Unraveling the molecular mechanism of polysaccharide lyases for efficient alginate degradation. [PDF]

Nat Commun
Alginate lyases (ALs) are essential for breaking down brown macroalgae alginates, widely used naturally-occurring polysaccharides. Their molecular mechanisms remain challenging due to the lack of catalytically competent Michaelis-Menten complex structures.

Alginate Lyases from Alginate-Degrading Vibrio splendidus 12B01 Are Endolytic [PDF]

Applied and Environmental Microbiology, 2015
ABSTRACT Alginate lyases are enzymes that degrade alginate through β-elimination of the glycosidic bond into smaller oligomers. We investigated the alginate lyases from Vibrio splendidus 12B01, a marine bacterioplankton species that can grow on alginate as its sole carbon source.

Method Designed To Detect Alginate-Degrading Bacteria [PDF]

Applied and Environmental Microbiology, 1990
A simple turbidimetric method was developed to detect alginate degradation. Bacteria were grown in alginate-containing media, and culture fluids were mixed with an acidic albumin solution. Failure to develop a white turbidity indicated an alginate degrader. The method showed alginate degradation by Vibrio alginolyticus

The effect of oxidation on the degradation of photocrosslinkable alginate hydrogels [PDF]

Biomaterials, 2012
Recently, we reported on a new photocrosslinkable alginate-based hydrogel, which has controllable physical and cell adhesive properties. The macromer solution containing cells can be injected in a minimally invasive manner into a defect site and crosslinked while maintaining high cell viability.

Alginate Scaffolds for Mesenchymal Stem Cell Cardiac Therapy: Influence of Alginate Composition [PDF]

, 2012
Despite the success of alginate scaffolds and mesenchymal stem cells (MSCs) therapy in cardiac failure treatment, the impact of the physicochemical environment provided by alginate matrices on cell behavior has never been investigated.

Degradation-Kinetics-Controllable and Tissue-Regeneration-Matchable Photocross-linked Alginate Hydrogels for Bone Repair

, 2022
Photocross-linked alginate hydrogels, due to their biodegradability, biocompatibility, strong control for gelling kinetics in space and time, and admirable adaptability for in situ polymerization with a minimally invasive approach in surgical procedures,

Purification and Characterization of Alginate Lyase from Mucoid Pseudomonas aeruginosa Strain 214 [PDF]

Journal of Genetic Resources, 2015
Pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in compromised patients. The ability of Pseudomonas aeruginosa to produce chronic infection is based in part on its ability to biosynthesis of biofilm, and alginate ...

INCREASE OF SHELF LIFE STABILITY AND KINETICS STUDY OF TYPE 1 BROWN RICE MILK THROUGH ADDITION OF ALGINATE EXTRACT FROM Sargassum binderi

Food ScienTech Journal, 2019
Brown rice milk obtained from rice is used for lactose intolerance and as a lower fat milk choice. This research aimed to use the sodium alginate extracted from Sargassum binderi as a stabilizer and degradation of brown rice milk.

Improving The Antioxidant Activity of Sodium Alginate from Sargassum sp. by Thermal Heating and Chemical Methods

Jurnal Kelautan Tropis, 2020
The relationship between molecular structure and bioactivity was evaluated for sodium alginates obtained under different degradation treatment (raw alginates, heat-treated, and chemical-treated) from Sargassum sp. This study was conducted to identify the

Identification of 2-keto-3-deoxy-d-Gluconate Kinase and 2-keto-3-deoxy-d-Phosphogluconate Aldolase in an Alginate-Assimilating Bacterium, Flavobacterium sp. Strain UMI-01

Marine Drugs, 2017
Recently, we identified an alginate-assimilating gene cluster in the genome of Flavobacterium sp. strain UMI-01, a member of Bacteroidetes. Alginate lyase genes and a 4-deoxy-l-erythro-5-hexoseulose uronic acid (DEH) reductase gene in the cluster have ...
