The contamination of soil, sediment, and water by toxic metals is a major problem worldwide, both environmentally, and economically. Microorganisms that are resistant to lead are rare in nature. Lead is toxic to most microorganisms and only a few have developed mechanisms to survive in this toxic environment In this study, bacteria found in soil and water with high concentrations of soluble lead are isolated and characterized. I grew and isolated bacteria that are resistant to the lead found in the solid medium. A gram stain was used to characteristically determine the bacteria that were isolated. Four isolated bacteria were found. Three were found to be cocci in shape, and one was bacillus shaped. After continuation with this research, I hope to identify the four isolated bacteria and to further characterize the bacteria for future studies.
