TI  - Microbially Induced Calcium Carbonate Precipitation as a Bioremediation Technique 
      for Mining Waste.

AB  - Mining waste represents a global issue due to its potential of generating acidic 
      or alkaline leachate with high concentrations of metals and metalloids 
      (metal(loid)s). Microbial-induced calcium carbonate precipitation (MICP) is an 
      engineering tool used for remediation. MICP, induced via biological activity, 
      aims to precipitate calcium carbonate (CaCO(3)) or co-precipitate other metal 
      carbonates (MCO(3)). MICP is a bio-geochemical remediation method that aims to 
      immobilize or remove metal(loid)s via enzyme, redox, or photosynthetic metabolic 
      pathways. Contaminants are removed directly through immobilization as mineral 
      precipitates (CaCO(3) or MCO(3)), or indirectly (via sorption, complexes, or 
      inclusion into the crystal structure). Further, CaCO(3) precipitates deposited on 
      the surface or within the pore spaces of a solid matrix create a clogging effect 
      to reduce contaminant leachate. Experimental research on MICP has shown its 
      promise as a bioremediation technique for mining waste. Additional research is 
      required to evaluate the long-term feasibility and potential by-products of 
      MICP-treated/stabilized waste.
