Electrochemical Detection of Yeast Responses to Catabolizable Molecules

Abstract

Cells harvest energy from energy-rich molecules by oxidation of the molecule and the subsequent transfer of electrons to catabolic redox compounds. This transfer can be intercepted by artificial redox compounds (mediators), and the reduction of the mediator can be easily monitored by several electrochemical techniques. This work describes the use of steady-state voltammetry to monitor the catabolic responses of two yeast species to specific molecules.
