  • 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 ...

  • 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, ...

  • 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. ...

  • 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 ...

  • A review of technologies for rapid detection of bacteria in recreational waters

    Untitled Document ABSTRACT Monitoring of recreational beaches for fecal indicator bacteria is currently performed using culturebased technology that can ...

  • 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 ...

  • Estimation of dead or live bacteria using online Bacteria Activity monitoring - Case Study

    The BACTcontrol, a microLAN instrument, measures on-line bacterial enzyme activity in food and aquatic samples. Besides ß-DGlucuronidase, ß-Galactosidase and ß-Glucosidase to measure E.coli, Coliform and Enterococci activity respectively also alkaline phosphatase (ALP) activity is measured to determine Total Activity. The BACTcontrol TA test measures the metabolism activity of ...

  • 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 ...

  • 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 ...

  • Kinetic modelling of the photocatalytic inactivation of bacteria

    This work analyzes the kinetic modelling of the photocatalytic inactivation of E. coli in water using different types of kinetic models; from an empirical equation to an intrinsic kinetic model including explicit radiation absorption effects. Simple empirical equations lead to lower fitting errors, but require a total of 12 parameters to reproduce the results of four inactivation curves when 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 = ...

  • The Missing Link in Bacteria TMDLs: Natural Growth

    INTRODUCTIONFecal indicator bacteria (FIB), including total coliform, fecal coliform (or E. coli), and Enterococcus, have long been used to indicate the contamination of fecal matters in beaches, streams, and lakes (USEPA, 1986, 2002). When the bacterial concentration in a waterbody exceeds the FIB water quality criteria, the waterbody may be identified on the Clean Water Act Section 303(d) list ...

  • Overcoming iron bacteria problems: An Australian perspective

    Iron bacteria are becoming an increasing problem in groundwater bores and are estimated to affect about 40% of the world’s water bores with anecdotal evidence indicating that this number is steadily increasing. Iron bacteria derive energy during their metabolism through oxidising soluble ferrous iron, present in the groundwater, to its insoluble ferric form. The resultant biofilm is ...
