| 摘 要： | 生物被膜是一种与浮游细胞相对应的生长方式,由细菌和自身分泌的包外基质组成。铜绿假单胞菌是研究这一生长方式的模式生物。在过去十年,对铜绿假单胞菌生物被膜的研究已取得显著进展。群体感应(QS)的细胞沟通机制在铜绿假单胞菌生物被膜形成中发挥着重要作用。介绍生物被膜的特点,并重点讨论了QS和生物被膜之间的关系。

| Abstract: | Compared with planktonic cells,bacterial biofilm is a kind of particular colonial life style which consists of bacteria and their extracellular matrix.Pseudomonas aeruginosa has become a model organism for studying biofilm formation.Over the past decade,significant strides have been made towards understanding biofilm development in Pseudomonas aeruginosa.Quorum sensing(QS)has been found to play a role in Pseudomonas aeruginosa biofilm formation.This paper introduced the biofilm characteristics,focusing on t... |
