Bio-ethanol as an energy source for transportation alternative fossil fuels has been interest. As a result, production of bio-ethanol using seaweed has been investigating. In this study, we were investigated ethanol fermentation by enzymatic hydrolysis of Laminaria japonica and alginate from L. japonica. Ethanol fermentation was used by Erwinia tasmaniensis reported to secrete alginate lyase. Production of ethanol at anaerobic condition was showed better results than aerobic condition. Produced ethanol according to the amount of substrate was no significant difference on the alginate medium at aerobic condition. But at anaerobic condition, ethanol was found to be 0.16 g/L and 0.19 g/L at the substrate of 5 g/L and 10 g/L, respectively. L. japonica media at aerobic and anaerobic condition was produced maximum 0.192 g/L and 0.327 g/L ethanol, respectively. |
