Correlations between the Topt values of archaeal strains and the G+C contents of their 16S rRNA genes. The archaeal strains were randomly chosen from various publications in which the phylogeny and taxonomy of microorganisms were reviewed (2, 32). The 16S rRNA gene sequences of the strains were obtained from the DDBJ/EMBL/GenBank database. The G+C contents of the 16S rRNA gene sequences were calculated by using Genetyx-Mac.
