نماتد مرکبات، tylenchulus semipenetrans، دارای گسترش جهانی بوده و یکی از عوامل سرخشکیدگی در باغ-های مرکبات محسوب می شود. آلودگی توأم نماتد با قارچ های بیمارگر گیاهی ثانویه، اثرات سوئی بر رشد گیاه خواهند داشت. به منظور بررسی تاثیر عوامل بیولوژیک روی مرگ و میر لاروها و تفریخ تخم نماتد در شرایط آزمایشگاهی و گلخانه 97 جدایه باکتری از فراریشه باغ های مرکبات شرق گیلان و غرب مازندران جداسازی شد. در آز...

Background: Streptomyces is one of the most important prokaryotic microorganisms, and their secondary metabolites have high antimicrobial and cytotoxic properties. Three-quarters of the antibiotics known to be produced by these bacteria. As a result, finding new effective compounds from these microorganisms can be a way to treat cancer. The aim of this study was to isolate and screen halophilic...

Streptomyces sp. US 24 and Streptomyces sp. TN 58, two strains producing interesting bioactive molecules, were successfully transformed using E. coli ET12567 (pUZ8002), as a conjugal donor, carrying the integrative plasmid pSET152. For the Streptomyces sp. US 24 strain, two copies of this plasmid were tandemly integrated in the chromosome, whereas for Streptomyces sp. TN 58, the integration was...

The response of two marine actinomycetes such as Streptomyces sp. MADO2 and Nocardiopsis sp. MADO3 to osmotic stress in minimal medium M63 and in glycerol-asparagine medium (ISP5) was studied. The two strains were moderately halophilic and the behavior of the strain Streptomyces sp. MADO2 and Nocardiopsis sp. MADO3 towards the salt stress was varied depends on the media composition and the sali...

Streptomyces sp. H-KF8 is an actinobacterial strain isolated from marine sediments of a Chilean Patagonian fjord. Morphological characterization together with antibacterial activity was assessed in various culture media, revealing a carbon-source dependent activity mainly against Gram-positive bacteria (S. aureus and L. monocytogenes). Genome mining of this antibacterial-producing bacterium rev...
