Pullulan Elaboration by Aureobasidium pullulans Protoplasts.
Protoplasts of Aureobasidium pullulans are capable of producing pullulan. Biosynthesis of the polymer pullulan required induction with kinetics similar to those of whole cells. The protoplasts also produced a heteropolysaccharide component containing mannose, glucose, and galactose. The relative proportions of the pullulan and heteropolysaccharide fractions were a function of glucose concentrat...

متن کاملRole of pH and nitrogen limitation in the elaboration of the extracellular polysaccharide pullulan by Pullularia pullulans.
During the growth of the yeastlike fungus Pullularia pullulans on glucose as sole carbon source, the cell-mass does not increase concomitantly with the elaboration of the extracellular polysaccharide pullulan, but precedes it. 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 ...
متن کاملPullulan production from Aureobsidium pullulans by continuous culture
Ten isolates of Aureobasidium pullulans were screened for the highest production of pullulan and minimal melanin production from Fayoum Governorate, Egypt. The optimum conditions for continuous culture were studied; temperature was 24°C, while pH 5.0, and agitation speed was at 500 rpm, while the aeration rate was 2.5 vvm and the best flow rate was 1 L/ 24 h. The maximum production of pullulan ...
متن کاملAdhesion of Aureobasidium pullulans is controlled by uronic acid based polymers and pullulan.
Aureobasidium pullulans is a potentially pathogenic microfungus that produces and secretes the polysaccharide pullulan and other biomacromolecules, depending on the microbe's physiological state. The role of these macromolecules in mediating adhesion and attachment were examined. Interfacial forces and adhesion affinities of A. pullulans were probed for early-exponential phase (EEP) and late-ex...
