Bacterial Fermentation of Sweet Sorghum for Ethanol Production
July 11, 2008| |
Recognizing the potential of sweet sorghum for the bio- ethanol production, a research team at Khon Kaen University, Thailand has reported an attempt to examine the capability of sweet sorghum to produce ethanol using Zymomonas mobilis. This bacterium used sweet sorghum stem juice as a carbon source for fermentation in batch, fed-batch and continuous fermentations. In the initial experiments to identify the best strain from the five strains tested, the strain TISTR 548 was chosen. To further investigate its optimum condition for ethanol production in batch, the optimal agitation rate used was 100 rpm in which maximum yield and productivity of 0.48 to 1.41 g l-1 h-1 could be achieved.
