Various strategies to accelerate the formation of biofilms on minerals have been studied, and one of them is the use of D-galactose as an inducer of EPS production in planktonic cells of biooxidant bacteria. With the aim to evaluate the influence on

Acidithiobacillus ferrooxidans, together with other microorganisms, has an important role on biohydrometallurgical processes. Such bacterium gets its energy from the oxidation of ferrous ion and reduced sulfur; in the first case, the accumulation of

In biohydrometallurgical processes, a mineral exhibits different oxidation phases due to the system's heterogeneity, especially in heap leach pads. Oxidation chemically modifies the mineral surface altering its interface, and thereby affecting the ba

Chalcopyrite is the main ore mineral used in industrial copper extraction. However, when passivation processes occur during hydrometallurgical treatment, a large percentage of the mineral being treated is not solubilized, so the copper recovery is li

The aim of this work was to use electrochemical methods, capable to follow the corrosion of minerals, in order to monitor the progressive attack of the bacteria on the mineral. The assay was performed in a three electrode cell, with pyrite as the wor

Bacterial cell attachment that results in biofilm formation is the first step of bacteria-mineral interaction, and it is known that they strongly depend on the chemical characteristics of the mineral surface. In some industrial processes, like those

Bioleaching is a process that involves acidophilic and chemolithoautotrophic microorganisms such as Acidithiobacillus ferrooxidans. It is known that At. ferrooxidans undergoes growth and biooxidation inhibition due to ferric ion accumulation. The obj
