Harnessing Sargassum inundation biomass: Biobased products versus energy valorisation
article
Different routes for extraction of polysaccharides (fucoidan, alginate) and biomethane production were evalu ated for the valorisation of Sargassum spp. biomass. Modest yields of alginate (145 g/kg dry biomass) and fucoidan (43 g/kg dry biomass) were achieved through sequential low temperature acidic aqueous treatment and alkaline extraction. The crude extracts showed low molecular weights (45.2 and 79.5 kDa, respectively) and had brown colour suggesting the presence of polyphenols. High temperature aqueous treatment increased fucoidan extraction efficiency, as indicated by higher fucose content in hydrolysates; however, the extract had low mo lecular weight.
