These concentrations are highly variable, and depend on both the algal species and the host environments.
. These results endorse the premise that microorganisms mediate the transfer of many solutes between hydrosphere and sedimentary regime, and by sequestering toxic metals released from the mine tailings, they are useful in the retardation of metal dispersion into the environment and as a possible mechanism to enhance secondary recovery of precious metals where solute levels are too low for conventional technology.
