Abstract

The membrane potential, delta psi, of various yeasts estimated from the distribution of tetraphenylphosphonium cations ranged from -50 to -120 mV, depending on species, incubation conditions and technique of measurement. Values obtained directly with a microelectrode in Endomyces magnusii were consistently lower than those determined indirectly.

摘要

根据四苯基鏻阳离子的分布估算，各种酵母的膜电位（Δψ）在-50至-120 mV之间，具体数值取决于酵母种类、培养条件和测量技术。用微电极直接测得的大形内孢霉的数值始终低于间接测定的值。
