Five different Brazilian soils were examined for the incidence of Bacillus nitrogen fixers. These counts were set in relation to the total spore count, and the number of facultative anaerobic spores. Twenty-four Bacillus strains were isolated using media lacking a nitrogen source, identified and their acetylene-reducing ability was determined. Eighteen of these strains were identified asB. polymyxa, and the other 6 were related to this species, but were different in some taxonomical tests. Of… CONTINUE READING
