Optimum fermentation condition was obtained by comparing shaking and non-shaking, detoxifying the hydrolysate,<br />varying temperature, and concentration of N source in the culture medium.<br /><strong>Results:</strong> The results of an analysis using gas chromatography showed that the ideal conditions for the fermentation of bioethanol were at a temperature<br />below room temperature (+220°C), without shaking, using the hydrolysate, without detoxification, and with a 1% concentration of ammonium acetate<br />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<br />than Saccharomyces cerevisiae. The concentration of ethanol produced was 0.241%.<br /><strong>Conclusion:</strong> A yeast isolate with a strong potential to produce bioethanol was discovered as the DM1, which isolated from Medanese durian. The<br />isolate produced 0.241% bioethanol. However, fermentation optimization efforts using an oil palm empty fruit bunch hydrolysate substrate did not<br />yield higher concentrations.</p> ER -
