4. Discussion
Researchers have analyzed bioethanol production by microorganisms
of terrestrial or marine origin (Sun and Cheng, 2002;
Lin Tanaka, 2006; Kathiresan and Saravanakumar, 2011;
Senthilraja et al., 2011). However, the marine and terrestrial
strains have not been compared experimentally, but only theoretically
for their bioethanol production (Senthilraja et al.,
2011). The present work perhaps for the first time compared
experimentally the marine and terrestrial strains of S. cerevisiae
on the bioethanol production. The present experiment
proved that both strains of S. cerevisiae produced the bioethanol
but the marine strain produced 17.31% higher bioethanol
than the terrestrial strain, indicating the efficiency of marine
yeast over terrestrial strain. This is in accordance with Kathiresan
and Saravanakumar (2011) who theoretically compared
terrestrial and marine yeasts.
