viable cell concentration and luminescence activity of p. stutzeri p16 luxab4 was measured byplate counting and luminometery in sterile and non-sterile soil adjusted to matric potential of -1500, -750 and-30 kpa. results showed that matric potential had a significant effect on survival and activity of p. stutzerip16 luxab4 in soil. p. stutzeri p16 luxab4 could survive better in hutner’s minimal...
antibiotic resistance is a public concern, worldwide. the purpose of this study was to survey the antibiotic susceptibility pattern in the microorganisms isolated from the clinical samples in shahid faghihi hospital of shiraz, iran. in this study, the microorganisms were isolated from the blood, bone marrow, pleural fluid, csf and vaginal discharge. antibiotic susceptibility test was performed ...
the microfiltration 0.2 µm cellulose acetate (ca) membrane was modified by embedding antibacterial silver nano-particles in the membrane pores. this novel technique was developed to enhance the capability of the microfiltration membrane for removing microorganism including bacteria. the prepared membrane was characterized using scanning electron microscopy (sem), energy-dispersive x-ray spectro...
The aim of the present study was to obtain insights into the relationship between the chemical (salt content and pH) and physico-mechanical (humidity and compressive strength) properties of mineral-based materials from historic buildings with salt efflorescence and the growth and biodiversity of halophilic microorganisms. Samples were mainly characterized by pH 6.5-8.5 and a moisture content of...
