Identification of thermophilic Streptomyces strains. Phylogenetic tree for 11 newly identified strains and some known mesophilic and thermophilic Streptomyces species (Genbank numbers in parentheses). The tree is drawn to scale using the neighbor-joining method, with branch lengths in the same units as those of the evolutionary distances. Numbers next to the branches are the percentage of replicate trees (the bootstrap test is 500 replicates).
