Congrats to PhD students Joe Tolar and Siliang Li for their preprint revealing a hybrid extracellular electron transfer mechanism (EET) in Lactiplantibacillus plantarum. In this paper, they discovered that L. plantarum can shift between using quinones or flavins to support EET. Which EET route the cells use depends on L. plantarum‘s access to environmental biomolecules and on the extracellular electron acceptors.
