“…The highest pullulan production (162.3 g l −1 ), however, has been achieved with glucose as a carbon source (Li et al 2023 ). Pullulan is a white, water-soluble, tasteless, and odorless biological binder mainly used as a food additive, functioning as a thickener, stabilizer, filler, gelling agent, and/or adhesive (Muthusamy et al 2022 ; Prajapati et al 2013 ). For example, it is used as a substitute for gelatin, starch, or wheat flour.…”

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

“…For example, Aureobasidium species are resistant to Botrytis cinerea and Rhizopus stolonifera as biological control agents, and they can also be used as sources of single-cell proteins [21,22]. Aureobasidium pullulans is often fermented to produce β-polymalic acid, laccase, liamocins, pullulan polysaccharides, and other commercial compounds [14,[23][24][25][26][27][28]. Liamocins display pharmacological activities including anti-Streptococcus and anticancer [29].…”

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.

“…They reported that the nanofibrous Pull membrane presented a smaller pore size providing an efficient barrier against bacterial transmission and enabling optimum oxygen and water vapor transmission. Other important works were published by Raychaudhuri et al 23 and Muthusamy et al 24 which both proposed a review approaching the several applications of pullulan in the biomedical area. They reported the development of pullulan‐based formulations with excellent biocompatibility and antimicrobial properties for cancer treatment and tumor targeting, stem cell therapy, vaccine, and gene deliveries.…”

This study aimed to evaluate the effect of pullulan (Pull) on a renewable polyurethane sponge‐like scaffold synthesized from the Pull mixture with the castor oil‐based polyol and the prepolymer using the situ foaming method. The Pull contents on the sponge‐like are 5, 10, and 20 wt.%. The samples were evaluated by optical microscopy (OM), scanning electron microscopy (SEM), density, Fourier transform infrared spectroscopy (FTIR), contact angle, Thermogravimetry, X‐ray diffraction analysis (XRD), and compression strength test, respectively. FTIR results indicated that Pull was hydrogen‐bonded to PU foam chains and increased the sponge‐like scaffolds density, inducing a decrease in average cell size compared to the pristine PU, confirming that they act as nucleating agents. The Pull addition improved PU foams' hydrophobicity and mechanical properties and caused a thermal stability median between Pull and pristine PU. Thus, all renewable sponge‐like scaffolds were hydrophobics and presented appropriate mechanical behavior, exhibiting better physicochemical properties, and appearing as promising candidates for biomedical applications.
