Table 4. Measured intra- and extracellular alanine and pyruvate concentrations. Alanine and pyruvate concentrations (pmol/mg of dry cells) observed for cocultures (CC) and monocultures of M. maripaludis (MmS) and D. vulgaris (DvH). Wild type (WT) or alanine transporter deficient (ΔalsT) strains were used.
