Low frequency alternating electric fields inhibit lactose uptake in Kluyveromyces marxianus1

Abstract

Frequency-dependent lactose uptake via the H⁺/lactose symporter in an externally applied low-intensity alternating electric field was demonstrated, using tracer flux experiments. The uptake of radiolabeled lactose was significantly inhibited with the electric field-strength of 30 V/cm and at frequencies below 10 Hz.
