A New Protocol for Analysis of Metal Absorption Capacity of Cyanobacteria

Abstract

Cyanobacteria are one of the microorganisms that have high potential for removing heavy metals from the soil and water. They can sequester heavy metal ions in a short period of time through adsorption and absorption mechanisms .In the present investigation, we have studied about metal absorption capacity of cyanobacteria using new method and new instrument Electrolyter-1005,developed by the authors. From the result, it was concluded that Calothrix sp. is more efficient than Anabaena sp. for removal of HgCl₂; so far their EC₅₀ value is concerned. It is also concluded that OAEAGPS value is useful in selection of species for industrial bioremediation programs. This Electrolyter-1005 instrument is very cost effective so that it can be useful for microbiologist and environmentalist in their research purposes.
