Leptospirillum: a study of the nitrogen fixing capabilities
MetadataShow full item record
This project sought to determine the response of Leptospirillum species subject to conditions without soluble nitrogen. The most significant outcome of this work was the identification of the nifHDK genes in L. ferriphilum and observations of its continued ability to survive in environments without soluble nitrogen. The sustained proliferation of all three Leptospirillum species studied, combined with the structural analysis of these genes, provides evidence of functional nitrogen fixation in each of these species.

Upregulation of the Nifhdken Operon in Leptospirillum Species Subjected to Soluble Nitrogen StarvationCorbett, Melissa; Mutch, Lesley; Watkin, Elizabeth (2008)Background: Members of the genus Leptospirillum routinely dominate bioleaching systems. Understanding their metabolic complexity is necessary for the improvement of bioleaching technologies. Nitrogen is an essential element ...
