Neighbor-joining tree based on 16S rRNA gene sequences showing relationships of soil streptomycetes with related, validly described Streptomyces species (accession numbers in brackets). In vitro inhibition against S. sudanensis, i.e.ratios between inhibition zone and colony diameter, are marked as I: Mean value and standard error. Evolutionary analysis was performed using MEGA7 software [16]
