Richard John obtained his Ph.D. (1993) from the University of Wollongong, Australia, dealing with the chemical and electrochemical properties of heterocyclic conducting polymers. Fellowships from the Royal Society and the Australian Research Council allowed him to carry out post-doctoral studies at Oxford University and at the University of Wollongong. In 1996 he was appointed as a lecturer at Griffith University. From 2000–2004 he was the elected Chair of the Electrochemistry Division of the Royal Australian Chemical Institute. His research interests include the development of new analytical methodologies for environmental and clinical analysis, the electrochemistry of new materials, and the education and communication of science. He has published over 50 international peer-reviewed research articles as well as several book chapters and two patents.

Kristy Morris is a Ph.D. student at Griffith University, who has just submitted her thesis for examination. Her research studies have focussed on the development of a rapid assay for biochemical oxygen demand employing ferricyanide-mediated microbial reactions. She has so far co-authored five papers in this area. Kristy is currently pursuing post-doctoral opportunities in the USA.

Huijun Zhao is an electrochemist, having obtained his Ph.D. in 1994 from the University of Wollongong. He currently holds an Associate Professor position at Griffith University. His research activities include electromembrane separations, energy storage materials/secondary batteries, photocatalysis, biosensing techniques, and on-line environmental analytical methods. He has published in excess of 50 papers in international peer-reviewed journals as well as several patents in these fields.

Abstract

The ability of microorganisms to use ferricyanide as an alternative electron acceptor for respiratory processes has been known for nearly 100 years. More recently, the use of ferricyanide-mediated bioreactions for environmental monitoring has received much attention. This paper reviews the recent developments of these mediated microbial processes for rapid biochemical oxygen demand analysis and direct toxicity assessment during the past five years. The ability of eukaryotic microorganisms to use ferricyanide as an alternative electron acceptor for a range of applications is also described.
