Abstract

SUMMARY: The DNA base composition of 14 authentic strains of the genus , determined by caesium chloride density gradient centrifugation, was found to vary from 51 to 68 mole % guanine+cytosine (G + C). The mole % G + C values for the various species are as follows: and 51-52, and 56-57, and and 62-68. Another group of chemoautotrophic bacteria, the nitrifiers and , were found to have a G + C content of 52 and 65%, respectively. The results are compared with other types of taxonomic studies made with these and related bacteria.
