Diversity Investigation of Actinomycetes Isolated from Radiation-polluted Soil

Abstract:

One hundred and fifty two actinomycetes were isolated from forty two radiation-polluted soil samples, using six different isolation media. Sixty cultures were chosen for 16S rRNA gene sequence and systematic analysis, which based on their morphology and ARDRA. Results of 16S rRNA gene sequences blasting showed that the strains were assigned to 12 recognized genera of actinomycetes, most of them fall within Streptomyces genus and a great deal of strains belonged to rare actinomycetes, which indicated a rich diversity of actinomycetes in the radiation-polluted soil.
