Production of Plant Growth Substances by Azotobacter chroococcum [PDF]
SUMMARY: Cultures of Azotobacter chroococcum strain A6 were grown for 14 days in a nitrogen-deficient mineral medium, the supernatant fluid and bacteria extracted and examined by paper partition chromatography with two solvent systems which separate authentic gibberellin (GA3) and indolyl-3-acetic acid (IAA).

The Effect of Alkylresorcinol on Lipid Metabolism in Azotobacter chroococcum
We studied the effect of exogenous alkylresorcinols on the lipid metabolism of Azotobacter chroococcum. We observed that when 5-n-pentadecylresorcinol was present in the growth medium, the more endogenous alkylresorcinols were synthesized. Concurrently, a drop in the amount of phospholipids was observed.

Interaction of Piriformospora indica with Azotobacter chroococcum. [PDF]
AbstractMicrobial communities in rhizosphere interact with each other and form a basis of a cumulative impact on plant growth. Rhizospheric microorganisms like Piriformospora indica and Azotobacter chroococcum are well known for their beneficial interaction with plants. These features make P. indica /A.

The Cytology and Life-cycle of Azotobacter chroococcum [PDF]
SUMMARY: Azotobacter chroococcum exists in two cytologically distinct vegetative forms. In one the appearance is that of a typical bacterial resting cell, with a large vesicular nucleus. In the other the cytoplasm appears homogeneously vacuolated and refractive; this is correlated with a high lipid content.

Azotobacter Genomes: The Genome of Azotobacter chroococcum NCIMB 8003 (ATCC 4412). [PDF]
The genome of the soil-dwelling heterotrophic N2-fixing Gram-negative bacterium Azotobacter chroococcum NCIMB 8003 (ATCC 4412) (Ac-8003) has been determined. It consists of 7 circular replicons totalling 5,192,291 bp comprising a circular chromosome of 4,591,803 bp and six plasmids pAcX50a, b, c, d, e, f of 10,435 bp, 13,852, 62,783, 69,713, 132,724 ...

Evidence for a dissimilatory plasmid inAzotobacter chroococcum [PDF]
Dissimilation of 2,4-dichlorophenoxyacetic acid in Azotobacter chroococcum is plasmid mediated. This dissimilatory plasmid designated pMSB1, was effectively cured by mitomycin C. The plasmid was transferred to another strain of Az. chroococcum at a frequency of 2.4 x 10(-3) transconjugants/donor cell.

Functional characterization of three Azotobacter chroococcum alginate-modifying enzymes related to the Azotobacter vinelandii AlgE mannuronan C-5-epimerase family. [PDF]
Bacterial alginate initially consists of 1-4-linked beta-D-mannuronic acid residues (M) which can be later epimerized to alpha-L-guluronic acid (G). The family of AlgE mannuronan C-5-epimerases from Azotobacter vinelandii has been extensively studied ...
