Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...

conclusions this paper may serve as a guide to screening, isolation, and cultivation of more new mtb. the new isolated strain opens up good opportunities for biotechnological applications such as medicine to bioremediation processes due to its unique abilities. results the results revealed a correlation of important physicochemical factors such as ph and iron with growth and blooms of these bac...

Analysis of 16S rRNA gene sequences has become the primary method for determining prokaryotic phylogeny. Phylogeny is currently the basis for prokaryotic systematics. Therefore, the validity of 16S rRNA gene-based phylogenetic analyses is of fundamental importance for prokaryotic systematics. Discrepancies between 16S rRNA gene analyses and DNA-DNA hybridization and phenotypic analyses have bee...

In the past, bacterial phylogeny relied almost exclusively on 16S rRNA gene sequence analysis. More recently, multilocus sequence analysis has been used to infer organismal phylogenies. In this study, the dnaJ chaperone gene was investigated as a marker for phylogeny studies in alphaproteobacteria. Preliminary analysis of G+C contents and G+C3s contents (the G+C content of the synonymous third ...
