FIGURE 1.

Loss of viability expressed as Log N/N₀ of single cultures UNQLp11, UNQLp155, UNQOe31b, UNQOe73.2, and blend cultures UNQLp11/UNQOe31b, UNQLp11/UNQOe73.2, UNQLp155/UNQOe31b, and UNQLp155/UNQOe73.2 after 14 days of incubation in Malbec wine samples at 21°C. Gray bars indicate plate viable cell count number of strains belonging to Oenococcus species; black bars indicate viable cell counts of strains belonging to Lactobacillus species. Control wine showed no significant decrease in Lactobacillus count respect to day 0, but no Oenococcus species were detected after 14 days of MLF. Data are presented as mean ± SD and compared by one-way ANOVA followed by a Tukey post-test for multiple comparisons. Different letters (a–e) denote statistically significant difference (p < 0.05).
