A neighbour-joining phylogenetic tree based on the 16S rRNA gene sequences, showing the relationship between the distinctive antimicrobial actinobacteria isolated from termite nests and recognized members of the class Actinobacteria. Thermopolyspora flexuosa DSM 43186T was used as an outgroup. Bootstrap values (>50%) based on 1000 replications are shown at the branch nodes. Bar = 0.01 substitutions per nucleotide position. The accession numbers of the gene sequences are indicated in parentheses. The phylogenetic tree was categorized into 4 families: (I) Streptomycetaceae, (II) Micromonosporaceae, (III) Nocardiaceae, and (IV) Pseudonocardiaceae.
