title: Base composition of deoxyribonucleic acid isolated from Athiorhodaceae.
abstract: Guanine plus cytosine content of deoxyribonucleic acid ranged from 60.5 to 65.0% for five Rhodospirillum species and from 64.4 to 70.3% for six Rhodopseudomonas species. These values were compared to those of two Hyphomicrobiaceae and two hydrogen-oxidizing bacteria.
