Nitrogen fixation by Vibrio parahaemolyticus and its implications for a new ecological niche.
A Vibrio parahaemolyticus strain isolated from the rhizosphere of the ecosystem dominant estuarine grass, Spartina alterniflora, was characterized and shown to carry nifH, the gene encoding the nitrogenase iron protein, and to fix N(2). Nitrogen fixation may contribute substantially to the adaptability, niche breadth, and ecological significance of V. parahaemolyticus.
