Chemotactic Behavior of Azotobacter vinelandii.

Restoration by ubiquinone of Azotobacter vinelandii reduced nicotinamide adenine dinucleotide oxidase activity.

Extraction with pentane virtually abolished reduced nicotinamide adenine dinucleotide oxidase activity in small particles from Azotobacter vinelandii, but activity was largely restored by added ubiquinone.

Technique for isolating phage for Azotobacter vinelandii.

An enrichment technique was developed whereby azotophage could readily be isolated after inoculation of soil sites with Azotobacter vinelandii.

Complete Genome Sequences of Azotobacter vinelandii Wild-Type Strain CA and Tungsten-Tolerant Mutant Strain CA6

We report the complete genome sequences of Azotobacter vinelandii mutant strain CA6 and its parent wild-type strain, CA. When fixing nitrogen, strain CA6 displays slow growth and impaired molybdate uptake, tolerance to tungstates, and production of hydrogen gas, compared to results for strain CA. Comparing these genome sequences may provide a genetic basis for these mutant phenotypes.

Azotobacter vinelandii mutS: nucleotide sequence and mutant analysis.

An Azotobacter vinelandii homolog to the Salmonella typhimurium mutS gene was discovered upstream of the fdxA gene. The product of this gene is much more similar to S. typhimurium MutS than either is to the HexA protein of Streptococcus pneumoniae. An A. vinelandii delta mutS mutant strain was shown to have a spontaneous mutation frequency 65-fold greater than that of the wild type.
