In our study, we were able to detect the frequently isolated genus Streptomyces with a clear antibacterial activity.
The comparison of morphological and physiological characteristics with known actinomycetes reported in Bergey's Manual of Systematic Bacteriology (Whitman et al., 2012; Atalan et al., 2000) suggested that these strains belong to the genus Streptomyces. Nucleotide BLAST analysis showed that strain HU-9 had 98% similarity with Streptomyces puniceus and HU-10 had 99% similarity with Streptomyces sp.
The genus Streptomyces is the most frequently isolated from soils (Xu et al.
The genus Streptomyces possessed the highest proportion of isolates with antimicrobial activities.
About 80% of these are made by members of the genus Streptomyces (Demain, 2009).
The study confirmed that all of the tested strains belonged to the genus Streptomyces and 7 out of 10 strains could be identified to the species level.
Different strains belonging to the genus Streptomyces are known to contain cellulases (25), but it is not clear if S.
However, the application of criteria, morphological features such as sporangium formation in submerged liquid culture and chemical composition of certain cell constituents (such as cell wall) in the characterization of these a typical isolates is therefore not sufficient to identify these isolates as members of the genus Streptomyces. Genetic and phenotypic diversity among Streptomyces isolates are well known (24) but ecological and systemic assessments have been problematic because readily used morphological, biochemical or molecular markers have largely been locking.

Covering in turn virulence mechanisms and important bacterial diseases in agriculture, they discuss such aspects as fimbrial and afimbrial adhesins involved in bacterial attachment to surfaces, high-throughput DNA sequencing technology as a tool in understanding plant-pathogen bacteria, Candidatus liberibacter species and related diseases, virulence mechanisms of plant-pathogen Ralstonia species, and mechanisms of pathogenicity and the emergence of new plant-pathogen species in the genus Streptomyces.

Comparison between the characteristics of the active actinomycete isolate MM10 above described with the former isolates indicated that it belongs to the genus Streptomyces. The 16S rDNA sequence was compared to the GeneBank database in the National Center for Biotechnology Information (NCBI) using the BLAST program (Fig.
Cultural and morphological characterization of the three active isolates using a light microscopy showed that they belong to the genus Streptomyces. Branching filaments, abundant aerial mycelia, and long chains of small rectiflexible spores are visible, all of which are characteristic of Streptomyces sp.
Among them, three bioactive isolates were selected based on their larvicidal and insecticidal activity and were identified as species belonging to the genus Streptomyces by analyzing their morphological characteristics (Locci, 1989) and by preliminary physiological testing.
The phylogenetic relations of taxa in the trees constructed from the largely conserved 16S rRNA gene sequences confirmed that the classic phenotypic, and largely morphological, characteristics used for classification schemes for species of the genus Streptomyces are generally quite useful for species identification and grouping of similar taxa, including spore colour and spore surface ornamentation [11].
