摘要：Self-organization is a characteristic feature of living systems that exist far from thermodynamic equilibrium or dissipative dynamics. The establishment of such a state, far from thermodynamic equilibrium, relies on the constant supply of energy. This phenomenon is evident in biological systems, ranging from sub-cellular components to multicellular organisms. Our objective is to deepen the understanding of living active matter self-organization by employing motile bacteria as a model system. During this presentation, I will highlight several captivating instances of ordering observed in biofilm-based active systems, which emerge solely from physical interactions. Additionally, I will explore the potential advantages that bacterial communities can gain from these ordering mechanisms. The insights obtained from these investigations hold significance for non-equilibrium physics, microbial physiology, and the field of active matter engineering.
