ABSTRACT
The receptors present at/around a contaminated site,
toxicity of the contaminants to the receptors, principal
responsible parties, regulatory bodies, and the concerned
public are factored in defining the target cleanup levels at
any site.[5]
The rate and the extent of bioremediation at a specific
site depend on 1) the presence of microbial population
capable of degrading the contaminants at the site and 2)
the compatibility of physical-chemical and biological con-
ditions at the site for transformation of the contaminants into
non-toxic innocuous compounds. The physical-chemical
conditions include moisture content, pH, temperature,
concentrations of nutrients, carbon source, electron donor
(energy source), electron acceptor, and availability of
contaminants to the microorganisms. Biological conditions
include toxicity of available contaminants to the micro-
organisms and presence of synergistic, competing, and
preying organisms.
