Abstract:Lactiplantibacillus plantarum is known to utilize exogenous small molecule quinone mediators to perform extracellular electron transfer (EET), which allows it to produce a detectable current in a bioelectrochemical system. Utilization of quinone mediators by L. plantarum requires a type-II NADH dehydrogenase (Ndh2), however small structural variations in the core of 1,4-naphthoquinone EET mediators yields significantly different current outputs. Herein, we assembled a library of 30 naphthoquinone-based EET med… Show more
