Available in PDF, EPUB and Kindle. Book excerpt: The single most comprehensive resource for environmental microbiology Environmental microbiology, the study of the roles that microbes play in all planetary environments, is one of the most important areas of scientific research. The Manual of Environmental Microbiology, Fourth Edition, provides comprehensive coverage of this critical and growing field. Thoroughly updated and revised, the Manual is the definitive reference for information on microbes in air, water, and soil and their impact on human health and welfare. Written in accessible, clear prose, the manual covers four broad areas: general methodologies, environmental public health microbiology, microbial ecology, and biodegradation and biotransformation. This wealth of information is divided into 18 sections each containing chapters written by acknowledged topical experts from the international community. Specifically, this new edition of the Manual Contains completely new sections covering microbial risk assessment, quality control, and microbial source tracking Incorporates a summary of the latest methodologies used to study microorganisms in various environments Synthesizes the latest information on the assessment of microbial presence and microbial activity in natural and artificial environments The Manual of Environmental Microbiology is an essential reference for environmental microbiologists, microbial ecologists, and environmental engineers, as well as those interested in human diseases, water and wastewater treatment, and biotechnology.
Download or read book Microbial Source Tracking in the South Dry Sac Watershed written by Emily L. Sturnfield and published by . This book was released on 2011 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Karst watersheds are an important resource that can be easily contaminated. The South Dry Sac Watershed near Springfield, MO presents a unique opportunity to study the combined effects of urban and rural runoff on a karst river system, as the system changes from rural to urban within the span of a few kilometers. Previous studies have indicated that the watershed is impaired by fecal bacteria, but sources of the bacteria were not investigated. This study traced sources of fecal coliform bacteria (bovine, human) in the watershed and related it to land use. Bovine source Bacteroides was prevalent throughout the field area, while human source Bacteroides was present in lower levels. Results indicate higher human fecal loading at sites located near areas using septic waste treatment. Additional water quality parameters helped distinguish water signatures of the urban from the rural areas within the watershed. The two most contaminated sites were tracked to both bovine and human sources, were downstream from known larger-scale cattle operations, and received drainage from unsewered portions of the study area. The range of values obtained and their variation with time provides a good framework for watershed management.

Download or read book Microbial Source Tracking Methods Applications and Case Studies written by Charles Hagedorn and published by Springer Science & Business Media. This book was released on 2011-06-08 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the origin of fecal pollution is essential in assessing potential health risks as well as for determining the actions necessary to remediate the quality of waters contaminated by fecal matter. As a result, microbial source tracking (MST) has emerged as a field that has evolved and diversified rapidly since the first approaches were described only a decade ago. In response to the emergence of MST, there have been three large multi-laboratory method comparison studies (two in the US and one in Europe), plus numerous workshops, book chapters, and review articles dedicated to synthesizing information on the topic. Furthermore, a federal (USEPA) guide document describing the uses and limitations of MST methods was published in 2005, and a book dedicated to MST as an emerging issue in food safety was published in 2007. These documents provide a collective body of literature on MST that is both conflicting and complementary, often repetitious, and difficult to condense and interpret. In addition, it does not reflect the current diversity of MST approaches with different organisms, newer methodologies such as quantitative PCR, and anthropogenic chemicals, nor does it embrace the scope of MST research being conducted around the world. The three editors of the book, all with extensive MST expertise, have developed chapters and invited authors who reflect the rich diversity and truly international scope of MST. The unifying theme throughout the book is the design of more standardized approaches to MST that include performance criteria (regardless of method or organism), plus recommendations for field study design and MST implementation. The editors intend that this book will serve as a valuable reference for all those who are involved with
Download or read book Bacterial Source Tracking in the Sinking Creek Watershed Using Antibiotic Resistance Analysis and Ribotyping written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fecal pollution of surface water is a significant environmental health issue. Indicator organisms are used to monitor microbial water quality, but often their presence does not coincide with the presence of pathogens. Bacterial source tracking is a term describing methods to determine the origin of fecal pollution based on bacterial traits. The objective of this research is to evaluate the use of 2 bacterial source tracking techniques, antibiotic resistance analysis (ARA) and ribotyping, to determine the sources of bacteria isolated from Sinking Creek. Based on the results of this study, ARA and ribotyping are not useful techniques for identifying sources of fecal pollution in Sinking Creek. ARA classification rates were low, and ribotype pattern generation success was 37%. The results of this study bring into question the reliability and reproducibility of these 2 source tracking methods for routine use in small watersheds.

Van Asch and published by . This book was released on 2009 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial source tracking (MST) is a general term given to any process which aims to determine the source of microbial contamination found in an environmental (usually water) sample. These methods include both phenotypic and genotypic strategies. In this study, quantitative PCR was used to evaluate water samples for species specific (cow and human) Bacteroides in the Finley River. The Finley River is susceptible to impacts from both bovine and humans as it flows through farmland and urban areas. Water samples were collected from sites identified in a previous study that had high E. coli levels. Two samples were collected at each site (One sample for enumeration of E. coli and the other to assay for Bacteroides). Sampling was done approximately three times per month for one year. For each sampling event, pH, DO, turbidity, water temperature, flow rate, and rainfall were recorded. The results showed lower than expected cow markers throughout the sampling period; while human markers were much more prevalent than cow markers during the drier (and warmer) months. A correlation was found between human specific Bacteroides markers and E. coli at one site, but not at either of the other two sites. This method affords more informative surveillance data to area health departments so more appropriate remediation strategies can be developed.
