DYNAMICS OF BACTERIAL COMMUNITIES MEDIATING THE TREATMENT OF AN AS-RICH ACID MINE DRAINAGE IN A FIELD PILOT
Laroche, E., C. Casiot, L. Fernandez-Rojo, A. Desoeuvre, V. Tardy, O. Bruneel, et al.
Frontiers in Microbiology 9:3169(2018)
Bacterial diversity was characterized in a field-pilot bioreactor treating extremely arsenic (As)-rich acid mine drainage (AMD) in situ over a 6-month monitoring period. Over the monitoring period, iron (Fe)-oxidizing bacteria dominated the biogenic precipitate. Parameters that exerted a control on the bacterial communities potentially involved in the water treatment process included dissolved oxygen, temperature, pH, dissolved sulfates, arsenic and Fe(II) concentrations and redox potential. The ubiquity and the physiological diversity of the bacteria identified, as well as the presence of bacteria of biotechnological relevance, suggested that this treatment system could be applied to the treatment of other AMD.
