Aras river has a very important place in terms of geographical and ecological sense. It
is thought that the detection, isolation, diagnosis and characterization of Streptomyces diversity
in the Aras river will contribute to the scientific world in the fields of microbiological and
molecular biology and genetics. Streptomyces species have a very important place for the
scientific world, because there are many important substances produced by these bacterial
species, especially antibiotics. Samples taken from Erzurum Horasan, Kars Karakurt and Iğdır
Tuzluca regions where Aras river passes were examined in terms of Streptomyces diversity. The
pH and moisture ratios of the sediment samples taken from the determined localities were
determined. Isolation, purification and color group determination studies were performed using
Bennet's Agar and M65 media. Biochemical, phenotypic and molecular tests were applied to
diagnose these bacterial groups. Spore chain morphology of the isolates determined according to
the color group was visualized (SEM). Sequence analysis of 16 S rDNA gene regions of bacteria
to be isolated microbiologically was performed. Then, the obtained sequences were compared
with the GenBank data, and the molecular affinity and similarity ratios of the isolated bacteria
were obtained.
