Deactivation of isoamylase and β-amylase in the agitated reactor under supercritical carbon dioxide.

Bioprocess and biosystems engineering, 33(8), 1007-1015 (2010-04-08)
The current research examines the impact of agitation on deactivation of isoamylase and β-amylase under supercritical carbon dioxide (SC-CO2). Our experimental results showed that the activity of either enzyme decreased with increasing pressure or speed of agitation. The degree of

Three isoamylases of Rhyzopertha dominica (termed RdA70, RdA79, and RdA90 according to their relative mobility in gel electrophoresis) were isolated by ammonium sulfate fractionation and hydrophobic interaction chromatography. RdA70 and RdA79 showed an optimal pH of 7.0, whereas for RdA90

Amylose, a putative linear alpha-(1-->4)-glucan and a component of most starches, was isolated from potato, rice, and wheat starches by forming the 1-butanol complex in a solution of the starches. It previously had been found that these amyloses were incompletely

In this study, we investigated which enzymes are involved in debranching amylopectin during transient starch degradation. Previous studies identified two debranching enzymes, isoamylase 3 (ISA3) and limit dextrinase (LDA), involved in this process. However, plants lacking both enzymes still degrade

Instrumental and procedural optimizations are developed for a new method to obtain 2-dimensional distributions for branched homopolymers based on size and branching. The method uses 2-dimensional off-line size-exclusion chromatography (SEC) and chemical debranching, in this case using debranching enzymes on
