Oligodynamic Effects of Copper against Water-borne Pathogens
J. Environ. Nanotechnol., Volume 8, No 4 (2019) pp. 08-09
Abstract
In this work, investigations have been carried out on the oligodynamic properties of copper against water-borne pathogens. The microorganisms were isolated from the water samples from Kollam District, Kerala, India, by serial dilution of the water samples and then plated them onto a melted nutrient agar plate. After incubation, colonies appeared on selective agar plates, which were simple-stained and gram-stained. Hydrolysis by an enzyme (starch, lipid and casein), fermentation of carbohydrates with different sugars (sucrose, glucose and lactose), nitrate reduction, triple sugar ion test, IMVIC test and H2S test were conducted and reported.
