The influence of transmembrane ion fluxes on mycoplasma membrane potentials was studied. Fluorescence intensity of potential-sensitive carbocyanine dyes was calibrated vs. electric membrane potential. Potassium and sodium ion diffusion potentials significantly contributed to mycoplasma membrane potential. Chloride ions were obviously freely permeable across mycoplasma membranes. Under growth conditions the mycoplasma membrane potential was estimated to be delta psi = - 80 mV.
研究了跨膜离子通量对支原体膜电位的影响。对电位敏感的羰花青染料的荧光强度根据膜电位进行了校准。钾离子和钠离子扩散电位对支原体膜电位有显著贡献。氯离子显然可自由透过支原体膜。在生长条件下,支原体膜电位估计为Δψ = -80 mV。
