No significant differences in fermentative parameters were
observed between COMMERCIAL-yeast and UNICAMP-V1 strain. The UFMG-A1240 strain showed the
lowest ethanol yield and therefore not suitable for the production of distilled spirits made of bananas,
despite being useful for the production of cachaça. Methanol contents did not significantly vary among
the five strains tested, except for UFMG-A1007, which produced significantly higher quantities of 0.19
ml/100 ml anhydrous alcohol. However, higher alcohols contents varied significantly between the five
strains tests, with the UFMG-A1007 and UFMG-A1240 strains producing the lowest quantities of higher
alcohols (30.04 and 48.69 mg/100 ml anhydrous alcohol, respectively). In conclusion, the S. cerevisiae
strains UNICAMP-V1 and the COMMERCIAL-yeast showed better fermentation behavior, did not
produce high methanol and higher alcohols amounts, and therefore were recommended for the
production of distilled spirits made of banana in pilot-scale plants.
