With the development
of release of heavy metals into the environment is increasing. The abundant use
and increase the level of concern is serious. Biotechnology, bioremoval heavy
metals from industrial wastewater by using microorganisms' ability to be an
efficient, environmentally friendly and developing effective. Identify bacteria
resistant to toxic metals that have the potential in this area are technically
complex and useful. The use of hallophilic bacteria due to having special
features, high power stability important in biological cleaning of metal
compounds in natural environments play. Biological removal of toxic metal
cadmium with high, environmental movement as an important field of
biotechnology. Optimization of environmental conditions whose removal increases
the efficiency should be considered further. The aim of this study reviews the
removal of cadmium by bio-dispersion.
And the impact of environmental factors on biological uptake of heavy
and compare them with other bioabsorbents.
