Propionate production and consumption are influenced by thermodynamic constraints, microbial competitions, and metabolic inhibition. Accumulation of propionate in wastewater can destabilize anaerobic digestion and lead to process failure. Anaerobic digestion is one of the viable biological methods for its recovery and utilization. Additives have been shown to modulate propionate production and consumption, effectively influencing the overall performance of anaerobic digestion. This mini review systematically examines the application of various additives and their effects on: (I) propionate production and recovery (less CH₄ and more propionate) and (II) propionate degradation (less propionate and more CH₄) goals in anaerobic digestion. This review studied and listed recent studies on the most used anaerobic digestion additives and classified them according to their impact on propionate concentration. To our knowledge, limited research has been conducted on the role of additives in propionate recovery. No studies have reviewed the impact of additives on propionate recovery from anaerobic digestion or their potential to mitigate its inhibitory effects. This mini review enables researchers to select the most suitable additive to recover propionate or boost CH₄ production by mitigating its inhibition, as well as discussing the role of modern bioreactors.
