Abstract

Anaerobic growth of Pseudomonas aeruginosa PAO1 was affected by quorum sensing. Deletion of genes that produce N-acyl-l-homoserine lactone signals resulted in an increase in denitrification activity, which was repressed by exogenous signal molecules. The effect of the las quorum-sensing system was dependent on the rhl quorum-sensing system in regulating denitrification.

摘要

铜绿假单胞菌PAO1的厌氧生长受群体感应影响。产生N-酰基-L-高丝氨酸内酯信号的基因缺失导致反硝化活性增加，而外源信号分子可抑制该活性。在调节反硝化过程中，las群体感应系统的作用依赖于rhl群体感应系统。
