Aims: To isolate a reduced pigmentation mutant of Aureobasidium pullulans NYS‐1 and characterize its cellular pigmentation plus its polysaccharide and biomass production relative to carbon source. 
Production of pure β-glucan by Aureobasidium pullulans after pullulan synthetase gene disruption
TLDR
A mutant strain was constructed, A. pullulans NP1221, which produced a pure β-glucan exopolysaccharide, which was white, whereas the wild-type strain produced a black dye and when compared fermentation kinetics between wide-type and mutant strains, the mutant NP 1221 did not produce pullulan.
Exopolysaccharide (pullulan) production from cassava starch residue by Aureobasidium pullulans strain MTTC 1991
Exopolysaccharide (EPS), pullulan, production by Aureobasidium pullulans strain MTCC 1991 was evaluated using cassava starch residue (CSR), wheat bran (WB) and rice bran (RB) as solid substrates as
Aureobasidium pullulans, an economically important polymorphic yeast with special reference to pullulan
Aureobasidium pullulans, popularly known as black yeast, is one of the most widespread saprophyte fungus associated with wide range of terrestrial and aquatic habitats, in temperate and tropical
Aureobasidium pullulans , an economically important polymorphic yeast with special reference to pullulan
TLDR
This review article has emphasized on the orientation, morphology, biochemical characteristics, habitats and its economic potentials of Aureobasidium pullulans with special reference to pullulan.
Production of pigment-free pullulan by swollen cell in Aureobasidium pullulans NG which cell differentiation was affected by pH and nutrition
TLDR
Controlling pH of fermentation is an effective and convenient method to harvest SC for melanin-free pullulan production.
Pullulan: biosynthesis, production, and applications
TLDR
An overview ofpullulan’s chemistry, biosynthesis, applications, state-of-the-art advances in the enhancement of pullulan production through the investigations of enzyme regulations, molecular properties, cultivation parameters, and bioreactor design is presented.

Aureobasidium pullulans-An Industrially Important Pullulan Producing Black Yeast
TLDR
This data indicates that based on the results obtained in this study, the phytochemical properties of the fruit extract of lemon juice and its application as a raw material for biodiesel may have changed over time from fruit extract to vegetable oil and fruit juice.
Strains of Aureobasidium pullulans can lower ochratoxin A contamination in wine grapes.
TLDR
Assessment of one strain carried out in the vineyard during the growing season of 2006 showed that the tested strain was an effective biocontrol agent, reducing both severity of Aspergillus rots and OTA accumulation in wine grapes.

Short Communication: Effect of manganese on polysaccharide production and cellular pigmentation in the fungus Aureobasidium pullulans
Manganese supplementation resulted in higher polysaccharide levels and reduced cellular pigmentation by more than 8- or 17-fold after growth for 7d of the fungus Aureobasidium pullulans ATCC 42023 on
Polysaccharide production by a reduced pigmentation mutant of the fungus Aureobasidium pullulans
TLDR
A reduced pigmentation mutant was isolated from Aureobasidium pullulans ATCC 42023 by chemical mutagenesis and was subsequently characterized and it was noted that the pullulan content of the polysaccharide produced by the parent or mutant strain was lower for sucrose- grown cells than for glucose-grown cells.

Elevated polysaccharide production by mutants of the fungus Aureobasidium pullulans
TLDR
The dry weights of the mutant cells were found not to differ greatly from those of the parent cells whether corn syrup or sucrose served as the carbon source, and the pullulan content of the polysaccharide elaborated by the parent was higher than either mutant.
