Prospect Research on the Diversity of Extracellular Mineralization Process Induced by Mineralizing Microorganisms and Its Use as a Treatment for Soil Pollutants

Microbial-induced mineralization is a process in which metal ions the environment are processed by microorganisms, forming deposits of crystals with cementing and void-filling functions. Cementing can fix ions, reduce permeability, improve soil strength, play positive role remediation pollution control. This paper first introduces principle microbial-induced analyzes its mechanism action treatment organic inorganic pollutants. Then, different types mineralized bacteria (fungal metabolism involving acid complexation metabolic urease catalysis, sulfur oxidation sulfur-oxidizing bacteria, dissimilatory sulfate reduction sulfate-reducing ammonification ammoniating reverse digestion denitrifying catalysis urease-producing acetic fermentation methanogenic H2/CO2 reduction) elaborated, influencing factors pollutants technology practical application analyzed, current status for summarized. Finally, future prospects pollutant outlined to promote research into
