- Cultures were grown on synthetic medium containing 20 g L−1 glucose (pH 5). Values represent averages ± mean deviations of measurements on independent duplicate cultures. * (p < 0.05) denotes statistical significance of differences between strains IME324 and IMX774 at the same dilution rate and # (p < 0.01) indicates statistical significance of differences between analyses at different dilution rates in cultures of the same strain in Student’s t tests. Degree of reduction balances of steady-state analyses yielded electron recoveries between 99 and 101%
