Total reducing sugars (g 100 mL−1, black bars) and ethanol production (g 100 mL−1, grey bars), in fermentations carried out with the industrial S. cerevisiae yeast (PE-2) contaminated with the rough strain of S. cerevisiae (rough) and or L. fermentum (Lf), in sugarcane juice and molasses, at 30 °C, for six 9-h fermentation cycles. Results are the mean of two replicates and error bars correspond to the standard deviations
