Purification and biochemical characterization of polygalacturonases produced by Aureobasidium pullulans.
The extracellular polygalacturonases produced by Aureobasidium pullulans isolated from waters of the Danube river were partially purified and characterized. The pH optima of polygalacturonases produced in the first phases of cultivation (48 h) and after 10 d as well as their optima of temperature, thermal stabilities, molecular masses, isoelectric points, action pattern and ability to cleave po...
متن کاملPartial Purification and Characterization of Fructosyltransferase from Aureobasidium Pullulans
Fructosyltransferase enzymes was isolated and partially purified from Aureobasidium pullulans. The enzyme being intracellular was recovered from the fungal sp. by extraction method using citrate buffer (0.1 M; pH 5.5). Enzyme was Semipurified by salt fractionation method which results increase in specific activity of the enzyme. Study regarding kinetic behavior indicates that the enzyme exhibit...
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 کاملExpanding the feruloyl esterase gene family of Aspergillus niger by characterization of a feruloyl esterase, FaeC.
A feruloyl esterase (FAE) from Aspergillus niger N402, FaeC was heterologously produced in Pichia pastoris X-33 in a yield of 10mg/L. FaeC was most active at pH 7.0 and 50°C, and showed broad substrate specificity and catalyzed the hydrolysis of methyl 3,4-dimethoxycinnamate, ethyl ferulate, methyl ferulate, methyl p-coumarate, ethyl coumarate, methyl sinapate, and methyl caffeate. The enzyme r...
