Comparative genomics in acid mine drainage biofilm communities reveals metabolic and structural differentiation of co-occurring archaea [PDF]

, 2016
Background Metal sulfide mineral dissolution during bioleaching and acid mine drainage (AMD) formation creates an environment that is inhospitable to most life. Despite dominance by a small number of bacteria, AMD microbial biofilm communities contain a

EPS-contact-leaching mechanism of chalcopyrite concentrates by A. ferrooxidans

Transactions of Nonferrous Metals Society of China, 2008
Abstract The effect of extracelluar polymeric substances(EPS) on the bioleaching chalcopyrite concentrates in the presence of iron- and sulphur-oxidizing bacteria ( A. ferrooxidans ) was studied. The bacterial number, pH, redox potential, and the concentrations of Fe 2+ and Cu 2+ ions were investigated.
