Fatty acid profiling in WT E. faecalis. Changes in the relative abundance for (A) saturated and (B) unsaturated fatty acids after the addition of exogenous Na₂S to cell cultures. (C) The ratio of total saturated to unsaturated fatty acids for Na₂S treated cells vs. untreated wild-type cells. Values represent the means ± S.D. derived from the results of biological triplicate experiments, with statistical significance established using a paired t-test relative to the endogenous, time 0 (*** p ≤ 0.001, ** p ≤ 0.01, * p ≤ 0.05).
