Mediator compounds for the electrochemical study of biological redox systems: a compilation

Electrochemical Measurement of Yeast Cell Density and Vitality Using 2,3,5-Trimethyl-1,4-benzoquinone and Effect of Ethanol on the Metabolism of Quinone by Yeast Cells

“…It is well-known that microbial cells reduce various chemical mediators such as quinones, Fe(CN) 6 3Ϫ , phenazines, and 2,6-dichlorophenol indophenol (Fulzt & Durst, 1982). Thus, techniques based on the metabolism of chemical mediators for the measurement of microbial cell density have been reported (Kondo et al, 2002;Miki et al, 1994;Nishikawa et al, 1982;Nishimoto & Yamashoji, 1994;Rossetti et al, 1994).…”

Photoelectrochemical cells based on photosynthetic systems: a review

“…Primary processes of photosynthesis have high quantum yield reaching almost 100%, but the energy storage efficiency can reach as high as about 27% under ideal conditions, and much less under non-ideal ones (Fultz and Durst, 1982). This value is comparable to the efficiency of the modern silicon-based solar panels operating with an efficiency of approximately less than 20%.…”

Extracellular Electron Transfer in in situ Petroleum Hydrocarbon Bioremediation

“…On the other hand, electronwithdrawing sulphone groups facilitate reduction, as is reflected by an increasing potential along with increasing sulphonation for anthraquinone (AQ). Here, an increase of the compounds' potential from -225 mV for AQ-2-sulphonate by almost 40 mV to -184 mV for AQ-2,6-disulphonate is connected to the addition of one sulphone group (Fultz and Durst, 1982). The location of electron donating and accepting groups in respect to the keto-groups also determines the shuttles' stability in recurring redox-processes (Watanabe et al, 2009).…”

“…Several publications are dedicated to the description of the redox-properties of a wide range of mediators (Bird and Kuhn, 1981;Fultz and Durst, 1982;Meckstroth et al, 1981).…”
