Application of a tetrazolium dye as an indicator of viability in anaerobic bacteria
Journal of Microbiological Methods, 1999The use of the redox dye 5-cyano-2,3,-ditolyl tetrazolium chloride (CTC) for evaluating the metabolic activity of aerobic bacteria has gained wide application in recent years. In this study, we examined the utility of CTC in capturing the metabolic activity of anaerobic bacteria.

Bioluminescent Bacteria as Indicators of Chemical Contamination of Coastal Waters
Journal of Environmental Quality, 2005ABSTRACTThe ratio of bioluminescent to total bacteria (bioluminescent ratio, BLR) as an indicator of a variety of types of anthropogenic contamination of estuarine ecosystems was evaluated through a series of laboratory and field studies. Laboratory studies indicated that the BLR of natural bacterioplankton communities was proportionally reduced in the

Prevalence and Persistence of Antimicrobial Resistance in Broiler Indicator Bacteria
Microbial Drug Resistance, 2010This study explored the prevalence and persistence of acquired antimicrobial resistance in Escherichia coli and Enterococcus faecium from healthy broilers. In 32 broiler farms, cloacal samples were taken during two production rounds, with one production round in between.

Campylobacters, Salmonellas, and Indicator Bacteria in the Lune Estuary
1996Estuaries are increasingly being used for recreational purposes. The Lune estuary at Lancaster, for example, is a centre for water skiing and jet skiing. Such sports can only be done at high-water, which unfortunately coincides with the discharge of sewage effluent into the estuary from Lancaster’s effluent treatment works (ETW).

Variations of Indicator Bacteria in a Large Urban Watershed
Transactions of the ASABE, 2011The contamination of water resources by nonpoint-source fecal pollution is a major concern to human health and water quality throughout the world. The Santa Ana River (SAR) in southern California is an impaired stream with historically high fecal coliform counts.

Taxonomy, Phylogeny, and Physiology of Fecal Indicator Bacteria
2014In studies of environmental quality, there are several different groups of bacteria frequently used as fecal indicators. The most widely applied approach is to use the group represented by the family Enterobacteriaceae (coliforms and fecal coliforms).

Animals and Humans as Sources of Fecal Indicator Bacteria
2014This chapter talks about the distribution of the major indicator bacteria, Escherichia coli, Enterococcus spp., and a variety of anaerobes (including Clostridium perfringens, Bifidobacteria spp., and members of the Bacteroidales) in humans, in domesticated animals and birds, and in undomesticated animal hosts.

Effect of high-power microwave on indicator bacteria for sterilization
IEEE Transactions on Biomedical Engineering, 1996According to the superiority sterilization, a specially-designed microwave disinfector using high-power microwave energy was made. A series of sterilizing experiments have been made to determine the effect of microwave energy on several typical indicator bacteria such as Bacillus subtilis var.
