BIOREMEDIATION OF METAL
CONTAMINATED ENVIRONMENT: A REVIEW
M
etal contaminants cause specific toxicity at higher concentration in envi-
ronment, by altering the nucleic acids conformation, proteins and inter-
ference with oxidative phosphorylation. The soil sources of heavy metals are
metal-rich mine tailings, electroplating, gas exhaust, energy and fuel produc-
tion, weathering of minerals, erosion, volcanic activity, downwash from power
lines, intensive agriculture use of pesticides, phosphate fertilizer discharge,
biosolids (e.g., livestock manures, composts, and municipal sewage sludge),
and sludge dumping. Managing these wastes due to urbanization/population
explosion in developing countries is a challenge due to toxins released. Dump-
ing industrial wastes affects all living creatures, losing biodiversity. Biotechno-
logical approaches as disparaging bioaugmentation, land farming, bio pilling
is used to degrade the heavy metals. Their toxic effect on kidneys, nervous
system, may lead to the symptoms of mental disorder, weakness, headaches,
abdominal cramps, diarrhea, anemia and in certain cases even permanent
damage of the organelles. Streptomyces sp bioremediated heavy metals from
waste water to a great extent, viz Mn
