Microorganisms usually co-exist in highly complex communities, undertaking distinct roles, depending on the population density, the environmental conditions and resource availability. Despite lack of fundamental understanding how these communities are formed and then sustained, they were successfully used in biotechnological processes like fermentation, waste treatment, and agriculture. Communities are responsible for a specific set of (metabolic) tasks that would be unattainable by an individual organism alone. Moreover, due to numerous interactions among their members, microbial communities achieve very complex functions. Understanding and exploiting these communal capabilities is an emerging field in synthetic biology closely linked to the Microbial Consortia Engineering (MCE) field . Although the majority of the biotechnological approaches exploit the mutualistic/synergistic nature of microbe interactions, examples of synthetic communities investigating the predator-prey relationship exist .
