BACKGROUND: Plant lignocellulosic biomass can be a source of fermentable sugars for the production of second generation biofuels and biochemicals. The recalcitrance of this plant material is one of the major obstacles in its conversion into sugars. Biomass is...

Anti-Inflammatory Mechanisms of Fucoidans to Treat Inflammatory Diseases: A Review.

Marine drugs
