Abstract
In this study, the productivity of bio-ethanol obtained from various brown-algae raw materials was examined. Brown-algae polysaccharide, consisting of alginate and laminaran, is usable for the effective production of bio-ethanol if it is hydrolyzed to monomer unit. The objective of this study is the production of bio-ethanol from brown-algae using a heat-treatment and acid-treatment. Bio-ethanol was produced by Saccharomyces cerevisiae KCCM1129 and Pachysolen tannophilus KCTC 7937 strains. Laminaran japonica was higher than Sagassum fulvellum and Hizikia fusiformis, Laminaran japonica optimum pre-treatment is used to derive the ethanol production of Saccharomyces cerevisiae KCCM1129 and Pachysolen tannophilus KCTC 7937 respectively 9.16 g/L, 9.80 g/L. The maximum output of Sargassum fulvellum and Hizikia fusiformis was very low as 0.22 g/L.
