Evidence for a dissimilatory plasmid in Azotobacter chroococcum.
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. The cured cells did not utilize 2,4-D and its intermediates and lacked the plasmid DNA.
