Effect of pH and the initial concentration of yeast extract on regulation of dimorphism and exopolysaccharide formation of Aureobasidium pullulans in batch culture
TLDR
The effect of yeast extract on morphology and exopolysaccharide formation of Aureobasidium pullulans was followed quantitatively in batch cultivations in 2 1 fermenters and formation of yeast-like cells was a prerequisite of formation of exopoly Saccharide.About:

Evaluation of carob pod as a substrate for pullulan production by Aureobasidium pullulans
TL;DR: In this article, the production of extracellular polysaccharides from carob pod extract by Aureobasidium pullulans in batch fermentation was investigated, and the highest values of pullulan proportion and fermentation efficiency were assumed at initial sugar concentration of 25 g/L, pH 6.5 and 30°C.

Effect of pH on the batch fermentation of pullulan from sucrose medium.
TL;DR: The bistaged pH process for the production of pullulan enhanced the polysaccharide concentration in the medium, influenced the rheological properties of the fermentation broth, and has a potential of operation under nonsterile and nonaseptic conditions.

A vegetative cycle of Pullularia pullulans
S. Ramos,I. Garcia Acha +1 more
TL;DR: From a study of the interrelationships of different forms of Pullularia pullulans a cycle of vegetative growth is proposed and the nitrogen source of the culture medium seems to be particularly important in controlling the vegetative cycle.

Role of pH and nitrogen limitation in the elaboration of the extracellular polysaccharide pullulan by Pullularia pullulans.
TL;DR: The conditions generated in the culture medium which activate the secretion of polysaccharide have been sought for, and, in particular, the roles of extracellular pH and nitrogen limitatation are examined.
