Characterization and induction of phenolic acid decarboxylase from Aspergillus luchuensis

Journal of Bioscience and Bioengineering, 2018
Awamori is a traditional distilled liquor in the Ryukyu Islands, made from steamed rice by the action of the black-koji mold Aspergillus luchuensis and awamori yeast Saccharomyces cerevisiae. One of the specific flavors in aged awamori kusu is vanillin, which is derived from ferulic acid (FA) in rice grains.

Identification and characterization of a thermostable pectate lyase from Aspergillus luchuensis var. saitoi

Food Chemistry, 2019
Pectinolytic enzymes are used in diverse industrial applications. We sought to isolate a pectate lyase from Aspergillus luchuensis var. saitoi, a filamentous fungus used in traditional food and beverage preparation in Japan. The identified enzyme, named AsPelA, is orthologous to PelA from A. luchuensis mut.

Citrate exporter enhances both extracellular and intracellular citric acid accumulation in the koji fungi Aspergillus luchuensis mut. kawachii and Aspergillus oryzae

Journal of Bioscience and Bioengineering, 2021
Citrate exporter CexA plays a key role in the production of citric acid in fungi; however, its role in intracellular metabolism has remained unclear. In this study, we comparably characterized homologous cexA genes in the white koji fungus Aspergillus luchuensis mut.

Effect of pepA deletion and overexpression in Aspergillus luchuensis on sweet potato shochu brewing

Journal of Bioscience and Bioengineering, 2019
The mash of sweet potato shochu (Japanese distilled spirit) has a low pH value because the shochu koji mold produces a large amount of citric acid, which prevents germ contamination. In this study, we examined acid protease PepA's role in shochu production.

Adsorptive removal of aflatoxin B1 via spore protein from Aspergillus luchuensis YZ-1

Journal of Hazardous Materials
Aflatoxin B1 (AFB1) is the most toxic mycotoxin commonly found in the environment. Finding efficient and environmentally friendly ways to remove AFB1 is critical. In this study, Aspergillus luchuensis YZ-1 demonstrated a potent ability to adsorb AFB1 for the first time, and the binding of AFB1 to YZ-1 is highly stable.

Aspergillus luchuensis fatty acid oxygenase ppoC is necessary for 1-octen-3-ol biosynthesis in rice koji

Journal of Bioscience and Bioengineering, 2020
Awamori is a distilled spirit produced in Okinawa Prefecture, in southern Japan. Awamori contains the volatile organic compound 1-octen-3-ol, an important flavor component. Here, using solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GCMS), we demonstrate that the black koji mold Aspergillus luchuensis produces 1-octen-3-ol in ...

Diketopiperazines and 2H-pyran-2-ones with antioxidant activity from the rice fermented with Aspergillus luchuensis

Fitoterapia, 2018
Aspergillus luchuensis is widely used as a starter of saccharification in the koji industry, but no secondary metabolites have been reported from this fungus. Herein, we report the isolation and identification of four new diketopiperazine derivatives (1-4), one new methyl 4-(3-acetyl-2, 6-dihydroxyphenyl)-2-methoxybutanoate (5), and six known compounds

Influence of α-1,3-glucan synthase gene agsE on protoplast formation for transformation of Aspergillus luchuensis

Journal of Bioscience and Bioengineering, 2019
Aspergillus luchuensis NBRC4314 recently underwent genome sequencing. We have not used the frequently used protoplast-polyethylene glycol (PEG) method but have used agrobacterium-mediated transformation (AMT) to genetically engineer this strain because it was difficult to generate protoplasts using commercial cell wall lytic enzymes.
