Brown algae, as the main source of alginate, are a type of marine biomass with a very high
output. Alginate, a polysaccharide composed of β-D-mannuronic acid (M) and α-L-guluronic …

Alginate is a biopolymer used extensively in the food, pharmaceutical, and chemical
industries. Alginate oligosaccharides (AOS) derived from alginate exhibit superior biological …

Alginate lyases catalyze the degradation of alginate, a complex copolymer of α-L-guluronate
and its C5 epimer β-D-mannuronate. The enzymes have been isolated from various kinds of …

Brown macroalgae have attracted great attention as an alternative feedstock for biorefining.
Although direct conversion of ethanol from alginates (major components of brown …

Adaptive radiations are important drivers of niche filling, since they rapidly adapt a single
clade of organisms to ecological opportunities. Although thought to be common for animals …

Highlights•Marine polysaccharide specific glycoside hydrolases often belong to new
families.•Many new structures of enzymes acting on agars, alginate or ulvans are …

Marine macroalgae (green, red and brown macroalgae) have attracted attention as an
alternative source of renewable biomass for producing both fuels and chemicals due to their …

Alginate lyases are essential tools for depolymerizing alginate into bioactive
oligosaccharides and fermentable monosaccharides. Herein, we characterized a novel …

Seaweeds are among the most important biomass feedstocks for the production of third-
generation biofuels. They are also efficient in carbon sequestration during growth and …
