Fig. 6. (A) Potassium ion release from E. coli cells 10 minutes after treatment with DMSO, gramicidin-D (control) and benzyl C8–C14 hydraphiles (compounds 1–4). The total potassium pool of E. coli was determined by boiling the bacteria at 100 °C for 30 minutes. (B) Change in extracellular potassium concentration over 12 minutes of treatment with various concentrations of benzyl C14 hydraphile (4). Error bars represent standard deviation in three trials.
