    Characterization of the deoxyribonucleic acid of various strains of halophilic bacteria.

    Abstract

    Bacteria classified as extreme halophiles, in the genera Halobacterium and Halococcus, contain deoxyribonucleic acid (DNA) which displays two components in a CsCl equilibrium density gradient. The base composition of the major DNA component ranges from 66 to 68% guanine plus cytosine (GC), whereas that of the satellite DNA comprising some 11 to 36% of the total, is between 57 and 60% GC. Purification of the bacterial cells in a CsCl density gradient and other more conventional strain purification procedures both indicated that the presence of the satellite DNA component is not a result of mixed cultures.
