Q.What is bioremediation? give some examples of bioremediation.

Step 1. Define bioremediation. The chapter defines bioremediation as 'the use of microorganisms or plants to clean up environmental pollution', applied to wastewater, industrial waste and solid waste, and specifically to removing oil, petrochemical residues, pesticides or heavy metals from soil or groundwater - often cheaper and more sustainable than physical/chemical remediation.

Step 2. Give plant/fungus-based examples. Phytoremediation uses plants to remediate environmental pollutants; mycoremediation uses fungi for the same purpose.

Step 3. Give microbe-process examples. Bioventing increases oxygen/air flow to accelerate microbial degradation of pollutants; bioleaching uses microorganisms in solution to recover metal pollutants from contaminated sites; bioaugmentation adds selected microbes to speed up degradation; composting uses microbes to convert solid waste into nutrient-rich manure. …
