Programming the quorum sensing-based AND gate in Shewanella oneidensis for logic gated-microbial fuel cells

Chem Commun (Camb). 2015 Mar 11;51(20):4184-7. doi: 10.1039/c5cc00026b.

Abstract

An AND logic gate based on a synthetic quorum-sensing (QS) module was constructed in a Shewanella oneidensis MR-1 mtrA knockout mutant. The presence of two input signals activated the expression of a periplasmic decaheme cytochrome MtrA to regenerate the extracellular electron transfer conduit, enabling the construction of AND-gated microbial fuel cells.
