在殖民地发展过程中，细菌产生了丰富的模式，其中一些模式让人想起那些发生在非生物系统中的模式。它们可以表现出丰富的行为，反映出信息交流的能力，包括遗传物质的交换和群落的组成部分是生物的事实。每个细菌都有内部自由度、信息学能力和通过自我调节的信号发射改变自己和他人的自由。为了揭开细菌自组织的特殊秘密，我们对非生物和生物系统进行了综合(实验和理论)研究。在一般生物动机和原则的指导下，我提出，个体之间的信息交流使个体之间的调节自由的增强成为可能，同时加强他们之间的合作。这一过程是通过分层时空模式的自组织使群体协同复杂化来完成的。殖民地更高的复杂性提供了在动态环境中更好地适应和耐受殖民地所需的可塑性和灵活性程度。生物系统可以改变环境，获得环境信息，以便进一步自我改进。我对新理解的潜在应用进行了思考，这些新理解涉及“复杂到无法设计的系统的工程化自组织”和其他问题。
During colonial development, bacteria generate a wealth of patterns, some of which are reminiscent of those occurring in abiotic systems. They can exhibit rich behaviour, reflecting informative communication capabilities that include exchange of genetic materials and the fact that the colony's building blocks are biotic. Each has internal degrees of freedom, informatic capabilities and freedom to respond by altering itself and others via emission of signals in a self-regulated manner.To unravel the special secrets of bacterial self-organization, we conducted an integrative (experimental and theoretical) study of abiotic and biotic systems. Guided by the notion of general biotic motives and principles, I propose that the informative communication between individuals makes possible the enhancement of the individuals' regulated freedom, while increasing their cooperation. This process is accomplished via cooperative complexification of the colony through self-organization of hierarchical spatio-temporal patterning. The colonial higher complexity provides the degree of plasticity and flexibility required for better colonial adaptability and endurability in a dynamic environment. The biotic system can modify the environment and obtain environmental information for further self-improvement. I reflect on the potential applications of the new understanding on 'engineered self-organization of systems too complex to design' and other issues.
