Microstructural and carbohydrate compositional changes induced by enzymatic saccharification of green seaweed from West Africa [PDF]

open access: yes, 2020
The use of marine macroalgae as carbon source for fermentation is gaining increasing attention due to their high carbohydrate content and availability. Three green seaweed species Chaetomorpha linum, Ulva fasciata and Caulerpa taxifolia were investigated

Optimising pretreatment methodologies to improve the use of nuisance macroalgal biomass from bloom Ulva spp. prior to enzyme hydrolysis for downstream processing and application

open access: yesApplied Phycology
The utilization of macroalgae for bioresource applications, particularly those derived from Ulva spp. is gaining global interest. This study presents an optimized process for the separation of Ulva biomass into its reducing sugar constituents, covering ...

Is there lignin in the Ulva cell wall? A multidisciplinary structural investigation to provide new insights into cell wall evolution and macroscopic complexity in the chlorophyte green seaweeds [PDF]

open access: yes, 2023
Seaweeds are not only an integral component of the marine ecosystem via their role in global carbon and sulfur cycles, but also have significant economic value as crops for food and fuel, with certain intertidal seaweeds like the green 'sea lettuce' Ulva

Structural and molecular basis for the substrate positioning mechanism of a new PL7 subfamily alginate lyase from the Arctic [PDF]

open access: yes, 2020
Alginate lyases play important roles in alginate degradation in the ocean. Although a large number of alginate lyases have been characterized, little is yet known about those in extremely cold polar environments, which may have unique mechanisms for ...

Long-type ulvan lyase in Alteromonas sp. is a major enzyme involved in degradation of ulvan extracted from Ulva ohnoi

open access: yes, 2017
Abstract: Ulvan is one of the key sulfated polysaccharide components constituting the cell walls of green algae, Ulva. A little study has been performed so far on the ulvan degrading bacterial enzymes. In order to utilize ulvan effectively by breaking down to oligosaccharides and monosaccharide, we have studied ulvan-degrading bacterial enzymes.

Metabolism of multiple glycosaminoglycans by Bacteroides thetaiotaomicron is orchestrated by a versatile core genetic locus [PDF]

open access: yes, 2020
The human gut microbiota (HGM), which is critical to human health, utilises complex glycans as its major carbon source. Glycosaminoglycans represent an important, high priority, nutrient source for the HGM.

Evaluating Swedish seaweeds for biorefinery [PDF]

open access: yes, 2020
A sustainable future demands a transition from oil to biomass to produce fuels, chemicals, commodities, and energy. However, to generate the predicted amount of bioenergy required by 2050, all the biomass harvested today should be utilized.

The human gut microbe Bacteroides thetaiotaomicron encodes the founding member of a novel glycosaminoglycan-degrading polysaccharide lyase family PL29 [PDF]

open access: yes, 2018
Glycosaminoglycans (GAGs) and GAG-degrading enzymes have wide-ranging applications in the medical and biotechnological industries. The former are also an important nutrient source for select species of the human gut microbiota (HGM), a key player in host–

Ulvan: A systematic review of extraction, composition and function [PDF]

open access: yes, 2019
Species of green macroalgae (Chlorophyta) of the genus Ulva are edible seaweeds with a range of health promoting bioactive components. Ulva is high in dietary fibre which promotes gastrointestinal health and is linked to a reduction in the incidence of ...
