Groundwater Contamination by Heavy Metals in Water Resources of Shiraz Area
Lack of sewage collection systems, percolation of surface waters, and seepage of wells have raised the groundwater table in Shiraz area in the south of Iran. The growing population generates environmental pollution resulting in the degradation of the quality of surface and groundwaters used for agriculture. Inorganic and organic pollutants have been traced in Shiraz water resources. Heavy metal...
متن کاملAntimicrobial Effect of Lactic Acid Bacteria against Common Pathogenic Bacteria
Abstract Background and Objective: Probiotics are living microorganisms that have beneficial effects on the health of digestive system. The aim of this study was to evaluate the antimicrobial ability of acidic and neutral supernatants (culture supernatant) of lactic acid bacteria against common bacterial pathogens. Meth...
متن کاملEnteropathogenic Bacteria Contamination of Unchlorinated Drinking Water in Korea, 2010
OBJECTIVES The purpose of this study was to assess the microbiological quality of unchlorinated drinking water in Korea, 2010. One hundred and eighty unchlorinated drinking water samples were collected from various sites in Seoul and Gyeonggi province. METHODS To investigate bacterial presence, the pour plate method was used with cultures grown on selective media for total bacteria, total col...
متن کاملIsolation and Identification of Pathogenic Bacteria from Drinking Water
Drinking water microbiological quality was primarily determined by enumeration of “indicator organisms”, whose presence indicates faecal contamination. The presence of the indicators is often a key in assessing potential public health risks due to bacterial pathogens and is used in drinking water quality regulations and guidelines in many countries. The enumeration of fecal coliform specificall...
متن کاملEvaluating the growth potential of pathogenic bacteria in water.
The degree to which a water sample can potentially support the growth of human pathogens was evaluated. For this purpose, a pathogen growth potential (PGP) bioassay was developed based on the principles of conventional assimilable organic carbon (AOC) determination, but using pure cultures of selected pathogenic bacteria (Escherichia coli O157, Vibrio cholerae, or Pseudomonas aeruginosa) as the...
