Enhanced production of Ca2+-polymalate (PMA) with high molecular mass by Aureobasidium pullulans var. pullulans MCW
BACKGROUND Polymalic acid (PMA) has many applications in food and medical industries. However, so far it has not been commercially produced by fermentation. Therefore, it is very important how to develop an economical process for a large scale production of PMA by one step fermentation. RESULTS After over 200 strains of Aureobasidium spp. isolated from the mangrove systems in the South of Chi...
متن کاملOpportunistic infection of the spleen caused by Aureobasidium pullulans.
The mold Aureobasidium pullulans was isolated on several nutrient media from a splenic abscess in a patient with disseminated lymphoma. Examination of stained smears and paraffin sections revealed fungal structures characteristic of this organism. This is the first reported association of A. pullulans with an opportunistic visceral infection.
متن کاملBiosynthesis of novel exopolymers by Aureobasidium pullulans.
Aureobasidium pullulans ATCC 42023 was cultured under aerobic conditions with glucose, mannose, and glucose analogs as energy sources. The exopolymer extracts produced under these conditions were composed of glucose and mannose. The molar ratio of glucose to mannose in the exopolymer extract and the molecular weight of the exopolymer varied depending on the energy source and culture time. The g...
متن کاملPullulan 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 کاملAntibacterial Activity of Aureobasidium Pullulans
Aureobasidium pullulans is ubiquitous, polymorphic and black fungus producing a variety of important metabolites including enzymes, polysaccharides and single cell protein. It is considered as a probable source for antagonistic activity against a number of phytopathogenic fungi and possible biocontrol agent of post harvest diseases. The present work aims at the antibacterial compounds produced ...
