New roles for Yarrowia lipolytica in molecules synthesis and biocontrol

Reprogramming of host metabolism is a common strategy for improving desired compounds in host cells and is essential to generate overproducing strains in biotechnology. As a promising feedstock converter, Yarrowia lipolytica has been engineered to extend its bioproduction ability related to the synthesis of new value-added molecules relevant to human food and disease treatment. New synthetic tools have been reported and new enzymes with biotechnological importance are recovered. Additionally, metabolic events occurring during substrate utilization and recombinant protein production have been elucidated. Its contributions as feed and in controlling disease in the food industry have also been provided. Likewise, the recent abilities of Yarrowia lipolytica in the bioconversion of food waste into single-cell protein have been reported. These aforementioned events made the novelty of this review compared to the existing ones on this oleaginous yeast. KEY POINTS: • The production of biolipids by the heterotrophic yeast Yarrowia lipolytica is examined. • A Summary of information concerning new value-added molecules has been highlighted. • Special focus on the importance of Yarrowia lipolytica in regulating the immune system has been provided.
