Nitrogen fixation is advantageous in microbial competition when bioavailable nitrogen is scarce, but has substantial costs for growth rate and growth efficiency. To quantify these costs, we have ...

Researchers have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this ...

Azotobacter insignis Derx has been isolated from flowing fresh water streams in Vermont and appears most frequently associated with submerged aquatic plants. This is the first report of this strictly ...
