The demand for the development of eco-friendly, sustainable, and adaptable technologies for the disinfection of the environmental contaminants is increasing nowadays. Nano-bioremediation is one such technique that has made possible the use of biosynthetic nanoparticles for soil pollution remediation. It is an effective, efficient, and feasible method for revitalizing soil potential and rendering it pollution free. Pollutants present in soil are a great threat to soil biota, environment, and in fact human health. Nanomaterials exhibit the unique chemical and physical properties because of which they have always received attention in the growing era of bioremediation. Use of nanotechnology for bioremediation is one such technology as it focuses mainly on the interaction between the contaminants, the microorganisms, and the nanomaterials being used for both the positive (i.e., stimulating) and negative or toxic environmental effects. Thus, this chapter focuses on the need to recover the polluted soil and application of nano-remediation technology for restoring soil's cultivation capacity.

Groundwater is an important part of the human living space and supplies us with high-quality freshwater resources. However, the intrusion of any foreign matter into groundwater may cause groundwater pollution. Once this happens, clearing, control and remediation can be very difficult: not only does it need a lot of money, it is also technically challenging and time consuming. In view of current research on groundwater remediation in and out of China, we propose a package of groundwater pollution investigation, groundwater pollution remediation technology and groundwater pollution control processes with a view to providing theoretical reference for future groundwater pollution remediation efforts.

The universal microbial cometabolism provides us with an effective approach to remove man-made xenobiotics. However, the cometabolic bioremediation of toxic organic compounds has not been widely initiated due to the obscure underlying fundamentals in the studies or applications of microbial cometabolism. This review summarizes the current research trends in mechanistic understanding of microbial cometabolism, especially with regard to its potential applications. The crucial factors including key enzyme, enzyme inhibition, toxic effects and energy regulation are discussed, which all significantly contribute to the cometabolic bioremediation of pollutants. The presented review of chlorinated ethylene cometabolism in this overview has further confirmed the fundamentals and hypotheses mentioned above, and thus cometabolism of chlorinated ethylenes has been regarded as a role model of pollution remediation technology using microbial cometabolism. The subsequent prospective research should provide insights into the ambiguous mechanism of microbial cometabolism and help us to develop more efficient bioremediation of progressive pollution.
