PENAMBAHAN TWEEN80TM DAN ERGOSTEROL UNTUK MENGATASI OSMOTIC SHOCK DAN KERUSAKAN MEMBRAN SEL DALAM PROSES FEREMENTASI BIOETANOL DARI NIRA NIPAH KENTAL
Abstract: This study was
conducted to determine the optimization of bioethanol production by
fermentation techniques VHGF with free cell system to see the effect of
combined treatment of unsaturated lipid concentrations (0.2% Tween80. And
Ergoterol) the increase in bioethanol. This research was carried out
experiments with four treatments and measurements in duplicate. The combination
of ergosterol levels namely E0 (0 mg / l), E1 (18 mg / l), E2 (24 mg / l) and
E3 (30 mg / l). Observations were made every 24 hours; include sugar, ethanol,
cell number, and pH. Data were analyzed descriptively by using a tabular or
graphical. The best treatment is a combination of E1 (0.2% Tween80 and
ergosterol 18 mg / l), which produces the largest ethanol 17.57%.
