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.
研究表明,两种沙雷氏菌属细菌中的丁二醇发酵受N-酰基-L-高丝氨酸内酯依赖性群体感应的影响。群体感应信号产生的敲除导致向增强产酸的转变,从而导致早期生长停滞,而添加合成信号分子可使其恢复。
