Abstract:

Investigation of the formic acid bioanode using E. coli as the biological catalyst was continued. The effect of varying the pH and ionic strength of the supporting anolyte, the number of bacteria, and the addition of methylene blue are reported. Attempts to inhibit the formation of the hydrogenlyase system, which degrades the formic acid, in E. coli were largely unsuccessful. However, a new organism, Pseudomonas formicans, was substituted. This organism carries out a mixed acid fermentation similar to that of E. coli, but is not capable of producing a hydrogenlyase system. Preliminary bioelectrochemical studies with this organism in an integrated cell, have produced current densities of 5 mAsq cm at a polarization of only 0.26 volt. AuthorXGAIEE
