The removal of Escherichia coli from estuarine water was investigated. The survival of E. coli was dependent on the presence of protozoan predators and not on the presence of lytic bacteria. When indigenous protozoa were removed from estuarine water by filtration, the destruction of coliform populations was negligible. In studies designed to prevent the growth of indigenous bacterial population...

In investigations upon the alteration of the intestinal microflora of chickens by antibiotics added as supplements to rations, an important problem is the enumeration and identification of the coliform group of bacteria in intestinal contents. The importance of the coliform group in the chick's intestinal contents was demonstrated by Rhodes et al. (1954) in studies upon the vitamin-sparing effe...

abstract aims: turbidity in higher than standard levels, indicates failure in the water treatment plant. an electrochemical disinfection process takes place through electricity transition between two or more electrodes. this research aimed to determine the reaction rate of electrochemical process for purification of polluted water. materials & methods: this is a bench scale, experimental study ...

Concentrations of thermotolerant coliform bacteria, presumptive E. coll, and presumptive fecal streptococci were determined from ditches, brooks, and natural ponds in six agricultural areas and 22 uninhabited pristine areas in southern Finland in the summer of 1987. For comparison, the same fecal indicators were enumerated from the effluents of three wastewater t eatment plants. The objective w...

Background and Objectives: Antimicrobial active packaging with metallic nanoparticles is used as antimicrobial agent in the packaging of food. This study considers the coliform retarding ability of antimicrobial packaging in ultra-filtrated (UF) cheese. Materials and Methods: Plastic films based on low-density polyethylene containing organoclay (cloisite 30B) and different percentages of Ag an...

A diurnal study was undertaken in April 2014 to record the bacterial density and some of the physicochemical factors of the river Ganga near Ichapore, West Bengal, India. The pollution indicating bacteria (total coliform, faecal coliform and faecal streptococci) were found in maximum numbers at 14.00 hrs and minimum at 20.00 hrs. All the bacterial populations were abundant and showed diel rhyth...

The waste treatment facilities and final effluents of 11 meat-packing plants in the Province of Alberta were investigated primarily to determine the numbers of indicator bacteria and the presence of Salmonella. This was done to discover the efficiency of the treatment systems presently in operation in reducing bacterial numbers and to establish the need for disinfection and for bacterial standa...

The movement of fecal pathogens from land to surface and ground water are of great interest because of the public health implications. Non-structural best management practices that control the timing, volume, and placement of animal manures are commonly used to limit opportunities for fecal pathogens to enter water bodies. Increased infiltration capacity, water and waste diversions, and vegetat...
