Key Points: Microbial Pollution Control

  • Microbes play a vital role in pollution control by decomposing solid waste, sewage, and toxic pollutants through processes like composting, biogas production, and bioremediation.
  • In landfilling, microbes decompose biodegradable urban waste to form compost, while plastic lining prevents soil pollution due to leaching.
  • During sewage treatment, microbes decompose organic matter, destroy pathogens, release methane and CO₂, and make treated water environmentally safe.
  • Microbes are used in clean technology to remove sulphur from fuels, detoxify metals, and decompose industrial chemicals and xenobiotics.
  • Specialized microbes degrade pollutants such as petroleum oil (hydrocarbonoclastic bacteria), plastics (PET), rubber, acid rain compounds, and uranium salts, thereby protecting soil and water resources.
