Regulation of bacterial growth is generally studied in relation to physicochemical conditions ; however, how a bacterial community regulate itself remains obscure. Recently, it was demonstrated that cell-to-cell communication molecules regulate respiration in Pseudomoans aeruginosa. To gain more insight into how growth is regulated in the presence of other bacterial species, the effect of a P. aeruginosa produced cell-to-cell communication molecule on the growth of other bacteria was studied. In conclusion, bacterial signals seem to be a multifunctional molecule affecting other bacterial species ; furthermore, this cell-to-cell communication molecule may influence the bacterial community development by regulating bacterial growth, for which physicochemical factors are important.

细菌生长的调节通常与物理化学条件有关;然而，细菌群落如何调节自身仍然不清楚。最近的研究表明，铜绿假单胞菌的细胞间通讯分子调节呼吸作用。为了更深入地了解在其他细菌物种存在下生长是如何调节的，研究了铜绿假单胞菌产生的细胞间通讯分子对其他细菌生长的影响。总之，细菌信号似乎是影响其他细菌物种的多功能分子;此外，这种细胞间通讯分子可能通过调节细菌生长来影响细菌群落的发育，其中物理化学因素是重要的。
