Optimization of The Bioconversion of Spirogyra Hyalina Hydrolysates to Become Ethanol Using Zymomonas Mobilis
This study aims to determine the effect of different types of gases, initial pH, and the fermentation duration to cell biomass, pH, reducing sugar concentration, and ethanol concentration that was produced from fermentation of the Spirogyra hyalina hydrolysates to become ethanol using Zymomonas mo...

| Summary: | This study aims to determine the effect of different types of gases, initial pH, and the fermentation duration to
cell biomass, pH, reducing sugar concentration, and ethanol concentration that was produced from fermentation
of the Spirogyra hyalina hydrolysates to become ethanol using Zymomonas mobilis. Fermentation performed
under anaerobic conditions with the variations of nitrogen gas and hydrogen gas in the space fermenter. The
results showed that different types of gases, pH, and the fermentation duration give an effect on the cell
biomass, pH, reducing sugar concentration, and ethanol concentration that was produced from fermentation of
Spirogyra hyalina hydrolysates using Zymomonas mobilis. The highest levels of ethanol and biomass achieved
by Zymomonas mobilis in the presence of hydrogen gas. It means that the hydrogen gas that was injected into
the fermenter space can act as a reducing agent for the formation of NADH. NADH in the cell metabolism of
Zymomonas mobilis functioning for the formation of ethanol. |
