Evaluation of catalase activity of clinical and environmental isolates of Aspergillus species

open access: yesIranian Journal of Microbiology, 2022
Background and Objectives: Catalases are a good scavenger of H2O2 which degrades hydrogen peroxide into water and oxygen. They are considered as a virulence factor that are present in both spores and hypha of fungi.

Formation of sclerotia and production of indoloterpenes by Aspergillus niger and other species in section Nigri. [PDF]

open access: yesPLoS ONE, 2014
Several species in Aspergillus section Nigri have been reported to produce sclerotia on well-known growth media, such as Czapek yeast autolysate (CYA) agar, with sclerotia considered to be an important prerequisite for sexual development.

Activity of essential oils from Syzygium aromaticum and Rosmarinus officinalis against growth and ochratoxin A production by Aspergillus tubingensis and Aspergillus luchuensis from Moroccan grapes

open access: yesPhytopathologia Mediterranea, 2022
Essential oils have been used since ancient times in traditional medicine and agri-food science to preserve food, and to combat human diseases. Essential oils (EOs) from clove and rosemary, obtained by hydro-distillation, were analyzed by GC/MS and ...

Development of an itraconazole resistance gene as a dominant selectable marker for transformation in Aspergillus oryzae and Aspergillus luchuensis

open access: yesBioscience, Biotechnology, and Biochemistry, 2021
ABSTRACT There are only a few combinations of antifungal drugs with known resistance marker genes in the Aspergillus species; therefore, the transformation of their wild-type strains is limited. In this study, to develop the novel dominant selectable marker for itraconazole, a fungal cell membrane synthesis inhibitor, we focused on ...

Construction of transcription factor gene deletion library of Aspergillus luchuensis.

open access: yesThe Journal of general and applied microbiology, 2021
We selected 96 genes of Aspergillus luchuensis for the construction of a transcription factor gene deletion library. Of these, we successfully deleted 93 genes using Agrobacterium-mediated transformation (AMT) of A. luchuensis RIB 2604 ΔligD strains.

Removal of pharmaceutical compounds from municipal wastewater by bioaugmentation with fungi: An emerging strategy using fluidized bed pelleted bioreactor

open access: yesEnvironmental Advances, 2021
Fungi have been shown to be good candidates to remove pharmaceuticals. However, the pilot-scale application mainly deals with the strict growth conditions and competition between microbial communities from wastewater.

The white koji fungusAspergillus luchuensismut.kawachii

open access: yesBioscience, Biotechnology, and Biochemistry, 2022
ABSTRACTThe white koji fungus, Aspergillus luchuensis mut. kawachii, is used in the production of shochu, a traditional Japanese distilled spirit. White koji fungus plays an important role in the shochu production process by supplying amylolytic enzymes such as α-amylase and glucoamylase.

Insights regarding sirtuin-dependent gene regulation during white koji production

open access: yesCommunicative & Integrative Biology, 2022
White koji, a solid-state culture of Aspergillus luchuensis mut. kawachii using grains such as rice and barley, is used as a source of amylolytic enzymes and citric acid for the production of shochu, a traditional Japanese distilled spirit. We previously

Effects of Amazake Produced with Different Aspergillus on Gut Barrier and Microbiota

open access: yesFoods, 2023
Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract. To explore the preventive effects of dietary foods on IBD, we evaluated the effects of the traditional Japanese fermented beverage “Amazake” on gut barrier ...
