Postbiotic emissaries: a comprehensive review on the bioprospecting and production of bioactive compounds by Enterococcus species

Abstract

SummaryEnterococcus species have been acknowledged for their diverse metabolic capabilities, resulting in a wide array of bioactive compounds that show promise for therapeutic use. This article presents a thorough examination of the exploration and synthesis of bioactive compounds by Enterococcus species. It encompasses the taxonomy, natural habitat, and significance in the biotechnology of Enterococcus, emphasising the various bioactive compounds it produces, including antibacterial, immunomodulatory, and antioxidant agents. Strategies for exploring potential bioactivities, encompassing isolation methodologies and screening techniques, are discussed. The biotechnological synthesis of bioactive compounds derived from Enterococcus via fermentation processes, optimisation approaches, and scaling methodologies is expounded. Moreover, the utilisation of these bioactive compounds in functional foods, pharmaceuticals, and agriculture, alongside considerations of safety and regulatory aspects, is examined. The review concludes with future perspectives and challenges in the field of Enterococcus‐derived bioactive compounds.
