Effect of temperature and agitation on the enzymatic synthesis of oligosaccharides and dextran in orange juice

Food Chemistry Advances, 2023
The production of prebiotic fruit juices has been extensively investigated, mainly by the enzymatic route. However, studies involving agitated reactors and other important parameters are lacking.

Transglycosylation of gallic acid by using Leuconostoc glucansucrase and its characterization as a functional cosmetic agent

AMB Express, 2017
Gallic acid glycoside was enzymatically synthesized by using dextransucrase and sucrose from gallic acid. After purification by butanol partitioning and preparative HPLC, gallic acid glucoside was detected at m/z 355 (C13, H16, O10, Na)+ by matrix ...

Immobilization of Glycoside Hydrolase Families GH1, GH13, and GH70: State of the Art and Perspectives

Molecules, 2016
Glycoside hydrolases (GH) are enzymes capable to hydrolyze the glycosidic bond between two carbohydrates or even between a carbohydrate and a non-carbohydrate moiety.

Multiple Techno-Functional Characteristics of Leuconostoc and Their Potential in Sourdough Fermentations

Microorganisms, 2021
In this study, the potential of Leuconostoc as non-conventional sourdough starter cultures was investigated. A screening for antifungal activities of 99 lactic acid bacteria (LAB) strains revealed high suppression of bakery-relevant moulds in nine ...

Physicochemical property and in vivo prebiotic function of α‐(1 → 2) and α‐(1 → 3)‐branched dextran derived from Leuconostoc citreum KD3

JSFA reports, Volume 6, Issue 2, Page 39-49, February 2026.
Abstract Background We isolated lactic acid bacteria (LAB) from Japanese traditional fermented foods and vegetables, and screened for exopolysaccharide (EPS)‐producing strains. The Leuconostoc citreum KD3 was isolated as a strain that produces an α‐glucan (KD3‐dextran) with α‐(1 → 6)‐linked main chain with a considerable amount of α‐(1 → 2) branches ...

Expanding the Enzymatic Polymerization Landscape by Lipid Mesophase Soft Nanoconfinement

Angewandte Chemie, Volume 136, Issue 1, January 2, 2024.
The enzymatic synthesis of dextran in lipidic mesophase catalyzed by the enzyme dextransucrase DSR‐M not only yields polymers at 30 °C that are six times longer than in bulk solution at identical concentrations of reactants, but also allows the reaction to be carried out in subzero liquid water at temperatures as low as −20 °C.

Sucrose-Induced Proteomic Response and Carbohydrate Utilization of Lactobacillus sakei TMW 1.411 During Dextran Formation

Frontiers in Microbiology, 2018
Lactobacillus (L.) sakei belongs to the dominating lactic acid bacteria in indigenous meat fermentations, while diverse strains of this species have also been isolated from plant fermentations. We could recently show, that L.

Proteomic and in silico analyses of dextran synthesis influence on Leuconostoc lactis AV1n adaptation to temperature change

Frontiers in Microbiology, 2023
Leuconostoc lactis is found in vegetables, fruits, and meat and is used by the food industry in the preparation of dairy products, wines, and sugars. We have previously demonstrated that the dextransucrase of Lc.
