Bioremediation and Biodegradation: Importance and Recent Development

摘要: Bioremediation can help reduce and remove the pollution we produce, to provide clean air, water, and healthy soils for future generations. Pollution damages our health and the environment, affecting wildlife and the sustainability of our planet, as summarised in our policy briefing on food security. Under controlled conditions, bioremediation is the process of biologically degrading organic wastes, typically to a state of innocuousness or to concentration levels that remain within particular concentration limits set forth by the controlling authority. In bioremediation, it is possible to do it either ex situ or in situ, depending on a number of factors, such as the type and concentration of pollutants, cost, and/or site characteristics. As a result, ex situ is generally more expensive than in situ, since excavation results in additional expenses. Biological processes are the most effective and economical way to remediate a polluted site …
