FECAL COLIFORM RELEASE FROM CATTLE FECAL DEPOSITS1
JAWRA Journal of the American Water Resources Association, 1984ABSTRACT: Cowpies molded to a standard configuration and size were subjected to simulated rainfall, and the fecal coliform counts were determined using the most probable number (MPN) method of enumeration. The standard cowpie deposits were exposed to simulated rainfall once at ages 2 through 100 days.

Coliform-Fecal Coliform Bacterial in Tidal Waters
Journal of the Sanitary Engineering Division, 1968The fecal coliform-coliform relationship has been examined for several estuaries on Long Island to evaluate proposed fecal coliform standards for shellfish growing waters. The level of fecal coliforms to coliforms was found to vary with source of pollution, level of treatment provided, characteristics of the receiving waters, and precipitation on the ...

Extended Acid Digestion for Inactivation of Fecal Coliforms
Water Environment Research, 2006The objective of this research was to establish a correlation between inactivation of fecal coliforms caused by organic acids in their un‐ionized form in batch acid digesters and semicontinuously fed acid digesters at both mesophilic (38°C) and low‐mesophilic (24°C) temperatures. Batch acid digesters achieved a U.S.

Regrowth of Fecal Coliforms in Class A Biosolids
Water Environment Research, 2006Eight types of Class A biosolids were tested for fecal coliform (FC) reactivation and/or regrowth at 20, 35, and 50°C for 21 days. Growth of FC did not occur at 20 or 50°C, but it was observed in two samples incubated at 35°C after a lag period of 48 hours. In undigested biosolids, final FC concentration exceeded 10 4 MPN/g, whereas in thermophilically

Agar Medium for Enumeration of Fecal Coliforms
Journal of Food Science, 1992ABSTRACT Spread‐inoculated plates of fecal‐coliform agar (FCA) were pre‐incubated 2 hr at 35°C, and then transferred to 44.5°C for 22 hr. Fecal coliforms on FCA produce acids and CO 2 , which react with bromocresol purple and calcium lactate to form yellow to yellow‐green ...

Association of Fecal Coliforms With Soil Aggregates
Soil Science, 2009Manure-home microorganisms and organic particles can move in soils in large interconnected pores or in long macroporcs. These pathways in structured soils are located between soil aggregates or peds. Therefore, interaction with soil aggregates ma y substantially affect the ability of macropores to serve as bacterial conduits.

Fecal coliform densities in a Western watershed
Water, Air, and Soil Pollution, 1982This paper describes the areal distribution of fecal coliform densities within the stream system of the South Platte River basin in Colorado. Low densities, e.g., 0 to 99 fecal coliforms per 100 ml, were found in mountain streams, while higher densities, e.g., 10000 to 100000 and above were found in plains streams. About 49 % of the plains stations and

REGROWTH OF FECAL COLIFORMS IN CLASS A BIOSOLIDS
Proceedings of the Water Environment Federation, 2004Eight types of Class A biosolids were tested for fecal coliform (FC) reactivation and/or regrowth at 20, 35, and 50?C for 21 days. Growth of FC did not occur at 20 or 50?C, but it was observed in two samples incubated at 35?C after a lag period of 48 hours.

Significance of fecal coliform and fecal streptococcus in water pollution monitoring
Acta Academiae Medicinae Wuhan, 1982The experimental results showed that the fecal coliform (FC) to fecal streptococcus (FS) ratio (FC/FS) in the human feces and in warm-blooded animal feces were rather different. FC/FS ratio in the human feces was greater than 7.0, and in warm-blooded animal feces was less than 1.0.
