Abstract
Four strains of A. brasilense, including strain 7000 (ATCC 29145), and 5 strains of A. lipoferum, including strain Br17 (ATCC 29709), were examined for the presence of plasmids. All the strains harbored 1-5 plasmids in which MW ranged from 3.5- > 300 Mdaltons. No relationships between the plasmids and phenotypic properties (such as N2 fixation, substrate utilization, drug resistance and lysogenic state) have been established. Of the 9 strains, 6 were lysogenic. Phage production was inducible by mitomycin C in these 6 strains. An icosahedral phage was purified from strain 7000.
