Validity of fecal coliforms, total coliforms, and fecal streptococci as indicators of viruses in chlorinated primary sewage effluents [PDF]
Applied and Environmental Microbiology, 1978 Quantities of combined chlorine that usually destroyed more than 99.999% of the indigenous fecal coliforms, total coliforms, and fecal streptococci in primary sewage effluents destroyed only 85 to 99% of the indigenous viruses present. Viruses were recovered from five of eight chlorinated primary effluents from which fecal coliforms were not recovered ...

Molecular Method for Detection of Total Coliforms in Drinking Water Samples [PDF]
Applied and Environmental Microbiology, 2014 ABSTRACT This work demonstrates the ability of a bacterial concentration and recovery procedure combined with three different PCR assays targeting the lacZ , wecG , and 16S rRNA genes, respectively, to detect the presence of total coliforms in 100-ml samples of potable water ...

Comparison of Verification Procedures for the Membrane Filter Total Coliform Technique [PDF]
Applied and Environmental Microbiology, 1983 Verification of membrane filter total coliform colonies from drinking water was increased 87% by testing for the presence of β-galactosidase and cytochrome oxidase, compared with verification by determination of gas production in lauryl tryptose broth.

Evaluation of the Autoanalysis Colilert test for detection and enumeration of total coliforms [PDF]
Applied and Environmental Microbiology, 1989 The Autoanalysis Colilert (AC) test was compared with the membrane filter (MF), 10-tube multiple-tube fermentation (MTF) technique, and the presence-absence test as described in Standard Methods for the Examination of Water and Wastewater for the detection and enumeration of total coliforms in water.

Statistics and Probability Distribution of Total Coliforms in Wastewater
Journal of The Korean Society of Agricultural Engineers, 2013 Probability distribution of microbes in wastewater is a crucial factor to be determined for microbial risk assessment associated with its reuse. The objective of this study was to investigate probability distribution of an indicator microorganism in wastewater.
