Table S2. Actinobacterial strains isolated in this study. 64 morphologically distinct isolates were divided into 12 phenotypic groups. The 16S rDNA genes of all the isolates in phenotypic groups 1-5 and 9-12, considered as putative rare actinobacteria, and of the representative isolates in groups 6-8, considered as putative Streptomyces isolates
