Predator–Microbe Dynamics Inform Strategies for Robust Synthetic Community Assembly

Environmental Microbiology, Volume 28, Issue 6, June 2026.
This Review introduces ecological principles of predator–prey interactions as a new dimension in SynCom design. By linking microbial defence traits, encounter dynamics, and adaptive buffering, it outlines a framework for constructing predator‐resistant synthetic communities with enhanced resilience, stability, and functional performance under natural ...
