The result shows that the palm juice is a good feedstock for fermented bioethanol. The best yield is obtained by fermentation of
feedstock containing 25% starter, 0.4% NPK solution, and 5% bread yeast and bio ethanol concentration is about 12% (89%
bioethanol content of feedstock). By using of Saccharomyces serevisiae was obtained ferment liquor with alcohol rate from 12% -
14% and purity about 35 – 42 %.
