Enzyme-Based Biodegradation of Hazardous Pollutants – An Overview

There has always been a paramount concern over the widespread occurrences of various pollutant types, around the globe. With ever increasing scientific knowledge, socio-economic awareness, human health problems and ecological apprehensions, people are more concerned about the widespread environmental pollutants. Thus, the occurrences of newly identified pollutants so-called -emerging pollutants -EPs or emerging contaminants -ECs in our main water bodies is of continued and burning concern worldwide. The undesirable EPs/ECs are being discharged knowingly/unknowingly with/without partial treatments into the aquatic environments that pose serious health issues and affect the whole living ecosystem. So far various approaches have been developed for the degradation of environmental pollutants to decrease their impact on the environment and are divided into three broad categories i.e.
