The in vitro antimicrobial activity of the essential oil isolated from the aerial parts of Cymbopogon Olivieri (Boiss.) Bor, an aromatic grass of Iran was tested against three Gram-negative and four Gram-positive bacteria and also three fungi. The results of the bioassays showed that the oil has a remarkable antimicrobial activity. Bacillus subtilis and Candida albicans were more sensitive to t...

In this paper, synthesis and antimicrobial properties of cationic dye were investigated. 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide was reacted with 1-bromobutane as the alkylating agent and a cationic dye was obtained. The final product was purified by column chromatography method. The chemical structure of the novel cationic dye and its intermediates was chracterisized by using F...

Seven reported xanthate ligands and their new Fe(II) complexes of formulaNa[Fe(R-OCSS)3], where R is ethyl-, propyl-, butyl-, pentyl-, Hexyl-, heptyl- and octyl-xanthate have been synthesized. They have been characterized using elemental analysis, molar conductance, FT-IR, UV-Vis and 1H NMR spectroscopic techniques and melting-, decomposition-points for ligand...

concern about the rising prevalence of antibiotics-resistant strains of pathogenic microorganisms has been expressed in the last three decades. however, intensive studies on extracts and biologically-active compounds isolated from medicinal plants have also doubled in the last decade. as a result of paucity of knowledge and folkloric claim on the leaves effectiveness in infectious disease treat...

The increasing global public health concern of antimicrobial resistance (AMR) necessitates exploration of natural antimicrobial agents as potential alternatives. This study aims to investigate antimicrobial activities of Saharan actinomycetes, with specific focus on the strain Streptomyces fimbriatus AC31, that holds promising potential as an alternative to combat AMR. In this context, 32 actin...

the purpose of this research was to study the antimicrobial activities of the endophytic fungi from sesbania grandiflora (l.) pers. the endophytic fungi were isolated from branches and leaves of sesbania grandiflora (l.) pers., and sixty nine isolates were obtained. all isolates were screened for antibacterial and antifungal activities. the indicator organisms were 4 bacteria including staphylo...

Objective(s): In this work, pomegranate juice was used as a capping agent for self- assembly to form particles-like Au nanostructures in the presence of AuHCl4.3H2O as aurate source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiments were...
