<h3>What is Bioremediation ?</h3>

A subfield of biotechnology called "bioremediation" uses living things like bacteria and microorganisms to clean up contaminated environments. It is used to clean up poisons, pollutants, and other contaminants from water, soil, and other habitats.

  • Bioremediation refers to the removal of biological fluids and blood that may include pathogens like hepatitis, HIV, and MRSA or pose other health problems. Crime scene cleaners employ enzyme cleansers rather than conventional cleaning products like bleach or ammonia to get rid of dangerous compounds from the site.

  • Microbial bioremediation, phytoremediation, and mycoremediation are a few of the most popular types of bioremediation.
