Biochemical characterization of a novel ulvan lyase from Pseudoalteromonas sp. strain PLSV. [PDF]

RSC Adv, 2018
Ulvans, complex polysaccharides found in the ulvales (green seaweed) cell wall, contain predominantly 3-sulfated rhamnose (Rha3S) linked to either d-glucuronic acid, l-iduronic acid or d-xylose.

Ulvan lyase assisted structural characterization of ulvan from Ulva pertusa and its antiviral activity against vesicular stomatitis virus

International Journal of Biological Macromolecules, 2020
Marine green algae are valuable sources of diverse health-promoting bioactive components. Ulvan is suitable for biological applications due to its unique structure and numerous bioactivities. Here, the complex structure of ulvan from Ulva pertusa was analyzed using specific ulvan lyase degradation, MS, and NMR detection.

Extract from the Macroalgae Ulva rigida Induces Table Grapes Resistance to Botrytis cinerea [PDF]

Foods, 2022
Fungal pathogens are a central cause of the high wastage rates of harvested fruit and vegetables. Seaweeds from the genus Ulva are fast-growing edible green macroalgae whose species can be found on the shore of every continent, and therefore present a ...

Genes for degradation and utilization of uronic acid-containing polysaccharides of a marine bacterium Catenovulum sp. CCB-QB4 [PDF]

PeerJ, 2021
Background Oligosaccharides from polysaccharides containing uronic acids are known to have many useful bioactivities. Thus, polysaccharide lyases (PLs) and glycoside hydrolases (GHs) involved in producing the oligosaccharides have attracted interest in ...

Marine Polysaccharides: Occurrence, Enzymatic Degradation and Utilization. [PDF]

Chembiochem, 2021
Algae biomass is a source for many valuable compounds for the pharmaceutical and chemical industry. Especially marine polysaccharides contain rare sugars of interest, but a major bottleneck is access to these sugars. In this mini‐review the common knowledge of marine CAZyme‐based deconstruction of these polysaccharides and the biotechnological ...

Glycomolecules: from "sweet immunity" to "sweet biostimulation"? [PDF]

Physiol Plant
Abstract Climate changes and environmental contaminants are daunting challenges that require an urgent change from current agricultural practices to sustainable agriculture. Biostimulants are natural solutions that adhere to the principles of organic farming and are believed to have low impacts on the environment and human health.

A new carbohydrate-active oligosaccharide dehydratase is involved in the degradation of ulvan. [PDF]

J Biol Chem, 2021
Marine algae catalyze half of all global photosynthetic production of carbohydrates. Owing to their fast growth rates, Ulva spp. rapidly produce substantial amounts of carbohydrate-rich biomass and represent an emerging renewable energy and carbon ...

Sulfation of Arabinogalactan Proteins Confers Privileged Nutrient Status to Bacteroides plebeius [PDF]

, 2021
The human gut microbiota (HGM) contributes to the physiology and health of its host. The health benefits provided by dietary manipulation of the HGM require knowledge of how glycans, the major nutrients available to this ecosystem, are metabolized ...
