Abstract: Fontana-Ayoub M, Fasching M, Eigentler A, Laner V, Gnaiger E (2015) O2k-Fluorometry: Amplex® UltraRed using freeze-dried baker’s yeast. Mitochondr Physiol Network 18.06(04):1-4 »Versions
Respiration and hydrogen peroxide production of yeast was studied under hypoxic and hyperoxic conditions, and after stimulation of respiration by glucose using the O2k-Fluorescence LED2-Module. Extracellular H2O2-production by intact yeast cells was a pronounced function of environmental oxygen concentration (Fig. 1). Oxygen kinetics of respiration resembled closely but not fully that of isolated mitochondria, indicating that extracellular oxygen levels provide a good approximation of intracellular conditions, and intracellular oxygen gradients are small. Stimulation of respiration was pronounced with the extracellular substrates glucose and ethanol, and with uncoupler titrations. In contrast, these additions exerted a minor effect on extracellular H2O2 production (Fig. 2).
