| Research Abstract |
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.
