Abstract: The
idea of bioremediation is with the nature itself. Due to contamination in a
particular region, some organisms may die, growth of few others might on the
contaminants by metabolizing it. Bioremediation would thrive well on the
contaminants by metabolizing it. Bioremediation would involve identification of
such organisms and fostering their growth, naturally or by inoculation, so as
to breakdown the contaminants into less harmful metabolites. This technology
being cheaper and nature friendly is certainly a technology for future. But,
like other technologies this too is not a panacea to all the maladies of
environmental contaminants; toxic metals like cadmium obliterate complete flora
and fauna of the contaminated area and hence it is not possible to use
biological agents to treat them. Microbes require oxygen as an electron
acceptor hence in aqueous phase; oxygen concentration below 1mg/1 restricts the
process of bioremediation.
