Short Communications

Summary

A microbiol culture able to grow in the absence of oxygen with nitrilotriacetate (NTA) as the sole source of carbon and energy was enriched from river sediment. Growth was strictly dependent on the presence of nitrate and the results indicate that nitrate was exclusively used as the electron acceptor and was reduced to dinitrogen (N2). The stoichiometry of anaerobic NTA degradation by the enrichment culture was determined.

Key words
