Biorefinery of the green seaweed Ulva lactuca to produce animal feed, chemicals and biofuels.

ABSTRACT: The growing world population demands an increase in animal protein production. Seaweed may be a valuable source of protein for animal feed. However, a biorefinery approach aimed at cascading valorisation of both protein and non-protein seaweed constituents is required to realise an economically feasible value chain. In this study, such a biorefinery approach is presented for the green seaweed Ulva lactuca containing 225 g protein (N × 4.6) kg^-1 dry matter (DM). The sugars in the biomass were solubilised by hot water treatment followed by enzymatic hydrolysis and centrifugation resulting in a sugar-rich hydrolysate (38.8 g L^-1 sugars) containing glucose, rhamnose and xylose, and a protein-enriched (343 g kg^-1 in DM) extracted fraction.
