Dependence of growth on glucose is due to citrate itself rather than the coincidental
addition of sodium. The ratio and error for growth parameters was calculated by fitting a log-linear
model with the strain:media interaction terms and block as the dependent variables.
Both the relative (A) growth rate and (B) yield on glucose for the three lineages that were strongly stimulated by the addition
of sodium citrate (black circles) could be achieved by simply adding citric acid (white
diamonds). Values represent the mean and 95% confidence intervals for the ratio of
growth of that strain on glucose with the supplement to growth without.
