how Bacillus subtilis and Pseudomonas aerogenosa address the issue of removal of heavy metals from the wastewater?

I am seeking expertise to help me understand how Bacillus subtilis and Pseudomonas aerogenosa address the issue of removal of heavy metals and pollutants from both natural environments and industrial wastewater. By examining the adaptive properties of these species, I intend to gain an understanding of the potential role they can play in helping decrease the concentrations of the heavy metals and pollutants found in these environments. Knowledge gained will be applied to help improve the technical, economic and environmental sustainability of the treatment of these sources. This research is necessary to ensure that any proposed solutions pose no unforeseen risks and are appropriate to the unique conditions of the site in question.
