  • Multiplex PCR for detection of water-borne bacteria

    Microbial water-borne diseases still affect developing countries and are major water quality concerns throughout the world. Routine culture-based methods of identifying bacterial pathogens in water sources are laborious and time-consuming. Recently, the use of molecular techniques such as the polymerase chain reaction (PCR) has provided rapid and highly promising detection methods. In this ...

  • Nitrate removal from water by immobilized bacteria

    Nitrate may reach surface and ground waters as a consequence of agricultural activity and discharge of domestic and industrial waste. Among the various methods used for nitrate removal, denitrification, a process in which nitrate is biologically reduced to elemental nitrogen, is relatively reliable and inexpensive as compared to other physical and chemical nitrate removal processes. ...

  • Bacteroides bacteria and their bacteriophages

    There are many sources that can contribute to fecal contamination in water bodies such as domestic wastewaters, wastewater treatment plants, husbandry and farms. Coliform bacteria are a group of bacteria that inhabit in the digestive tracts of human and warm-blooded animals. It can be found in human and animal feces. Therefore, the presence of coliform bacteria can indicate fecal contamination, ...

  • An Evaluation of the Effectiveness of the Gunderboom® in Protecting Waters from Bacteria

    Beaches located in the narrow inlet of Long Island Sound frequently contain high concentrations of bacteria. A Gunderboom® BPS™ (Beach Protection System) filter was installed in Harbor Island Park of Mamaroneck Harbor, New York, in 2002 to reduce bacterial levels in the water. Water and sediment collected inside and outside the Gunderboom® and other areas within Mamaroneck Harbor (Shore Acres ...

  • Proof That Bacteria Degrade Oil

    There has been a lot of publicity and ‘noise’ around the ability of bacteria to degrade oil, especially following BP’s Gulf of Mexico incident.  However little has been shown to prove that biological remediation is an effective means of treating oil contamination. Over many years CBIO have worked to develop a range of a microbial products that have proven to be able to ...

  • Bacteria devours gasoline plume

    The new environmental technology essentially flushes contamination out of the soil. NORTHAMPTON - With hungry bacteria and reusable carbon filters, an engineering company is slowly but surely removing a massive plume of gasoline from beneath a busy section of Pleasant Street. Traffic and business activity haven't had to skip a beat as Penney Engineering, of Mansfield, cleans up the ...

  • Significance of indicator bacteria in a regionalised wastewater treatment plant and receiving waters

    A regional wastewater treatment plant was found to be discharging high concentrations of fecal coliform bacteria in excess of acceptable surface water criteria. An investigation of the sources of those bacteria showed their origins to have been environmental, primarily from a pulp and paper mill. False positive and false negative fecal coliforms were also found and enumerated. These bacteria were ...

  • Rapid detection of pathogenic bacteria in surface water by PCR with universal primer

    A rapid PCR method was developed by utilising a pair of universal primers which targeted four bacteria strains, namely Shigella dysenteriae, Vibrio cholerae, Salmonella typhimurium and Escherichia coli. The bacteria from several water bodies in the urban area of Xi'an City were detected by PCR, and the comparison was made with the conventional method. As a result, the detection limit of the DNA ...

  • Survival of human pathogenic bacteria in different types of natural mineral water

    The aim of this study was to determine the survival of human pathogens (Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa) in five natural mineral waters (NMWs) with different properties and mineralization levels. Five NMWs from four Spanish spas with different dry residue at 110 °C were used: A = 76,935 mg/L; B = 1,827 mg/L; C = ...

  • Aggregation and biofilm formation of bacteria isolated from domestic drinking water

    The objective of this study was to investigate the autoaggregation, coaggregation and biofilm formation of four bacteria namely Sphingobium, Xenophilus, Methylobacterium and Rhodococcus isolated from drinking water. Auto and coaggregation studies were performed by both qualitative (DAPI staining) and semi-quantitative (visual coaggregation) ...

  • Quantification and identification of aerobic bacteria in holy water samples from a German environment

    Despite its frequent use in many religious institutions, the microbiological quality of holy water is clearly underinvestigated. We analyzed the microbial load of 54 holy water samples, repeatedly taken in five Roman Catholic churches in the greater area of Villingen-Schwenningen, Germany, by means of aerobic colony counting and Matrix-Assisted Laser Desorption/Ionization (MALDI) Biotyping of ...

  • Potentially pathogenic bacteria isolated from different tropical waters in Sri Lanka

    This study investigated the bacteriological contamination of different water sources in Sri Lanka. Source waters (n = 74) including bottled water, well water and surface water were assessed for enumerating total coliforms and faecal coliforms using the membrane filtration method. The results showed that 18.5 and 14.8% of bottled water samples were contaminated with total ...

  • Battling Iron Bacteria Contamination in Mining

    Published in the May issue of International Mining, this article focuses on the problem of iron bacteria contamination in the water supply for the Tiwest Mine at Cooljarloo, Australia. Mines rely heavily on groundwater sources and the quality and flow of that water have both operational and regulatory implications. The problem of mineral and bacterial contamination in groundwater sources can ...

  • Pathogenic features of heterotrophic plate count bacteria from drinking-water boreholes

    Evidence suggests that heterotrophic plate count (HPC) bacteria may be hazardous to humans with weakened health. We investigated the pathogenic potential of HPC bacteria from untreated borehole water, consumed by humans, for: their haemolytic properties, the production of extracellular enzymes such as DNase, proteinase, lipase, lecithinase, hyaluronidase and chondroitinase, the effect ...

  • Disease-causing bacteria made more resilient by standard water disinfection practices

    Halogenated nitrogenous disinfection by-products (N-DBPs) in water increase bacterial resistance to antibiotics, new research shows. The study found that a strain of bacteria which can cause disease in humans, Pseudomonas aeruginosa, increased its resistance to a range of different antibiotics by an average of 5.5 times after the bacteria were exposed to chemicals which form as by-products of ...

  • Faecal indicator bacteria in river biofilms

    Biofilms in surface waters primarily consist of allochthonous microorganisms. Under conditions of pollution faecally derived bacteria may interact with these biofilms. Total coliform bacteria, Escherichia coli and intestinal enterococci are used to monitor source water quality, indicating faecal pollution and the possible presence of enteric pathogens. In the present study the occurrence of ...
