Technique for isolating phage for Azotobacter vinelandii.

Relationship of encapsulation and encystment in Azotobacter.

0. Wyss, M. Neumann, and M. Socolofsky (J. Biophys. Biochem. Cytol. 10:555, 1961) have shown by electron micrographs of ultrathin sections that the mature cyst of Azotobacter vinelandii strain 12837 can be divided into three main structural entities: the exine or cyst coat, the outermost laminated structure; the intine, a rather homogeneous layer, which, upon artificial rupture, appears to have...

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.

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.

Stimulation of Agrobacterium tumefaciens Growth by Azotobacter vinelandii Ferrisiderophores.

Azotobacter vinelandii stimulated the growth of Agrobacterium tumefaciens H2, H23, H24, H27, and ATCC 15955 on media containing insoluble iron sources. The Azotobacter vinelandii siderophores appeared to promote Agrobacterium tumefaciens growth by solubilizing mineral iron, and the ferrisiderophores so formed then acted as iron sources for Agrobacterium tumefaciens. Agrobactin, the Agrobacteriu...
