摘要：The research objective was to modify bioethanol fermentation by batch condition from seaweed (Eucheuma cottonii) as a substrate to produce a high yield of bioethanol.Type of sugar found in acid hydrolisates Eucheuma cottonii consisted of 4.95% galactose,0.25% glucose,0.04% xyllose,and 0.02% maltoheptaosa.The highest ethanol production from adapted Saccharomyces cerevisiae IPBCCAL IX was 2.38% (v/v) ethanol in fermentation broth,with 79.09% substrate efficiency and 56.30% fermentation efficiency which was fermented for 6 days.The highest ethanol production from adapted Pachysolen tannophilus IPBCC AC IX was 0.11% (v/v) ethanol in fermentation broth,with 15.39% substrate efficiency and 2.60% fermentation efficiency which fermented for 4 days.The highest ethanol production with culture refresh treatment using adapted Pachysolen tannophilus IPBCC AC IX after 24 hours fermentation by adapted Saccharomyces cerevisiae IPBCCAL IX was 0.81% (v/v) ethanol in fermentation broth,with 82.42% substrate efficiency and 19.79% fermentation efficiency which fermented for 6 days.The highest ethanol production with culture refresh treatment using adapted Saccharomyces cerevisiae IPBCCAL IX after 24 hours fermentation by adapted Saccharomyces cerevisiae IPBCCAL IX was 1.76% (v/v) ethanol in fermentation broth,with 53.06% substrate efficiency and 43.53% fermentation efficiency which fermented for 6 days.
