    Bioreactors can be costly to construct since generally the systems are lined and often contain additional components, such as settling ponds and/or aerobic polishing cells. The West Fork system, which contained two parallel bioreactors and an aerobic polishing cell, cost about 700,000 to construct in 1996 (Gusek et al. 1998).

  • Biomining Wikipedia

    Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
