The Use of Microorganisms In Bioremediation Of Heavy Methals In Soils

Bioremediation is an promising and available new technique for removal and recovery of heavy metals in contaminated land and waters. These microorganisms developed Different detoxifying mechanisms such as bioaccumulation, biosorption, biomineralization and biotransformation.The food and water we consume are often pulluted very of chemicals and heavy metals, such as gold,copper ,nickel, zinc, cadmium, arsenic, lead, chromium, and mercury that are associated with very diseases.Some studies described microorganism able to bioremediation heavy methas. Among others some of the microorganisms that play great role in bioremediation of heavy metals are Pseudomonas spp ,Corynebacterium spp ,Bacillus spp Arthrobacter spp, Alcaligenes spp, Rhodococcus spp, Flavobacterium spp, Nocardia spp, Azetobacter spp, Methosinus, Phormidium valderium.
