The cyanobacterium Anabaena doliolum Ind1 isolated from a coal mining site was tested for removal of cadmium at optimum pH 70 and temperature 25˚C The organism recorded high percentage of metal removal (92-69%) within seven days of exposure to 05-20 ppm cadmium Biosorption onto the cell surface was the primary mode of metal removal.
Due to the progressive development of industrial and technological activities, heavy metal contamination is increasing each year and it poses a serious health and environmental risk Microorganisms are capable of removing heavy metals from a contaminated environment In this work, 51 microbial strains were isolated from heavy metal contaminated water and soil.

Cadmium occurs in nature as cadmium sulphide in greenockite, CdS, which is very rare It is widely diffused in calamine, blende, and other zinc ores, forming, in some cases, as much as 2 or 3 per cent, of the ore Oxide of cadmium forms the “ brown blaze ” of the zinc smelters Sulphide of cadmium is used as a pigment (cadmium yellow); and the metal and some of its salts are useful reagents.
