Redox transformations of iron at extremely low pH: fundamental and applied aspects

open access: yesFrontiers in Microbiology, 2012
Many different species of acidophilic prokaryotes, widely distributed within the domains Bacteria and Archaea, can catalyze the dissimilatory oxidation of ferrous iron or reduction of ferric iron, or can do both.

Bacterial bioleaching of low grade nickel limonite and saprolite ores by mixotrophic bacteria

open access: yesE3S Web of Conferences, 2016
Utilization of indigenous bacteria should be considered to establish a successful biohydrometallurgical process. In this study, mixrotrophic iron-oxidizing bacterial consortia consisting of Comamonas testosteroni, Alicyclobacillus ferrooxydans and ...

Chemotactic transduction in biomining microorganisms

open access: yesHydrometallurgy, 2001
The oxidative attack of ores by bioleaching microorganisms requires that the cells adhere to specific sites on the surface of the minerals. This attachment will depend on the sensing by the microoganisms of a dissolved ion concentration gradient present in the immediate vicinity of the solid. Chemotactic responses towards metal ions and other compounds
