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 sanitary evaluation of equipment and hands is fundamental to investigate the presence pathogens in dairy industry. Then, this study aims evaluate sanitization equipment, workers’ hands, raw pasteurized milk goat dairies Cariri region, state Paraíba. Collected 32 samples four represented by letters A, B, C, D. followings contents were analyzed: mesophiles, total thermotolerant coliforms, Esc...

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...

better understanding and recognizing the amount of cultural development in iranian provinces and comparing them, causes a particular attention and helps to recognize their weaknesses, strengths, potentialities and deficiencies. the purpose of this paper is to analyze cultural development indicators in iran. the writers of this article present an applied research and use a comparative method. us...

Concern has greatly increased about the potential for contamination of water, food, and air by pathogens present in manure. We evaluated pathogen reduction in liquid swine manure in a multi-stage treatment system where first the solids and liquid are separated with polymer, followed by biological nitrogen (N) removal using nitrification and denitrification, and then phosphorus (P) extraction th...

Commercial poultry abattoirs were evaluated to determine the efficacy of the multi-hurdle antimicrobial strategy employed to reduce the microbial load present on incoming broilers from the farm. As next generation sequencing (NGS) has been recently employed to characterize the poultry production system, this study utilized 16S High throughput sequencing (HTS) and quantitative plating data to pr...
