounts by Aspergillus oryzae as a secondary metabolite and is widely used in the cosmetic industry. Glucose can be converted to kojic acid, perhaps by only a few steps, but no genes for the conversion have thus far been revealed. Using a DNA microarra...
  9. Genomics of industrial Aspergilli and comparison with toxigenic relatives.

    Food Additives & Contaminants: Part A - Chemist... 25(9):1147 (2008) PMID 18798040

    Aspergillus oryzae has been used in Japanese fermentation industries for more than a thousand years. The species produces large amounts of various hydrolytic enzymes and has been successfully applied to modern biotechnology. The size of the A. oryzae genome (37.5 Mb) is very close to that of A. ...
  10. Transcriptional regulation of genes on the non-syntenic blocks of Aspergillus oryzae and its functional relationship to solid-state cultivation.

    Fungal Genetics and Biology 45(2):139 (2008) PMID 17967552

    Transcriptome analysis revealed close relationship between solid-state cultivation and the transcriptional regulation of the genes on the non-syntenic blocks (NSBs), which were characterized by the comparison of Aspergillus oryzae genome with those of Aspergillus fumigatus and Aspergillus nidula...
