Fig. 6: Effects of Mito-ortho-HNK and antibiotics on ATP.

E. faecalis were treated with Mito-ortho-HNK (a) or commonly used antibiotics (chloramphenicol [Cam], (b); ampicillin [Amp], c) as indicated. Panels (a–c) show the effects of Mito-ortho-HNK or antibiotics on E. faecalis proliferation shown as absorbance at OD600. Panels (d–f) show the effects of Mito-ortho-HNK or antibiotics on intracellular ATP levels as total luciferin luminescence. Data shown are the mean ± SD, n = 4.
