The goal of this collaborative project was to explore the feasibility of using macroalgae as a feedstock for biofuel. Specifically to focus on the conversion of macroalgae to biofuels or other valuable co-products which are low carbon, cost-effective, and sustainable. The main objectives were to develop a library of the composition of macroalgae, develop optimal pretreatments, investigate and determine and optimize enzymatic cocktails capable of efficiently hydrolyzing the resultant polysaccharides into monomeric sugars. The initial technical objective was to identify, verify, and develop new modes of pre-treatment and evaluate enzymes for hydrolysis of macroalgae to fermentable sugars.
