Research on biological solutions for sustainable environmental health has grown significantly over the years, highlighting urgent need innovative and effective remediation strategies. Bioremediation, an ecologically significant practice, uses agents to address despoiled habitats by harnessing metabolic potential of microorganisms or cells degrade, remove, dispose contaminants from soil, water, air. Bioremediation pathways are part general life processes, like energy production, do not result in breaking down one pollutant into a harmful substance. A broad spectrum pollutants can be bioremediated through specific selection such as bacteria, microalgae, aquatic pulmonate, fungi, plants. The ecological any ecosystem human emphasized, chemical spills components influence management hydraulics results due intricate food chain. stands development low-cost methodology removing heavily affected parts, several cases their enzymes processes used removal industrially produced hazardous substances. following sections dedicated detailed understanding exploration biodegradation useful pollutants, well reduction hazards. developments methodologies parts.
