First molecular report of causative agent of otomycosis due to Aspergillus luchuensis

Journal of Wound Care, 2021
Otomycosis is a fungal infection of the external auditory canal caused mainly by the genus Aspergillus. Aspergillus luchuensis, an industrially important fungus, is a member of Aspergillus section Nigri. In this report, we present a case of otomycosis due to Aspergillus luchuensis in a 43-year-old female patient.

Simultaneous detection of Aspergillus nidulans, Aspergillus luchuensis and Lichtheimia sp. in a bovine abortion

Journal de Mycologie Médicale, 2020
Abortion in dairy cattle may be caused by infectious (viruses, fungi and protozoa) and non-infectious causes mostly related to bad management practices and genetic factors. Recently, the significant contribution of mycotic infection to bovine abortion has been recognized.

Probiotic Potential, Antibacterial, and Antioxidant Capacity of Aspergillus luchuensis YZ-1 Isolated From Liubao Tea

Probiotics and Antimicrobial Proteins, 2023
Abstract Aspergillus fungi are widely used in the traditional fermentation of food products, so their safety risks and functions are worthy of investigation. In this study, one Aspergillus luchuensis YZ-1 isolated from Liubao tea was identified based on phylogenetic analyses of sequences of three genes coding for internal transcribed spacer 1 ...

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.

Expression of heterochromatin protein 1 affects citric acid production in Aspergillus luchuensis mut. kawachii

Journal of Bioscience and Bioengineering, 2023
A putative methyltransferase, LaeA, controls citric acid production through epigenetic regulation of the citrate exporter gene, cexA, in the white koji fungus Aspergillus luchuensis mut. kawachii. In this study, we investigated the role of another epigenetic regulator, heterochromatin protein 1, HepA, in citric acid production.

Identification and characterization of thermostable endo‐polygalacturonase II B from Aspergillus luchuensis

Journal of Food Biochemistry, 2020
Endo-polygalacturonase II B (PgaB) from Aspergillus luchuensis was orthologous to endo-polygalacturonase from Aspergillus niger with mutant sites Thr42Ser and Glu52Ala. Mature pgaB gene was cloned from the genomic DNA of A. luchuensis and secreted expressed with over 90% purity in Pichia Pastoris and reached 1.0 g/L after 144 hr culture.

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.

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.

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.
