[Content of nitrogen bases in the DNA of carboxide bacteria]

The composition of nitrogen bases was determined in total DNA of live strains of carboxide bacteria belonging to the genera Pseudomonas, Comamonas, Seliberia (Agrobacterium), Achromobacter. Considerate differences in the nucleotide composition of DNA of the studied bacteria confirm that they indeed belong to different genera. At the same time, the content of GC pairs in DNA of these bacteria is within the range found for the corresponding genera by other authors.
