Growth test of the S. cerevisiae wild type BY4741 (1), BY4741sdh1Δ (2), and BY4741sdh1bΔ (3) strains and K. lactis MW179-1DKlsdh1Δ (4), MW179-1D (5), GG1993 (Klpda1Δ) (6), and CBS2359/152 (7). The plates are minimal media containing glucose or lactate. GG1993 is an isogenic derivative of CBS2359 (50). The initial cell concentration was 2 × 107 to 4 × 107 with a 10-fold dilution.
