(Covino et al. 2016) or ligninolytic fungi (see Chap. 22) can be a solution for PCB
remediation (Čvančarová et al. 2012; Stella et al. 2017).
21.4 Nanobioremediation
Although many technologies are available for the remediation of contaminated sites,
the use of a single technology for remediation of recalcitrant contaminants may be
expensive and not effective (Singh et al. 2013; Němeček et al. 2016). The combination of two or more different technologies in sequence is a possible solution for
cost reduction (He et al. 2009) and the acceleration of site rehabilitation.
Nanobioremediation integrates two remediation technologies and the use of
nanomaterials, e.g., iron, followed by bioremediation to gain effective, efficient,
and sustainable remediation technology (Cecchin et al. 2017).
Singh et al. (2013) evaluated the effect of an integrated technique involving the
use of stabilized Pd/Fe
0 bimetallic nanoparticles (CMC-Pd/nFe
0 ) and Sphingomonas
sp. strain NM05, on the degradation of γ-HCH in soil. The integration showed
synergistic effect on γ-HCH degradation, 99% degradation was achieved within six
days of incubation.
21.5 Conclusion
Despite the significant increase in the use of oxidative and reductive technologies
over recent decades, biotechnologies still play an irreplaceable role in the field of soil
remediation. Even though quick site rehabilitation is usually required, biotechnology
will always offer an inexpensive and waste-free solution for a great deal of contaminated sites.
