| dc.description.abstract | The use of alternative substrates to produce biofuel is a striking option nowadays. This study aimed to screen bioethanol- producing yeast strains. From different flowers, 65 yeasts were isolated. Twelve isolates assimilated glucose by liberation of CO 2 anaerobically. Out of these, only 5 yeast isolates fermented glucose in medium consisting of 0.8 g/L Mg 2+ions to produce 2.05 ±0.03% ethanol. The selected five strains were identified as members of the generaMetschnikowiaorMeyerozymabased on molecularcharacterization. Selected yeast strains were used for conversion of rice into bioethanol following dilute acid hydrolysis and fermentation.Consistent ethanol production was 1.80 ± 0.05% at days 2 4 byMetschnikowia cibodasensisY34 and 2.20 ± 0.21% byMeyerozymacaribicaY42 at days 4 6 with a gradual decrease at the time of experiment termination (day 10).Metschnikowia cibodasensisY34 andMeyerozyma caribicaY42 produced the highest ethanol at pH 3, i.e. 1.75 ± 0.14% at days 3 and 5 and 2.05 ± 0.14% at days 1 and 3,respectively, upon incubation with different pH levels and 1% NaCl. Growth and ethanol production at pH 4 and 5 was close to that atpH 3, with a slight increase in production byMetschnikowia cibodasensisY34 at pH 4 up to day 3. | |
