Isolation of nitrogen-fixing bacteria containing molybdenum-independent nitrogenases from natural environments

Appl Environ Microbiol. 1999 Sep;65(9):4223-6. doi: 10.1128/AEM.65.9.4223-4226.1999.

Abstract

Seven diazotrophs that grow well under Mo-deficient, N(2)-fixing conditions were isolated from a variety of environments. These isolates fall in the gamma subdivision of the class Proteobacteria and have genes that encode the Mo nitrogenase (nitrogenase 1) and the V nitrogenase (nitrogenase 2). Four of the isolates also harbor genes that encode the iron-only nitrogenase (nitrogenase 3).
