| Abstract |
The primary objective of this research project was to increase the sensitivity of the ARCAT method to detect one coliphage per 100 ml of water sample. Several concentration techniques were evaluated and three methods selected for in-depth study. Two of the methods selected for in-depth study were filter concentration techniques. The third method involved amplification of coliphages by addition of nutrients and a host culture followed by incubation to allow a lytic burst cycle to occur. Of these techniques, the Zeta Plus 60S filtration technique proved to be the optimum method. Coliphage adsorption with this filter range from 80-100%. Coliphage recoveries from the filters were > or = 90%. With this concentration method, test results can be obtained within 6 1/2 hours with a sensitivity of 1 coliphage per 100 ml. |
