Abstract

Objective: The purpose of this research was to investigate the potential of yeast-producing bioethanol from few type of grapes and durians.
Methods: The isolation of potential yeast was carried out from five different types of fruits, namely, red grape, black grape, durian Medan, durian
Bangkok, and durian Monthong. Optimum fermentation condition was obtained by comparing shaking and non-shaking, detoxifying the hydrolysate,
varying temperature, and concentration of N source in the culture medium.
Results: The results of an analysis using gas chromatography showed that the ideal conditions for the fermentation of bioethanol were at a temperature
below room temperature (+220°C), without shaking, using the hydrolysate, without detoxification, and with a 1% concentration of ammonium acetate
as a source of N. Among the isolates, isolate DM1 obtained from durian Medan showed a strong potential to produce bioethanol but at lower levels
than Saccharomyces cerevisiae. The concentration of ethanol produced was 0.241%.
Conclusion: A yeast isolate with a strong potential to produce bioethanol was discovered as the DM1, which isolated from Medanese durian. The
isolate produced 0.241% bioethanol. However, fermentation optimization efforts using an oil palm empty fruit bunch hydrolysate substrate did not
yield higher concentrations.

Keywords: Bioethanol, Biomass, Ethanol, Fermentation, Hydrolysate, Isolation, Saccharomyces cerevisiae, Oil palm empty fruit bunch.
