Abstract: In this study, soil samples from the roots and peripheral regions of some agricultural plant species growing in the Van region (such as sainfoin, bean, malus, wheat and sugar beet) were collected between May and June 2004 and 139 strains of Streptomyces bacteria were isolated from these samples. Moreover, researchers determined the physicochemical characteristics of these soil samples. Streptomyces bacteria were color-grouped and the Diaminopimelic Acid (DAP) forms were detected followed by the determination of then phenotypic characteristics. When these isolates were divided into 39 color groups, 20 strains were found to contain L-DAP and therefore were confirmed as members of the genus Streptomyces. The species were identified using the TAXON Software and similarity dendrograms were constructed by the Unweighted Pair-Group Method with an Arithmetic average (UPGMA) cluster analysis using the Multi-Variate Statistical Package (MVSP 3.1). Genomic DNA was isolated from these bacteria and 16S rDNA gene was amplified by PCR followed by restriction digestion with Bsp143I, HaeIII, MnlI and SphI for Restriction Fragment Length Polymorphism (RFLP) analysis. In the dendrogram obtained at the end of the RFLP analysis, four groups of two or more members and six 1-member groups were established according to the similarity ratio criterion.
