Two mutants of the fungus Aureobasidium pullulans ATCC 42023 were isolated that exhibited elevated polysaccharide production. Both mutants were isolated using a combination of chemical mutagenesis and resistance to growth inhibitors. It was found that both mutants elaborated higher polysaccharide levels after 7 days of growth on corn syrup or sucrose, respectively, compared to ATCC 42023. The dry weights of the mutant cells were found not to differ greatly from those of the parent cells whether… 

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

TLDR
Unlike what has been observed for other biomass substrates, a polysaccharide with a high pullulan content can be produced at a relatively high yield by a fungus grown on a grass hydrolysate indicating thatpullulan could be produced using a biomass-based process.

Polysaccharide production by sponge‐immobilized cells of the fungus Aureobasidium pullulans

TLDR
It was found that fungal cells grown on corn syrup, sucrose or glucose as a carbon source could be immobilized in sponge cubes and that comparable cell weights and viable cell concentrations were immobilized.

Polysaccharide production by immobilized Aureobasidium pullulans cells in batch bioreactors.

Cells of the fungus Aureobasidium pullulans ATCC 201253 were entrapped within 4% agar cubes or 5% calcium alginate beads and were examined for their production of the polysaccharide pullulan in batch

Exopolysaccharide production by entrapped cells of the fungus Aureobasidium pullulans ATCC 201253

TLDR
The production of the exopolysaccharide pullulan using entrapped cells of the fungus Aureobasidium pullulans ATCC 201253 was investigated and fungal cells entrapping in carrageenan demonstrated a lower degree of leakage than did thoseEntrapped in agarose.

A pullulan‐degrading enzyme activity of Aureobasidium pullulans

A pullulan‐degrading enzyme activity was detected in the culture medium after growth of the fungus Aureobasidium pullulans on corn syrup as a carbon source. The product of pullulan catabolism by this

Production of the Polysaccharide Pullulan by Aureobasidium pullulans Cell Immobilization

TLDR
Carrier-binding techniques may be more effective than entrapment techniques for A. pullulans cell immobilization, since carrier-binding is less likely to affect the pullulan content of the polysaccharide being synthesized.
