Non-cyanobacterial nifH phylotypes in the North Pacific Subtropical Gyre detected by flow-cytometry cell sorting

, 2013
In contrast to cyanobacteria, the significance of bacteria and archaea in oceanic N2 fixation remains unknown, apart from the knowledge that their nitrogenase (nifH) genes are diverse, present in all oceans and at least occasionally expressed.

Nucleotide sequence of the nifH gene coding for nitrogen reductase in the acetic acid bacterium Acetobacter diazotrophicus

, 1998
The nifH gene sequence of the nitrogen-fixing bacterium Acetobacter diazotrophicus was determined with the use of the polymerase chain reaction and universal degenerate oligonucleotide primers. The gene shows highest pair-wise similarity to the nifH gene

Amplification, cloning, and sequencing of a nifH segment from aquatic microorganisms and natural communities

, 1991
By use of the polymerase chain reaction and degenerate oligonucleotide primers for highly conserved regions of nifH, a segment of nifH DNA was amplified from several aquatic microorganisms, including an N2-fixing bacterium closely associated with the ...

Diversity, Distribution, and Expression of Diazotroph nifH Genes in Oxygen-Deficient Waters of the Arabian Sea

, 2012
The Arabian Sea oxygen minimum zone (OMZ), the largest suboxic region in the world\u27s oceans, is responsible for up to half of the global mesopelagic fixed nitrogen ( N ) loss from the ocean via denitrification and anammox.
