Biotic factor does not limit operational pH in packed-bed bioreactor for ferrous iron biooxidation

Abstract: Ferrous ion biooxidation is a process with many promising industrial applications: mainly regeneration of ferric ion as an oxidizing reagent in bioleaching processes and depuration of acid mine drainage. The flooded packed-bed bioreactor (FPB) is the design that leads to the highest biooxidation rate. In this bioreactor, biomass is immobilized in a biofilm that consists of an inorganic matrix, formed by precipitated ferric compounds, in the pores of which cells are attached. This biofilm covers the surface of … Show more

“…E6-1, 3-8 HM769771 (Figures 3 and 4, tailings and TIF) and Acidithiobacillus sp. NU-1_LC115032 ( Figures 3 and 4, bacterial enrichment) are phylogenetically similar to A. ferrooxidans ATCC19859 [38,39]. The detection of these acidophilic, iron-oxidizing bacteria is consistent with microbial communities from acid mine drainage environments [2,3,10,[17][18][19]21,[40][41][42][43].…”
