在水处于液态的任何地方,细菌都会以生物膜的形式存在,这些生物膜是由粘合在一起的复杂细胞群落组成的。尽管生物膜经常与疾病和生物污垢有关,但它在工程应用中也很重要,如生物修复、生物催化和微生物燃料电池。在这里,我们回顾了改变遗传电路和细胞信号以控制生物膜形成的方法,并强调将这些工具用于工程应用。基于对生物膜形成的遗传学基础的更好的理解,我们发现生物膜可以通过操纵细胞外信号来控制,并且它们可以通过保守的细胞内信号和调节因子来分散。生物膜也可以在特定的地方形成,在那里它们可能被设计成制造化学品或治疗人类疾病。
Anywhere water is in the liquid state, bacteria will exist as biofilms, which are complex communities of cells cemented together. Although frequently associated with disease and biofouling, biofilms are also important for engineering applications, such as bioremediation, biocatalysis and microbial fuel cells. Here we review approaches to alter genetic circuits and cell signaling toward controlling biofilm formation, and emphasize utilizing these tools for engineering applications. Based on a better understanding of the genetic basis of biofilm formation, we find that biofilms may be controlled by manipulating extracellular signals and that they may be dispersed using conserved intracellular signals and regulators. Biofilms could also be formed at specific locations where they might be engineered to make chemicals or treat human disease.
