Effect of 1-octanol and 1-decanol on the intracellular K+ concentration of nonadapted resting cells of P. putida DOT-T1E. To allow a comparison of the effects of the alkanols on membrane permeabilization, both compounds were added in concentrations that caused a 50% (1-octanol, 0.0225 [□], and 1-decanol, 0.004 [▪] [vol/vol]) and 100% (1-octanol, 0.03 [⋄], and 1-decanol, 0.0045 [⧫]) (vol/vol) growth inhibition of P. putida DOT-T1E. •, control.
