Membrane vesicles as a novel strategy for shedding encrusted cell surfaces

Rizlan Bernier-Latmani, Paul Pao-Yun Shao

Surface encrustation by minerals, which impedes cellular metabolism, is a potential hazard for microbes. The reduction of U(VI) to U(IV) by Shewanella oneidensis strain MR-1 leads to the precipitation of the mineral uraninite, as well as a non-crystalline ...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Rizlan Bernier-Latmani, Romain Hamelin, Diego Chiappe, Elena Suvorova Buffat, Elena Cristina Dalla Vecchia, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

Combined scanning transmission X-ray and electron microscopy for the characterization of bacterial endospores

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Paul Pao-Yun Shao, Imrich Barak, Jan Jamroskovic

Endospores (also referred to as bacterial spores) are bacterial structures formed by several bacterial species of the phylum Firmicutes. Spores form as a response to environmental stress. These structures exhibit remarkable resistance to harsh environmenta ...

Biogeochemical controls on the product of microbial U(VI) reduction

Rizlan Bernier-Latmani, Daniel Scott Alessi, Malgorzata Alicja Stylo, Paul Pao-Yun Shao

Biologically mediated immobilization of radio-nuclides in the subsurface is a promising strategy for the remediation of uranium-contaminated sites. During this process, soluble U(VI) is reduced by indigenous microorganisms to sparingly soluble U(TV). The c ...
