Advances in Manganese Pollution and Its Bioremediation (original) (raw)

Soil biology, 2015

Abstract

The requirement for manganese (Mn) has augmented extensively owing to the intense production of steel and the mounting paucity of natural deposits. The widespread mining, mineral processing, and further human activities have faced a severe consequence in the generation of massive quantity of manganese mining waste residues. The inappropriate supervision and unprocessed liberation of these wastes have resulted in the spread of Mn to the contiguous atmosphere, soil and groundwater pollution, and loads of severe ecological tribulations. Chronic and acute exposure of this metal pollutant leads to lethal consequences and is clinically categorized by the multiple symptoms of neurotoxicity including cognitive and psychiatric symptoms, Parkinson’s disease, manganism, motor system dysfunction, and other neurodegenerative diseases. The advancement of bioremediation technology focuses on accomplishing successful removal of these metal pollutants by increasing the effectiveness of microbes related to metal-solubilizing activities. This chapter describes a complete advance in the research on manganese environmental pollution, manganese compound-induced toxicity, and recent approaches for the microbial remediation of manganese pollutants.
