This study set out to examine the cystoseira gibraltarica extract (CG) as an environmentally sustainable corrosion inhibitor for carbon steel in 1.0 M HCl medium. The corrosion inhibiting effect has been studied by conventional methods such as gravimetric (weight loss) and electrochemical (EIS and PDP) methods. All the methods used in this study confirm that cystoseira gibraltarica extract has ...

Background and objectives: Resistance towards reveling antibiotics has captured great interest in evaluating the antimicrobial properties of the natural plants. Taraxacum mongolicum is widely used as a folklore medicinal plant for its diuretic, antirheumatic and anti-inflammatory properties. Though there are some reports on antimicrobial properties of Taraxacum mongolicum, stu...

background: shigella spp. are gram negative bacteria, which are of global public health importance. the growing of multidrug-resistant shigella isolates are a major problemaround the world. methods: overall, 50 isolates of shigella spp. from children diarrheic stools were studied. the isolates were identified and confirmed using biochemical, serological and molecular methods (ipah, wbgz and rfc...

Six clinical isolates of Staphylococcus aureus were compared for their relative susceptibilities to the killing effects of oxacillin. Three of the strains had minimum bactericidal concentrations which were >10 times the minimum bacteriostatic concentration for this antibiotic and were designated tolerant (Tol(+)). The other strains had minimum bactericidal concentrations which were comparable t...

Recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of Bacterial resistance to antimicrobial agents in chemical.The aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on Escherichia coli. Gold nanoparticles are chemically synthesized. Standard strain of E. coli was cultured in a nutrient broth. Minimum ...
