Abstract
Eikenella corrodens 33EK(L), a clinical isolate, was assayed for its ability to utilise amino acids as substrates in the reduction of nitrate to nitrite. The metabolism of proline, glutamate, serine and glutamine was found to result in relatively high rates of nitrate reduction. The ability of cells to metabolise these amino acids from a variety of small peptides was also determined. E. corrodens was found to possess a relatively specific proline aminopeptidase as well as a putative carboxypeptidase activity for glutamate. Energy production in this organism appears to be via oxidative deamination of these key amino acids linked to a respiratory chain, with nitra...
