Enzymatic Synthesis and Identification of Two Trisaccharides Produced from Lactulose by Transgalactosylation

open access: yesJournal of Agricultural and Food Chemistry, 2007
The enzymatic transgalactosylation during lactulose hydrolysis was studied using the beta-galactosidase from Kluyveromyces lactis and an initial lactulose concentration of 250 g/L. During hydrolysis of lactulose, the formation of two novel trisaccharides was followed by high-performance anion-exchange chromatography with pulsed amperometric detection ...

Sugar‐sensing swodkoreceptors and swodkocrine signaling

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 5, Page 944-961, May 2025.
Sugar‐sensing swodkoreceptors that trigger swodkocrine signaling. Abstract Sugars are one of the major metabolites and are essential for nucleic acid synthesis and energy production. In addition, sugars can act as signaling molecules. To study sugar signaling at the systemic level, there is an urgent need to systematically identify sugar‐sensing ...

Heterologous expression of a recombinant lactobacillal -galactosidase in Lactobacillus plantarum: effect of different parameters on the sakacin P-based expression system [PDF]

open access: yes, 2015
Background: Two overlapping genes lacL and lacM (lacLM) encoding for heterodimeric -galactosidase from Lactobacillus reuteri were previously cloned and over-expressed in the food-grade host strain Lactobacillus plantarum WCFS1, using the inducible ...

Oligosaccharide production using β-galactosidase from Lactobacillus bulgaricus and Kluyveromyces lactis in sweetened reconstituted nonfat dry milk

open access: yesJournal of Dairy Science
: β-Galactosidase (B-gal) is a vital enzyme used in the food industry to reduce lactose from dairy ingredients through hydrolysis and to synthesize galacto-oligosaccharides (GOS), a known bifidogenic prebiotic, from galactose moieties through ...

In vitro and in vivo digestibility of prebiotic galactooligosacharides synthesized by β‐galactosidase from Lactobacillus delbruecki subsp. bulgaricus CRL450

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 11, Page 6769-6777, 30 August 2024.
Abstract BACKGROUND The general assumption that prebiotics reach the colon without any alterations has been challenged. Some in vitro and in vivo studies have demonstrated that ‘non‐digestible’ oligosaccharides are digested to different degrees depending on their structural composition.
