N -Acyl- l -Homoserine Lactone Quorum Sensing Controls Butanediol Fermentation in Serratia plymuthica RVH1 and Serratia marcescens MG1

Abstract
Butanediol fermentation in two Serratia species is shown to be affected by N -acyl- l -homoserine lactone-dependent quorum sensing. Knockout of quorum-sensing signal production caused a shift towards enhanced acid production, resulting in early growth arrest, which was reversible by the addition of synthetic signal molecules.
