Percentage of gelatinolytic bacteria among heterotrophic bacteria as indicator of water quality

Folia Microbiologica, 2004
The relationship between the physiological group of gelatinolytic bacteria and the abundance of heterotrophic bacteria in freshwater ecosystems was described, based on analysis of 1082 different freshwater samples collected in Croatia. Percentages of gelatinolytic bacteria among the population of heterotrophic bacteria showed a significant negative ...

Enumeration of Indicator Bacteria Exposed to Chlorine

1983
Stress resulting from a variety of chemical and physical environments has been recognized in indicator bacteria. A review by Busta (1976) summarizes the extensive work that has been carried out to describe indicator microorganisms sublethally impaired due to a variety of causes associated with foods.

Marine bacteria as indicators of water quality

Chemosphere, 1994
Abstract Preliminary results on the concentration of aerobic, heterotrophic marine bacteria, and on its luminescent fraction in plated filters of coastal water samples, both under “clean” and polluted conditions, are reported. The feasibility of the application of such an approach in characterizing the integrity of marine environments, with the ...

Indicator bacteria in freshwater and marine molluscs

Hydrobiologia, 1984
The freshwater mussel Anodonta cygnea and four marine shellfish (mussels, Mytilus edulis; cockles, Cerastoderma edule; clams, Mya arenaria; Scrobicularia plana) from a total of six sites were surveyed for Escherichia coli, Clostridium perfringens, faecal streptococci, 25 and 37 °C coliforms, 25 °C and 37 °C total viable numbers and fluorescent ...

Anaerobic bacteria as indicators of faecal pollution

Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1980
SynopsisIn several well-authenticated instances intestinal pathogens, includingSalmonellaspecies, have been isolated from water in the absence of bacteria, such asEscherichia coli,commonly used to detect faecal pollution. The present study examines certain anaerobic, non-sporing commensals of the intestinal tract as alternative ‘indicator’ bacteria ...

Current Concepts of Indicator Bacteria

1977
Pathogenic bacteria excreted in human feces are found in low counts in wastewater and are known to be more sensitive to environmental conditions than Escherichia coli. The latter, excreted both by humans and warm-blooded animals, are used as an indicator of fecal wastes which may contain the pathogen, but the validity of this practice is often ...

Bacteriophages and indicator bacteria in human and animal faeces

Journal of Applied Bacteriology, 1986
In an attempt to explain the presence of F‐specific (RNA) bacteriophages in waste‐water, faecal material from humans and a variety of animals was examined. The phages were detected in appreciable numbers only in faeces from pigs, broiler chickens, sheep and calves but not from dogs, cows, horses and humans. Parallel examinations for somatic coliphages,

Addressing uncertainty in fecal indicator bacteria dark inactivation rates

Water Research, 2011
Assessing the potential threat of fecal contamination in surface water often depends on model forecasts which assume that fecal indicator bacteria (FIB, a proxy for the concentration of pathogens found in fecal contamination from warm-blooded animals) are lost or removed from the water column at a certain rate (often referred to as an "inactivation ...

Comparing Wastewater Chemicals, Indicator Bacteria Concentrations, and Bacterial Pathogen Genes as Fecal Pollution Indicators

Journal of Environmental Quality, 2009
The objective of this study was to compare fecal indicator bacteria (FIB) (fecal coliforms, Escherichia coli [EC], and enterococci [ENT]) concentrations with a wide array of typical organic wastewater chemicals and selected bacterial genes as indicators of fecal pollution in water samples collected at or near 18 surface water drinking water intakes ...
