| Summary: | Streptomyces species have been an important source of bioactive secondary metabolites and clinically
useful for antibiotic production, including fosfomycin, daptomycin, oxytetracycline, streptomycin, and
chloramphenicol. The main objective of this study was to isolate actinomycetes, especially Streptomyces
from 8 soil samples that collected from two different places, which are districts in Sulaimani governorate,
Kurdistan Region of Iraq. Totally, 30 diagnostic tests were carried out for representative of isolated
Streptomyces depending on the color groups. The 16Sr DNA gene was sequenced, for ten isolated
test strains were amplified with 2 universal primers after extraction of genomic DNA, only 8 of them
were successfully sequenced. Phylogenetic analysis of 8 test strains carried out using base sequences
of 16Sr DNA genes in the core genome. Four of isolated test strains were identified as a Streptomyces
fulvissimus, and others were nominated as a Streptomyces anulatus. The obtained sequence data were
compared with the sequence data of the closest related species in the international databases using
EzTaxon Server program and (%) similarities were determined. Finally, phylogenetic analysis indicated
that isolated test strains were nominated as (H001, H002, H003, and H004), which recognized members
of the S. anulatus and the similarity with their type strain is 99.93%. Whereas, other four isolated
test strains, including D001, D002, D003, and D004 recognized as members of the S. fulvissimus
and similarity with their type strain is 100%. |
