Abstract : Studies of the biochemical influence on electrochemical phenomena were initiated as part of a program leading towards the development of biochemical fuel cells. Biochemical systems selected for study include the biocatalysts Clostridium butyricum, a cell free extract of Escherichia coli, glucose oxidase, urease, Bacillus pasteurii, and L-amino acid oxidase. Cultural and physiological studies of the Clostridium butyricum and Escherichia coli were started. The effects of pH, temperature, substrate concentration and salt content on gas evolution by the Clostridium butyricum are reported. Physiological and cultural studies of Escherichia coli established that E. coli could be grown on a basal medium supplemented by yeast extract. Several urease coated electrodes were prepared by compressing carbon mixtures. The evidence indicates the need of a binder to increase the mechanical strength of the electrode and a catalyst for the oxidation of the ammonia formed. (Author)
