About Aureobasidium subglaciale EXF-2481 (GCA_000721755)

Aureobasidium subglaciale, formerly known as Aureobasidium pullulans var. subglaciale, is a ubiquitous black, yeast-like fungus that is found in very cold habitats. As the name suggests, it was primarily isolated from subglacial ice of arctic glaciers.

The genome of A. subglaciale (as well as other closely related species) contains unusually high numbers of genes for extracellular enzymes for carbohydrate degradation (CAZy) and proteases, MFS membrane sugar transporters, and alkali metal cation transporters (or ion transporters). Genes presumably involved in the synthesis of the biotechnologically important polysaccharide pullulan and siderophores were found, but the gene for antibiotic Aureobasidin A could not be identified. Genes possibly associated with the degradation of plastic and aromatic compounds are also present.

Due to the relatively recent redefinition of the species, most published work does not yet distinguish between the new species belonging to the previously recognised A. pullulans species complex. It is therefore not clear to what extent this knowledge is valid for A. subglaciale.
