Gram-positive and gram-negative bacteria use quorum sensing to coordinate population behavior. In several streptococci, quorum sensing mediated by competence-stimulating peptides (CSP) is associated with development of competence for transformation. We show here that a synthetic CSP favored the biofilm mode of growth of Streptococcus intermedius without affecting the rate of culture growth.
革兰氏阳性菌和革兰氏阴性菌利用群体感应来协调群体行为。在几种链球菌中,由感受态刺激肽(CSP)介导的群体感应与转化感受态的发展有关。我们在此表明,一种合成的CSP有利于中间链球菌的生物膜生长模式,而不影响培养物的生长速率。
