Interaction of Piriformospora indica with Azotobacter chroococcum. [PDF]

Sci Rep, 2015
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]

Journal of General Microbiology, 1953
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.

Evidence for a dissimilatory plasmid inAzotobacter chroococcum [PDF]

FEMS Microbiology Letters, 1989
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.
