Bioremediation refers to the clean-up of pollution in soil,
groundwater, surface water, and air using typically microbiological
processes. It uses naturally occurring bacteria and fungi or plants
to degrade, transform or detoxify hazardous substances to human
health or the environment. For bioremediation to be effective,
microorganisms must enzymatically attack the pollutants and convert
them to harmless products. As bioremediation can be effective only
where environmental conditions permit microbial growth and action,
its application often involves the management of ecological factors
to allow microbial growth and degradation to continue at a faster
rate. Like other technologies, bioremediation has its limitations.
Some contaminants, such as chlorinated organic or high aromatic
hydrocarbons, are resistant to microbial attack. They are degraded
either gradually or not at all, hence, it is not easy to envisage
the rates of clean-up for bioremediation implementation.
Bioremediation represents a field of great expansion due to the
important development of new technologies. Among them, several
decades on metagenomics expansion has led to the detection of
autochthonous microbiota that plays a key role during
transformation. Transcriptomic guides us to know the expression of
key genes and proteomics allow the characterization of proteins
that conduct specific reactions. In this book we show specific
technologies applied in bioremediation of main interest for
research in the field, with special attention on fungi, which have
been poorly studied microorganisms. Finally, new approaches in the
field, such as CRISPR-CAS9, are also discussed. Lastly, it
introduces management strategies, such as bioremediation
application for managing affected environment and bioremediation
approaches. Examples of successful bioremediation applications are
illustrated in radionuclide entrapment and retardation, soil
stabilization and remediation of polycyclic aromatic hydrocarbons,
phenols, plastics or fluorinated compounds. Other emerging
bioremediation methods include electro bioremediation,
microbe-availed phytoremediation, genetic recombinant technologies
in enhancing plants in accumulation of inorganic metals, and
metalloids as well as degradation of organic pollutants,
protein-metabolic engineering to increase bioremediation
efficiency, including nanotechnology applications are also
discussed.
