The School of Biochemical Engineering in IIT of Banaras Hindu University, has claimed to have obtained a new bacterial strain from a contaminated site which has the capability of removing toxic hexavalent chromium from water.
The Hexavalent chromium is a heavy metal ion that could lead to health complications in humans which includes different types of cancers, liver and kidney malfunctioning and even infertility.
Dr Vishal Mishra and Ph.D student Veer Singh said that this bacterial strain can absorb large concentrations of the harmful hexavalent chromium.
Dr Mishra said, “It is very effective for removal of hexavalent chromium from wastewater when compared to other conventional methods. This bacterial strain showed fast growth rate in the Cr (VI) containing aqueous medium and easily separated from the aqueous medium after the water treatment process."
He said that this process is favorable as there is no further need for an extra separation process after its removal from wastewater. They have fully tested the capacity of the bacterial strain both in industrial and synthetic wastewater which proved to be successful.
The research work has been published in ‘Journal of Environmental Chemical Engineering’.
