Abstract
Ferricyanide mediated microbial reactions were employed for the rapid
determination of the biochemical oxygen demand (BOD) of a range of synthetic
and industrial wastewater samples. By replacing oxygen with a highly soluble
artificial electron acceptor, such as ferricyanide, the rates of microbial catabolism
were greatly enhanced, providing the basis of a rapid BOD assay. The microbial
species used in this study were Klebsiella oxytoca, Serratia liquefaciens,
Pseudomonas aeruginosa, Saccharomyces cerevisiae and Enterobacter cloace.
Each species, as well as a synthetically prepared consortium of the five species,
were compared in their ability to rapidly degrade organic samples in the presence
of ferricyanide. The microbial consortium demonstrated a greater extent and
