High pressure hydrothermal conversion of Spirulina was studied with iron as catalyst (Matsui et al., 1997). It showed that the bio-oil yield increased linearly from 54.4 to 63.7 wt. % with increasing amount of Fe(CO)5-S from 0 to 1 mmol. The conversion and gas yield were nearly constant. In a similar study, brown macroalga Laminaria saccharina was hydrothermally liquefied to bio-crude in a batch reactor (Anastasakis and Ross, 2011). A maximum bio-crude yield of 19.3 wt. % was obtained with a biomass to water ratio of 1 10 at 350°C and 15 min of residence time. The solid residue contained large proportion of calcium and magnesium, whereas the liquid phase was rich in sugars, ammonium, potassium and sodium.

The detoxifying effect of different seaweeds in a Wistar rat model indicates that the presence of sulfated polysaccharides is crucial in the liver protecting effect of macroalgae (Costa et ah, 2010). Other studies have evidenced the protective effect of seaweeds against liver toxicity induced by galactosamine in a rat model, concluding that this protecting effect is partly mediated by fucoidan, a sulfated polysaccharide from the brown seaweed Laminaria (Kawano et ah, 2007).
