Diversity of epothilone producers among S orangium strains in producer‐positive soil habitats

Diversity of epothilone producers among Sorangium strains in producer-positive soil habitats

Large-scale surveys show that the anti-tumour compounds known as epothilones are produced by only a small proportion of Sorangium strains, thereby greatly hampering the research and development of these valuable compounds. In this study, to investigate the niche diversity of epothilone-producing Sorangium strains, we re-surveyed four soil samples where epothilone producers were previously found...

Genetic Diversity among Plant Pathogenic Streptomyces Strains from Potato Fields in Northwest of Iran

Different species of Streptomyces are common in most types of soil. Some certain species are plant pathogenic especially on potato. This study was conducted to evaluate genetic diversity among some local Streptomyces spp. strains isolated from soil and infected tubers in potato farms in northwest of Iran. Repetitive DNA elements (BOX, ERIC and REP) as genetic markers were used for diversity stu...

Genetic diversity among Lassa virus strains.

The arenavirus Lassa virus causes Lassa fever, a viral hemorrhagic fever that is endemic in the countries of Nigeria, Sierra Leone, Liberia, and Guinea and perhaps elsewhere in West Africa. To determine the degree of genetic diversity among Lassa virus strains, partial nucleoprotein (NP) gene sequences were obtained from 54 strains and analyzed. Phylogenetic analyses showed that Lassa viruses c...

Diversity of Lactobacillus Strains in Iranian Traditional Wheat Sourdough

Background: Lactic acid bacteria play a key role in sourdough fermentation. Lactobacilli are the most important group of lactic acid bacteria in sourdough. Therefore, the main objective of this study was to identify Lactobacillus strains in Iranian traditional wheat sourdoughs as a basis for further studies on the technological applications in the production of typical breads. Methods: Fourtee...
