Abstract
Isolated, clonal populations of cells are rarely found in nature. The emergent properties of microbial consortia present a challenge for the systems approach to biology, as chances for competition, communication, or collaboration multiply with the number of interacting agents. This review focuses on recent work on intercourse within biofilms, among quorum-sensing populations, and between cross-feeding metabolic cooperators. New tools from synthetic biology allow microbial interactions to be designed and tightly controlled, creating valuable model systems. We address both natural and synthetic partnerships, with an emphasis on how system behaviors derive from the properties of their components. Essential features of microbial biology arose in the context of a very mixed culture and cannot be understood without unscrambling it.
摘要
孤立的、克隆的细胞群体在自然界中很少见。微生物群落的涌现特性对生物学的系统方法提出了挑战，因为随着相互作用的因子数量的增加，竞争、通信或合作的机会也会增加。本综述重点介绍了生物膜内、群体感应种群之间以及交叉喂养代谢合作者之间的最近研究进展。合成生物学的新工具允许设计和严格控制微生物相互作用，从而创建有价值的模型系统。我们既涉及自然的也涉及合成的伙伴关系，重点是系统行为如何源自其组件的特性。微生物生物学的基本特征是在非常混杂的培养环境中出现的，如果不加以梳理，就无法理解。
