The result of my work in one semester

PRODUCTION OF BIOETHANOL FROM SORGHUM IN SIMULTANEOUSLY SACCHARIFICATION AND FERMENTATION USING YEAST Saccharomyces cerevisiae

Enzymatic hydrolisis of starch to result glucoses is a better methode than chemical hydrolisis, but it need more time that add many mre time also for bioethanol production. Therefore, need to shorten time needed and of the ways is Simultaneously Saccaharification and Fermentation(SSF) methode.

This research had been done in laboratorium scale. Bioethanol production began with the material preparation and be continued with liquifaction use α-amylase.

           Based on the result, the optimum conditon for the SSF process is 33^oC in temperature and glucoamylase 156 unit/gram for 48 hours. This resulted the ethanol content of 9,38%(v/v), productivity 0,15 [gram ethanol].[mL solution.jam]^-1  , conversion of glucose to ethanol 30% and yield 29,7% gr etanol/gr sorghum flour .
