“…pre-grown in an airlift fermenter produced catalytically active Pd(0) (Deplanche, 2008) while studies using E. coli grown aerobically attributed reduction of Pd(II) to formate dehydrogenases FDH-O and FDH-N (Foulkes, J., personal communication). Extensive studies of Pd(0) deposition on cells of the aerobic Bacillus sphaericus assumed metal deposition onto the cell surface S-layer (Fahmy et al, 2006) and the resulting material had a similar catalytic activity in hydrogenation of itaconic acid as Desulfovibrio bioPd(0) (Creamer et al, 2007). However, further study showed deposition of Pd(0) below the S-layer and within the inner cell surface layers (Skibar et al, 2005) and an additional mechanism was implicated.…”

Surface-layers (S-layers) are macromolecular paracrystalline arrays of proteins or glycoproteins that can self-assemble into 2-dimensional semi-permeable meshworks to overlay the cell surface of many bacteria and archaea. They usually assemble into lattices with oblique, square or hexagonal symmetry and serve as an interface between the bacterial cell and the environment. Isolated S-layers can recrystallize into two-dimensional regular arrays in suspension or on various surfaces, thus being an appropriate material for several bionanotechnological purposes. Promising applications of S-layers include their use as biotemplates for the capture of metal ions or the synthesis of metal nanoclusters. Research ArticleInternational Journal of Biochemistry Research & Review, 3(1): 39-62, 2013 40 Considering the use of S-layers as biotemplates for the organization of metal ions or metallic nanoclusters, research on potential of surface layer proteins (SLP) and metals can be understood as an interdisciplinary field, in which different biophysical techniques supply complementary information. In this review, we discuss the SLP as native or engineered "bottom-up" building blocks for metal immobilization structures. We also describe the biophysical techniques used to analyze metal binding properties as well as the information obtained from the investigation of these structures.

“…The use of S-layer proteins as a template allow a reliable immobilisation and arrangement of the nanoparticles into array structures. Due to their intrinsically high surface-to-volume ratio, such nanomaterials are attractive for catalytic or sensor applications [72][73][74][75].…”

Novel Biotechnological Approaches for the Recovery of Metals from Primary and Secondary Resources

Abstract:Microorganisms have developed various mechanisms to deal with metals, thus providing numerous tools that can be used in biohydrometallurgical processes. "Biomining" processes-including bioleaching and biooxidation processes-facilitate the degradation of minerals, accompanied by a release of metals. These processes are especially attractive for low-grade ores and are used on an industrial scale mainly for sulfidic ores. In biosorption processes, biomass or certain biomolecules are used to bind and concentrate selected ions or other molecules from aqueous solutions. Biosorptive materials can be an environmentally friendly and efficient alternative to conventional materials, such as ion exchange resins. Other interesting mechanisms are bioaccumulation, bioflotation, bioprecipitation, and biomineralisation. Although these processes are well-known and have been studied in detail during the last decades, the recent strong progress of biotechnologies (e.g., genetic engineering and molecule design), as well as their combination with novel developments in material sciences (e.g., nanotechnologies) facilitate new strategies for the application of biotechnologies in mineral processing. The article gives a summary of current activities in this field that are being performed in our group.
