Discussion

Study identifies wild fermentative yeast strains with high ethanol yield in Misiones fruits, suggesting ability to produce regional fruit wines.

Strains P6 and P11 showed the highest ethanol yield at 77% and 69.6%, respectively, after evaluation.
A total of 62 yeast strains were isolated from the spontaneous fermentation of pitanga and black mulberry fruits.
P6 and P11 displayed exceptional tolerance to stress factors, enhancing their potential in ethanol production.
The study emphasizes the potential of native yeasts for producing high-quality regional fruit wines.

Maidana et al. (2025) studied this question.
