An aureobasidin A resistance gene isolated from Aspergillus is a homolog of yeast AUR1, a gene responsible for inositol phosphorylceramide (IPC) synthase activity.

We report the molecular cloning and characterization of the Aspergillus nidulans aurA gene, which is homologous to AUR1. A single point mutation in the aurA gene of A. nidulans confers a high level of resistance toaureobasidin A. The A. nidulans aurA gene was used to identify its homologs in other Aspergillus species, including A. fumigatus, A.

Sequence analysis indicated that the enzyme Af-EGL7 belonged to the GH7 family. The gene Af-egl7 encoded a protein comprising 460 amino acids, with a CBM1 domain at residue...

r Ulrike Binder Mucorales are fungi with increasing importance in the clinics. Infections take a rapidly progressive course resulting in high mortality rates. The ergosterol biosynthesis pathway and sterol composition are of interest, since they are targeted by currently applied antifungal drugs. Nevertheless, Mucorales often exhibit resistance to these drugs, resulting in therapeutic failure. Here, sterol patterns of six clinically relevant Mucorales (Lichtheimia corymbifera, Lichtheimia ramosa, Mucor circinelloides, Rhizomucor pusillus, Rhizopus arrhizus, and Rhizopus microsporus) were analysed in a targeted metabo...

Publication date: Available online 18 May 2018 Source:Current Opinion in Food Science Author(s): Marta Hiromi Taniwaki, John I. Pitt, Naresh Magan Aspergillus species produce important mycotoxins, in particular aflatoxins, produced by A. flavus and related species, and ochratoxin A, produced by A. ochraceus and related species and also A. carbonarius and (less commonly) A. niger. In this review we briefly discuss the distribution of toxigenic Aspergillus species in nuts, coffee and cocoa beans, dried fruits, grapes, maize, rice and small grains. Future perspectives of distribution of Aspergillus species in foods is briefl...

This study investigated volatile and nonvolatile metabolite profiles of makgeolli (a traditional rice wine in Korea) fermented by koji inoculated with Saccharomycopsis fibuligera and/or Aspergillus oryzae. The enzyme activities in koji were also examined to determine their effects on the formation of metabolites. The contents of all 18 amino acids detected were the highest in makgeolli fermented by S. fibuligera CN2601-09, and increased after combining with A. oryzae CN1102-08, unlike the contents of most fatty acids. On the other hand, major volatile metabolites were fusel alcohols, acetate esters, and ethyl esters. The c...

To this end, physical immobilization by hydrophobic interactions was performed with three well-characterized cutinases (Aspergillus oryzae Cutinase (AoC), Humicola insolens Cutinase (HiC), and Thielavia terrestris Cutinase (TtC)) using Lewatit VP OC 1600 as the macroporous...
