Mineral Specific Biofilm Formation of “Acidibacillus ferrooxidans” Huett2

Abstract:

Recently, a novel acidophilic heterotrophic iron oxidizing bacterium belonging to the newly described genus Acidibacillus (formerly Alicyclobacillus) was isolated from a water drainage ditch in Freiberg, Germany. Bioleaching tests showed that Acidibacillus ferrooxidans Huett2 contributes to the dissolution of minerals. As microbe-mineral interactions play a crucial role in nature and enhance the reaction kinetics of the mineral dissolution, attachment of Ab. ferrooxidans Huett2 on the sulfide minerals pyrite (FeS₂), chalcopyrite (CuFeS₂), and chalcocite (Cu₂S) is in the focus of our current investigations.
