Roles and responsibilities

My research role is to find biotechnological ways for carbon sequestration in mine tailings/slags as well as to recover critical minerals for circular economy. I work to develop innovative biotechnological approaches for the remediation of metallurgical waste generated by mine industries includes microbial bio-oxidation-reduction, biocyanidation, bioflocculation and bioflotation.

Current research and/or projects

Project 1: Hybrid biotechnology for mineral carbonation in mine tailings

The process of carbon mineralization has been identified as one of the most promising strategies dedicated to the removal of CO2 from the atmosphere. Among these processes, the ex-situ mineralization of alkaline materials contained in mine tailings is particularly appealing. Researchers have estimated that in Quebec only, approximately 1.7 million tons of atmospheric CO2 have been passively captured by serpentine tailings. From USGS (2018), ultramafic mine tailings have a dynamic storage capacity of 7,000,000 tCO2/yr. For mineral carbonation, mining and metallurgical wastes need to contain divalent metals, and some pre-treatments of the wastes have been shown to accelerate CO2 capture by enhancing mineral dissolution. Our project plans to develop a biotechnology using microorganisms to catalyze CO2 carbonation, forming stable metal carbonates. Cavitation treatments will be used to improve the grindability of the material, thus reducing its size and viscosity, and along with organic-acid producing microorganisms, to improve both carbonate precipitation and simultaneous critical minerals recovery by increasing dissolution of the mineral matrix. Encapsulation of bacteria and the use of immobilized microbial enzymes will be tested to improve and stabilize the biological process. New innovative technologies exploiting mineralogical matrices must be supported by advanced geochemical and mineralogical investigation, which will be developed, adapted and optimized.


Project 2: Mechanistic Understanding of Acidophilic Electroactive Biofilms

Most bacteria are capable of forming surface-associated, architecturally complex communities, known as biofilms. The so-called electroactive biofilms possess the unique metabolic feature that enables electroactive microorganisms to use solid-state electron donors or acceptors such as electrodes (man-made systems) or sulfide minerals (natural ecosystems). Electroactive biofilms have been exploited in biotechnology for the production of chemicals as well as towards biofuels, biohydrogen and electricity production in microbial fuel cells. However, the role of natural acidophilic biofilms in acid rock drainage production and for improving biohydrometallurgical processes has not been investigated yet. In general, there is a gap of knowledge on the reactions inside biofilms and electrochemical reactions (no established electrochemical theory of biofilms). The exact mechanisms of extracellular electron transfer between microorganisms and solid substances remain a matter of intensive debate. Harnessing the catalytic activities of electroactive biofilms will ultimately require deep understanding of how biofilm cells transfer electrons across the surface-attached multilayered community. Three different routes for direct electron transfer between microbial assemblages and solid surfaces have been proposed: (i) via redox proteins located on the bacterial membrane (e.g. metalloproteins), (ii) via redox compounds excreted from the bacteria (e.g. siderophores), and (iii) via conductive nanowires that interconnect bacterial cells to the solid surface. A proteomic-based approach will be used to elucidate the physiology and molecular mechanisms participating in electron transfer in acidophilic biofilms during sulfide mineral oxidation processes. Advanced techniques will also be used to tentatively measure the kinetics of redox mediators inside biofilms, resolving local concentrations of chemical species inside the biofilm and resolving the physical location of electrochemically active species. Interactive associations among metabolically cooperative bacterial populations will also be investigated.
