background and aims: in iran herbal water and dried herb are as traditional medicinal and are consumed widely. therefore, microbial evaluation of these products in term of public health is important. the aim of the present study was to study the contamination of some dried medical plants and distillates in the groceries of shahrekord city. methods: in this descriptive study, 35 samples of herba...

silver nanoparticles with size of 6- 57nm were synthesized by bioreduction method from anisochilus carnosus aqueous and ethanolic extract. biosynthesized nanoparticles showed maximum antimicrobial activity against k. pneumonia (13±1.67mm), e.coli (13±1.97mm) and b. subtilis (13±1.07mm) followed by p. aeruginosa and minimum against s. aureus. the quantitative formation, characteristics and impur...

AIMS We investigated the effectiveness of ozone (aqueous and gaseous) treatment as an alternative sanitizing technology to common conventional disinfectants in reducing the microbial contamination of both water and air. METHODS Ozone was added for 20 minutes to a well-defined volume of water and air by the system named "Ozonomatic®". The effectiveness of ozonation was determined by counting C...

background: date is one of the foodstuff s that are produced in tropical areas and used worldwide. conventionally, methyl bromide and phosphine are used for date disinfection. the toxic side effects of these usual disinfectants have led food scientists to consider safer agents such as ozone for disinfection, because food safety is a top priority. the present study was performed to investigate t...
