Comparison Sugar before fermentation and after fermentation Acacia seeds result before fermentation, the sugar content greater than after fermentation. In conclusion after fermentation Acacia seeds yeast to change sugar the possibility the input to a material to produce reducing sugars and use a substrate. Ethanol production in the future.Ethanol from fermentation of 2%. The sugar begins at approximately 45 grams per liter. 3-day sugar fermentation is reduced to 8 grams per liter. The sugar is reduced to switch from sugar to ethanol. Optimization of ethanol can be distilled by removing water out.
