| Summary: | Ethanol production from pure sugar cane syrup (SCS) were carried out to compare the efficiency of
batch fermentation with commercial glucose using Saccharomyces cerevisiae baker’s yeast and
Saccharomyces cerevisiae CSI-1 (JCM 15097). Fermentation of Baker’s yeast and CSI-1 in SCS
medium supplemented with 0.5% (w/v) of yeast extract at 37oC, initial pH adjusted to 5.5, agitation
200 rpm, produced high concentration of ethanol in 1.5L lab scale fermentor. Ethanol production
by dry Bakers’s reached 138g/L and yield 156.9% of theoretical yield. For CSI-1, a maximal
concentration of 73.3g/L and a yield of 88.9% of theoretical yield were obtained from fresh SCS.
The result from this research demonstrate that in Malaysia, sugar cane syrup could be employed as
an alternative renewable carbon source for ethanol production using batch fermentation with
Saccaharomyces cerivisiae. |
