Microbial response to U(VI) and nitrate treatments of uranium mining waste pile samples


Microbial response to U(VI) and nitrate treatments of uranium mining waste pile samples

Selenska-Pobell, S.

Response of microbial community of a depleted uranium waste to treatments with U(VI) and/or nitrate was studied by using molecular methods. The applied 16S rRNA- and narG-gene retrievals, demonstrated that the samples harbour a large number of hidden species inducible by nitrate, some of which are also capable to tolerate U. The changes in bacterial community depended on the salt solutions used and on the aeration condition. The archaeal populations, in contrast, were shifted to one particular group, independently on the art of the treatments. After longer incubations with U(VI) the initial structure of the bacterial community started to recover, indicating that the added U was no longer bio-available.
