Metal(loid) Bioremediation: Strategies Employed by Microbial Polymers

Ayansina Segun Ayangbenro / Olubukola Oluranti Babalola

Environmental pollution arising from metal(loid)s is a result of industrialization, and has led to serious health issues. Conventional methods of metal(loid) removal often results in generation of secondary waste which is toxic to the environment. Bioremediation in combination with physicochemical techniques offer an excellent and effective means of removal. The use of secondary metabolites and extracellular polymers produced by microorganisms is an effective procedure employed in metal(loid) sequestration and reduction in toxicity of contaminated environments. These biopolymers have different chemical structures and have shown varied selectivity to different metal(loid)s. This review discusses various microbial polymers, their mechanism of metal(loid) removal and their potential application in remediation of contaminated environment.
