Phaseolus vulgaris seeds were surface sterilized using ethanol 90%, soaked in sterile distilled water for 60min, then soaked in copper and silver nanoparticles at different concentrations (25, 50 or 100mg/l) for 15 and 30min. The effect of nanoparticles on the plant physiological characteristics in vivo was studied.
One of the major environmental problems is the pollution of water by heavy metals. Using the biological treatment is an effective way to reduce heavy concentration because it's environmental friendly,
Actinomycetes produce a wide range of secondary metabolites and more than 70% of the naturally derived antibiotics that are currently in clinical use are derived from soil Actinomycetes and increasing of the pathogens resistant against antimicrobial agents becomes a health problems, so the current study was aimed to isolation of local Streptomyces spp. that is capable of producing secondary metabolite and investigate their biological antimicrobial and anticancer activities.
