Give example of role of microorganisms in pollution control. |

Answer» Micro-organisms are well known for their ability to break down a huge range of organic compounds and absorb inorganic substances. Currently, microbes are used to clean up pollution treatment in processes known as ‘bioremediation’. Bioremediation uses micro-organisms to reduce pollution through the biological degradation of pollutants into non-toxic substances. This can involve either aerobic or anaerobic micro-organisms that often use this breakdown as an energy source. Bioremediation technology includes phytoremediation (plants) and rhizoremediation (plant and microbe interaction). At present, the process is used to check contamination in soil, groundwater and surface water. The system does not require construction or any major modification of drains or diversion of flow. It takes place in open drains without displacement of sewage. The process also does not require any additional land or power, making it a simple and easy system. |
