FIG. 1.

Evolutionary distance tree of the bacterial domain showing an overview of culturable bacterial diversity for the Ellinbank soil samples at the family level. All family-level groupings (shown as wedges) were supported by bootstrap resampling (bootstrap proportion values, >75%). The phylogenetic depth of each of the phyla to which the families belong is shaded. Where the new isolates are the first isolated representatives of a proposed family, the family name is shown in boldface type. The 16S rRNA gene sequences of Sulfolobus acidocaldarius (GenBank accession no. D14876) and Methanococcus vannielii (accession no. M36507) and the hot spring 16S rRNA gene sequence pJP27 (accession no. L25852) were used as outgroups (data not shown) in the analysis. Bar, 0.05 change per nucleotide.
