Evidence for nitrogen fixation by "Dehalococcoides ethenogenes" strain 195

Abstract

Genome annotation of the chlorinated ethene-respiring "Dehalococcoides ethenogenes" strain 195 indicated the presence of a complete nitrogenase operon. Here, results from long-term growth experiments, gene expression, and (15)N(2)-isotope measurements confirm that strain 195 is capable of fixing atmospheric dinitrogen when a defined fixed-nitrogen source such as ammonium is unavailable.
