A stress-response-recovery framework integrating microbial life-history strategies for stressed anaerobic digestion

Key Points

• This study aims to propose a framework for understanding how microbial strategies respond to stress in anaerobic digestion.
• Developed a stress-response-recovery framework for anaerobic digestion.
• Analyzed microbial response strategies including physical and metabolic adaptations.
• Examined recovery dynamics reflecting ecological principles of redundancy and memory.
• Identified key microbial strategies that sustain anaerobic digestion under stress.
• Demonstrated that recovery trajectories exhibit ecological hysteresis.
• Proposed ecological-based monitoring as a complementary method for managing stressed anaerobic digestion.
