[Recent advances in metabolic engineering of microorganisms for production of tyrosol and its derivatives].

Tyrosol is a natural phenolic compound with antioxidant, anti-inflammatory and other biological activities, serving as an important precursor of high-value products such as hydroxytyrosol and salidroside. Therefore, the green and efficient biosynthesis of tyrosol and its derivatives has become a research hotspot in recent years. Building cell factories by metabolic engineering of microorganisms is a potential industrial production way, which has low costs and environmental friendliness. This paper introduces the biosynthesis pathway of tyrosol and presents the key regulated nodes in the synthesis of tyrosol in and . In addition, this paper reviews the recent advances in metabolic engineering for the production of hydroxytyrosol and salidroside. This review can provide a reference for engineering the strains for the high-yield production of tyrosol and its derivatives.
