Introduction
Microbial bioremediation is a promising and environmentally friendly approach for the removal or reduction of heavy metals from contaminated sites. Heavy metals, such as lead, cadmium, mercury, and arsenic, are toxic pollutants that can accumulate in the environment and pose serious risks to human health and ecosystem stability. Traditional methods of heavy metal remediation, such as chemical precipitation and physical adsorption, can be expensive, energy-intensive, and may generate toxic byproducts. In contrast, microbial bioremediation harnesses the natural abilities of microorganisms to transform, immobilize, or extract heavy metals from contaminated sites.
This thesis explores the potential of microbial bioremediation for the removal of heavy metals from contaminated environments. The study aims to investigate the efficacy of different microbial strains in remediation processes, as well as the factors influencing their performance. By understanding the mechanisms involved in microbial bioremediation, this research seeks to provide insights into optimizing bioremediation strategies for heavy metal-contaminated sites.
