  1. *Data are expressed as a percentage of the growth rate (h-1) obtained in the absence of bile, which was assigned a value of 100%. Means ± standard deviations of three independent experiments with three replicates per assay are given. Means in the same column with different letters (a through f) differ (p < 0.05).
