Carbohydrate consumption can vary according to the strains associated. Percentages of lactose, sucrose, and raffinose consumed in mono- and cocultures of LAB donor and receiver strains during 24 h of incubation at 30°C are shown. Percentages were calculated as a ratio of the amount in the carbohydrate after fermentation relative to the amount of the noninoculated media used as a control: CDM PROT was used as the control for the donor strains Efa2412, Lla2125, Lla244 and the cocultures, and CDM TRYP was used for the receiver strains Lla450, Lpl465, and Lpl1524 monocultures. Initial concentrations, in grams per liter, were as follows: lactose, 4.78 ± 0.50; sucrose, 4.03 ± 0.21; and raffinose, 4.63 ± 0.23. Different letters indicate significant differences between cultures (P < 0.05).
