G-specific alginate lyases are important tools for alginate fragment biodegradation and oligosaccharide production, which have great potential in alginate refining research. In this research, a novel G-specific alginate lyase Aly7Ce was cloned, expressed, and characterized, with the optimal reaction conditions at 30 °C and pH 8.0.

Exploratory SAXS and HPAEC-PAD studies of starches from diverse plant genotypes
Carbohydrate Polymers, 2006A substantial amount of effort has been expended on developing a suitable model to describe the small angle X-ray scattering (SAXS) profiles of starch. The modelling work now offers good descriptions of the fine structure of the starch granule, with recent advances [Daniels, D.R., & Donald, A.M. (2003).

Trehalose is a non‐reducing disaccharide involved in stress tolerance in plants. To understand better the role of trehalose in the osmotic stress response in linseed (Linum usitatissimum), trehalose content in leaves was studied. First, the method commonly used for sugar determination, high performance anion exchange chromatography with pulsed ...

Quantitative Analysis of Debranched Amylopectin by HPAEC-PAD with a Postcolumn Enzyme Reactor
Journal of Liquid Chromatography & Related Technologies, 1997Abstract The chain-length distribution of debranched amylopectin was analyzed by using high performance anion-exchange chromatography with an amyloglucosidase (AMG) reactor and a pulsed amperometric detector (HPAEC-ENZ-PAD). The effects of reactor length, reactor temperature, and additional a-amylase reactor were studied. Results showed that a 2 mm i.d.

In vitro methods are widely used to characterise dietary fibre fermentability in the human hind gut. The activity of faecal bacteria can be followed by measuring fermentation products and substrate degradation. This paper describes a method for establishing neutral-sugar profiles by HPAEC-PAD during in vitro fermentation studies.

AbstractMetabolomics is a powerful tool for the study of biological systems. Besides analytical techniques, cell harvest and extraction are critical steps, especially when studying encapsulated streptococci. We have compared four different harvesting techniques for biomass from liquid culture of the hyaluronic acid (HA)‐producing bacterium ...
