The taxonomy of Streptomyces and related genera.

چکیده
The streptomycetes, producers of more than half of the 10,000 documented bioactive compounds, have offered over 50 years of interest to industry and academia. Despite this, their taxonomy remains somewhat confused and the definition of species is unresolved due to the variety of morphological, cultural, physiological and biochemical characteristics that are observed at both the inter- and the intraspecies level. This review addresses the current status of streptomycete taxonomy, highlighting the value of a polyphasic approach that utilizes genotypic and phenotypic traits for the delimitation of species within the genus.

متن کاملAntibacterial and antitumor potential of actinomycetes isolated from mangrove soil in the Maowei Sea of the southern coast of China
Mangroves are the tidal forest existing in the intertidal zone and usually considered as the special marine ecosystem. In the present study, 452 actinomycetes were recovered from nine diferent sites at Maowei Sea Mangrove Reserve in Qinzhou (Guangxi province, China). Among them, Seventy-four strains were purified for 16s RNA gene sequencing and further characterization. The results indicated th...

Abundance and multilateral extension of prominent genus and species of Brachiopoda in the majority of sedimentation series of the Late Devonian have been observed in all parts of Iran. The variability and rapid change in this respect has made it possible to delineate different lines of orthogenetism, biozonation and present biostratigraphical models at the sub-stage level. These characteristics...
