Growth profiles of <i>L. lactis</i> at different pH values.

<p>Growth was performed in CDM with 1% glucose (w/v) at 30 ^°C, with pH controlled at 6.5, 5.1 and 4.8. pH was controlled by addition of 10 M NaOH. Growth rate (μ): pH 6.5, 0.97±0.08 h^-1; pH 5.1, 0.63±0.04 h^-1; pH 4.8, 0.53±0.01 h^-1. Symbols: diamond, pH 6.5; triangle, pH 5.1; square, pH 4.8. Data shown are representative from at least two identical experiments.
