Bacteria from water and sediment of an oil-polluted harbor were examined for ability to degrade petroleum. Water samples contained a greater variety of bacterial species capable of degrading petroleum than sediment. Cultures from both water and sediment contained Pseudomonas and Acinetobacter spp. Bacteria present in the water samples produced significantly greater degradation of 2-,3-,4-, and ...

This study evaluated the bacterial distribution and the survivability of bacteria associated with different particle size ranges in the sump water and sediments within two structural Best Management Practices (BMPs), called Vortechs, installed at two different sites in Providence, Rhode Island. Ten rain storms were sampled in year 2004. Five pathogenic indicator bacteria, E. coli, enterococci, ...

The effect of acidic, electrolyzed oxidizing (EO) water and chlorinated water on the spoilage microflora of processed broiler carcasses was examined. Carcasses were sprayed for 5 s at 80 psi with tap, chlorinated, or EO water in an inside-outside bird washer. Treated carcasses were then stored at 4 degrees C for 0, 3, 7, or 14 d, and the microbial flora of the carcasses was sampled using the wh...

Background and Objective: Food-borne diseases are among the most important public health problems. Among them, Salmonella is one of the most important food pathogens. Different Salmonella serotypes enter body through food and causes food infections in consumers. One of the most important evaluation criteria for health is to determine the microbial load of food. Materials and Methods: In this s...

BACKGROUND One of the major health causing problems is contamination of drinking water sources with human pathogenic bacteria. Enteric bacteria such as Shigella, Salmonella and Escherichia coli are most enteric bacteria causing serious health problems. Occurrence of such bacteria infection, which may resist antibiotics, increases the seriousness of problem. OBJECTIVES The aim of this study wa...

Background & Aims of the Study: The heterotrophic bacteria are widely used as a water microbial pollution index for drinking water. The aim of this study was to investigate the effect of metallic nanoparticles such as Zero Valent Iron (ZVI), Titanium dioxide (TiO2) and Zinc oxide (ZnO) on Heterotrophic Bacter...

Controlling the microbiological quality of water is important for its uses. Microbiological requirements of drinking water ensure the absence of coliforms, but may indicate the potential presence of other potentially pathogenic microorganisms and viruses of fecal origin. A total of 36 water samples, representing the drinking water of the whole city of Aradan, Semnan, Iran, were randomly collect...
