Revised domain structure of ulvan lyase and characterization of the first ulvan binding domain [PDF]

Scientific Reports, 2017
AbstractBiomass waste products from green algae have recently been given new life, as these polysaccharides have potential applications in industry, agriculture, and medicine. One such polysaccharide group called ulvans displays many different, potentially useful properties that arise from their structural versatility.

Electrospun biocomposite nanofibers of ulvan/PCL and ulvan/PEO

Journal of Applied Polymer Science, 2015
ABSTRACTNovel fibrous biocomposites comprising ulvan, a sulfated polysaccharide extracted from the green seaweed Ulva rigida, and either polycaprolactone or polyethylene oxide were successfully prepared using the electrospinning technique. The morphology and the chemical composition of the nanofibers were characterized using SEM and FT‐IR analyses ...

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome. [PDF]

FEBS J
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

A novel ulvan lyase family with broad-spectrum activity from the ulvan utilisation loci of Formosa agariphila KMM 3901 [PDF]

Scientific Reports, 2018
AbstractUlvan, which is one of the major structural polysaccharides of the cell walls of green macroalgae, is degraded by ulvan lyases via the β-elimination mechanism with the release of oligosaccharides that have unsaturated 4-deoxy-L-threo-hex-4-enopyranosiduronic acid (∆) at the non-reducing end. These ulvan lyases belong to the PL24 or PL25 or PL28

Characterization of an Alteromonas long-type ulvan lyase involved in the degradation of ulvan extracted from Ulva ohnoi [PDF]

Bioscience, Biotechnology, and Biochemistry, 2017
Abstract Ulvan is a sulfated polysaccharide found in the cell wall of the green algae Ulva. We first isolated several ulvan-utilizing Alteromonas sp. from the feces of small marine animals. The strain with the highest ulvan-degrading activity, KUL17, was analyzed further.

Metabolic engineering enables Bacillus licheniformis to grow on the marine polysaccharide ulvan [PDF]

Microbial Cell Factories, 2022
Background Marine algae are responsible for half of the global primary production, converting carbon dioxide into organic compounds like carbohydrates. Particularly in eutrophic waters, they can grow into massive algal blooms.

Production of Ulvan Oligosaccharides with Antioxidant and Angiotensin-Converting Enzyme-Inhibitory Activities by Microbial Enzymatic Hydrolysis

Fermentation, 2021
Seaweed oligosaccharides have attracted attention in food, agricultural, and medical applications recently. Compared to red and brown seaweeds, fewer studies have focused on the biological activity of green seaweed’s oligosaccharides. This study aimed to
