ABSTRACT:   Bronze containers of different sizes with different composition of copper have beneficial effects in decontaminating different bacteria from water at different durations. Experiments revealed that Gram- negative bacteria in water were no longer detected after storage in bronze containers within 24 hours. The experiment was conducted by using bronze containers of different capacities (50 ml-500 ml). Sterilized distilled water was seeded with 105-107 organisms per ml each of Escherichia coli (ATCC 25922), Salmonella typhi,Proteus morganii,Vibrio choleraeStaphylococcus aureus and Bacillus subtilis from overnight broth cultures. Bacteria count was done hourly by using respective selective media plates such as MacConkey agar for E.coli and S .typhi and TCBS agar for V. cholerae and nutrient agar for S. aureus and B. subtilis by the streak method. The plates were incubated at 37ºC overnight and colony count was calculated. It was observed that all Gram-negative bacteria tested were not recovered after 4 hours of storage. The growth of bacteria depends on the type of bronze used.
