Volatile fatty acids and their potential application as feedstock for single‐cell protein production: review and perspectives

Abstract Single‐cell proteins (SCPs) derived from volatile fatty acids (VFAs), an alternative protein source, have recently attracted attention. This review examines VFA production using anaerobic digestion and its integration with aerobic systems for SCP production. It also summarizes recent advances in VFA‐derived SCPs using diverse microorganisms and discusses the prospects of this approach for sustainable protein alternatives.
