Abstract
Green alga, Ulva pertusa kjelmann has been known to be one of the largest pollutants in Korea. Therefore, the efficient pretreatment processes have been required to improve the yields of fermentable sugar. The optimal pretreatment conditions were determined to be 195℃ for 15 min. The sugar yield of glucose and xylose were estimated as 20.5%, and 5.0% respectively, based on theoretical yields. However solid residues were estimated enzymatic digestibility of 90-95% with cellulase loading of 15 FPU/g glucan. This process was proved to generate the low concentration of Hydroxy-Methyl-Furfural (51 ppm), which resulted in ethanol production with 95% of the maximum conversion yield from glucose in the culture of Saccharomyces cerevisiae (ATCC, 24858). This study showed that Ulva pertusa kjellmann can be used as a bioetahnol resource using the high temperature liquefaction process.
