High-throughput isolation of anaerobic arsenic-transforming microorganisms

Arsenic (As) is a toxic metalloid that occurs naturally and is widely distributed in the environment. The inorganic compounds arsenite (As(III)) and arsenate (As(V)) are the most prevalent As species in the biosphere, the former being predominant in reduci ...

Biosensor-aided isolation of anaerobic arsenic-methylating bacteria from soil

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Nicolas Louis Maurice Jacquemin, Hugo Sallet

Microbial methylation of arsenic impacts both the toxicity and fate of this environmental contaminant, and is an important component of its biogeochemical cycle. This transformation occurs in flooded paddy fields where soil microorganisms can produce dimet ...

High-throughput cultivation and isolation of environmental anaerobes using selectively permeable hydrogel capsules

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Nicolas Louis Maurice Jacquemin, Hugo Sallet

Over the past two decades, metagenomics has greatly expanded our understanding of microbial phylogenetic and metabolic diversity. However, most microbial taxa remain uncultured, hindering research and biotechnological applications. Isolating environmental ...

Growth substrate limitation enhances anaerobic arsenic methylation by Paraclostridium bifermentans strain EML

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Hugo Sallet, Jiangtao Qiao

Microbial arsenic methylation is established as a detoxification process under aerobic conditions (converting arsenite to monomethylated arsenate) but is proposed to be a microbial warfare strategy under anoxic conditions due to the toxicity of its main pr ...
