Isolation of New Aureobasidium Strains That Produce High-Molecular-Weight Pullulan with Reduced Pigmentation

CONTROL OF MOLECULAR WEIGHT DISTRIBUTION OF THE BIOPOLYMER PULLULAN PRODUCED BY THE FUNGUS Aureobasidium pullulans

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...

Development of yeast strains that produce high levels of CoQ10

Coenzyme Q (CoQ, ubiquinone) is a component of the electron transport system in the mitochondria of eukaryotes and is essential for energy production. CoQ consists of a quinone moiety and an isoprenoid chain. Almost all living cells produce CoQ with different isoprenoid chain lengths. For example, CoQ10, which is a popular food supplement, possesses 10 isoprene units. CoQ10 is commercially prod...

Isolation of high molecular weight activators of human plasma prekallikrein.

Two previously undescribed activators of prekallikrein have been purified from human plasma by alcohol frac tionation, ion exchange chromatography, gel filtration, and polyacrylamide gel electrophoresis. Both were apparently homogeneous as judged by electrophoretic mobility and molecular weight. A monomer-dimer relationship between these two activators is suggested by the use of disc gel electr...
