Abstract

In the current scenario, pollution of soil, surface water, and groundwater, with toxic chemicals due to industrialization, is one of the global concerns for the sustainable development of human beings. Thus, the eradication of toxic organic and inorganic pollutants from the contaminated environment is the need of global concern to advance the sustainable development with low environmental impact. The treatment of contaminated soil, sediment, and water by the conventional method is found to be unfeasible due to its high cost and generates secondary pollutants. Therefore, bioremediation has emerged as a natural, economic, sustainable approach which can restore the contaminated soil, surface water, and groundwater, with the help of biological agents like bacteria, fungi, and other organisms or their enzymes. It is an evolving green technology where microbes are grown in the presence of contaminated soil, sediment, surface, and groundwater to elevate the decomposition and/or removal of inorganic and organic pollutants. Bioremediation technologies can be broadly categorized into two categories, i.e., in situ bioremediation and ex situ bioremediation. In situ bioremediation involves treatment of contaminated substances at the same place, whereas ex situ bioremediation involves the elimination of the contaminated material which is treated somewhere else. Some typical examples of bioremediation technologies involve bioventing, biosparging, bioaugmentation, land farming, composting, and biostimulation. This book chapter gives a gist about bioremediation, its strategies, factors affecting biodegradation processes, and advantages and disadvantages of bioremediation.
