Electrospun biocomposite nanofibers of ulvan/PCL and ulvan/PEO

open access: yesJournal 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 ...

Sustainable biorefining and bioprocessing of green seaweed (Ulva spp.) for the production of edible (ulvan) and non-edible (polyhydroxyalkanoate) biopolymeric films

open access: yesMicrobial Cell Factories, 2023
A sustainable biorefining and bioprocessing strategy was developed to produce edible-ulvan films and non-edible polyhydroxybutyrate films. The preparation of edible-ulvan films by crosslinking and plasticisation of ulvan with citric acid and xylitol was ...

The study on antioxidant activity of ulvan-calcium derivative [PDF]

open access: yesJournal of Medicinal Plants Research, 2021
Ulvan is a water-soluble polysaccharide that is extracted from the algae Ulva pertusa (Chlorophyta). In this study, ulvan-calcium derivative (U-calcium) was prepared and calcium content was 5.2%. Ulvan-calcium could effectively scavenge on 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis (3-ethyl-benzothiazolie-6-sulfonic acid) (ABTS), hydroxyl ...

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

open access: yesBioscience, 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.

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

open access: yesScientific 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
