Aureobasidium is omnipresent and can be isolated from air, water bodies, soil, wood, and other plant materials, as well as inorganic materials such as rocks and marble. A total of 32 species of this fungal genus have been identified at the level of DNA, of which Aureobasidium pullulans is best known. Aureobasidium is of interest for a sustainable economy because it can be used to produce a wide variety of compounds, including enzymes, polysaccharides, and biosurfactants. Moreover, it can be used to promote plant growth and protect wood and crops. To this end, Aureobasidium cells adhere to wood or plants by producing extracellular polysaccharides, thereby forming a biofilm. This biofilm provides a sustainable alternative to petrol-based coatings and toxic chemicals. This and the fact that Aureobasidium biofilms have the potential of self-repair make them a potential engineered living material avant la lettre. Key points •Aureobasidium produces products of interest to the industry •Aureobasidium can stimulate plant growth and protect crops •Biofinish of A. pullulans is a sustainable alternative to petrol-based coatings •Aureobasidium biofilms have the potential to function as engineered living materials

“…Notes-This species is phylogenetically close to A. aerium, A. intercalariosporum, A. leucospermi, and A. khasianum. These five species can be distinguished by the sizes of conidia (4.2-7.4 × 1.7-3.5 µm in A. insectorum, vs. 12.8-19.5 × 7.9-11.9 µm in A. aerium, vs. 8-13 × 5-9/8-24 × 2-10 µm in A. leucosperm, vs. 3-4 × 2-40 µm in A. khasianum, vs. 10.5-17.1 × 10.5-12.9 µm in A. intercalariosporum) [11,12,40]. Colonies grew moderately on PDA, MEA, and OA (Figure 2), attaining 22 mm, 24 mm, and 30 mm diameters after 7 days of incubation at 25 °C, respectively.…”

In this study, 99 strains of Aureobasidium species were isolated from various samples collected from different locations in China, among which 14 isolates showed different morphological characteristics to other strains identified as known Aureobasidium species. Based on morphological characteristics, those 14 strains were classified into four groups, represented by stains of KCL139, MDSC−10, XZY411−4, and MQL9−100, respectively. Molecular analysis of the internal transcriptional spacer (ITS) and part of the large ribosome subunit (D1/D2 domains) indicated that those four groups represent four new species in the Aureobasidium. Therefore, the names Aureobasidium insectorum sp. nov., A. planticola sp. nov., A. motuoense sp. nov., and A. intercalariosporum sp. nov. are proposed for KCL139, MDSC−10, XZY411−4, and MQL9−100, respectively. We also found that there were differences in the yield of exopolysaccharides (EPS) among and within species, indicating strain-related exopolysaccharide-producing diversity.

Purpose This study aimed to look insights into taxonomy, evolution, and biotechnological potentials of a yeast-like fungal strain P6 isolated from a mangrove ecosystem. Methods The genome sequencing for the yeast-like fungal strain P6 was conducted on a Hiseq sequencing platform, and the genomic characteristics and annotations were analyzed. The central metabolism and gluconate biosynthesis pathway were studied through the genome sequence data by using the GO, KOG, and KEGG databases. The secondary metabolite potentials were also evaluated. Results The whole genome size of the P6 strain was 25.41Mb and the G + C content of its genome was 50.69%. Totally, 6098 protein-coding genes and 264 non-coding RNA genes were predicted. The annotation results showed that the yeast-like fungal strain P6 had complete metabolic pathways of TCA cycle, EMP pathway, pentose phosphate pathway, glyoxylic acid cycle, and other central metabolic pathways. Furthermore, the inulinase activity associated with β-fructofuranosidase and high glucose oxidase activity in this strain have been demonstrated. It was found that this yeast-like fungal strain was located at root of most species of Aureobasidium spp. and at a separate cluster of all the phylogenetic trees. The P6 strain was predicted to contain three NRPS gene clusters, five type-I PKS gene clusters, and one type-I NRPS/PKS gene cluster via analysis at the antiSMASH Website. It may synthesize epichloenin A, fusaric acid, elsinochromes, and fusaridione A. Conclusions Based on its unique DNA sequence, taxonomic position in the phylogenetic tree and evolutional position, the yeast-like fungal strain P6 was identified as a novel species Aureobasidium hainanensis sp. nov. P6 isolate and had highly potential applications.
