        Abstract Synthetic microbial consortia are a rapidly growing area of synthetic biology. So far, most consortia are designed without considering their environments; however, in nature, microbial interactions are constantly modulated by cellular contexts, which in principle can alter community behaviors dramatically. Here we present the construction, validation and characterization of an engineered bacterial predator-prey consortium that involves a chloramphenicol(CM)-mediated, context-dependent cellular interaction. By conducting the experiments and the simulations of mathematical models, we show that varying the CM level in the environment can induce the ecosystem to success with distinct patterns from prey dominance to prey-predator crossover and to ecosystem collapse, We also illustrate that such a dependence enriches community dynamics under different initial conditions and further test the resistance of the consortium to invasion with engineered bacterial strains. This workexemplifies the role of the context-dependence of microbial interactions in moderating ecosystem dynamics, underscoring the importance to include contexts into the design of engineered ecosystems for synthetic biology applications.
