Fatty acid supplementation protects liaR-deficient Enterococcus faecalis from sodium dodecyl sulfate challenge. Shown are the averages ± standard deviations for n = 3. (A) Bile supplementation and challenge with 0.05% sodium dodecyl sulfate (SDS). All strains supplemented with 0.2% bile had statistically increased numbers of survivors versus those of their unsupplemented counterparts at all time points analyzed (P ≤ 0.0001). (B) Oleic acid (OA) supplementation and challenge with 0.05% SDS. All strains supplemented with 20 μg/ml OA had statistically increased numbers of survivors versus those of their unsupplemented counterparts at all time points analyzed (P < 0.05).
