Developing Ganoderma lucidum as a next-generation cell factory for food and nutraceuticals

Abstract

Ganoderma lucidum holds a colossal reservoir of hydrolytic enzymes and therapeutic compounds and can be a sustainable source of proteins and bioactive compounds. Its metabolic versatility, propelled by its rich genome content, provides excellent biosynthetic machinery for innovation-driven pathway engineering. However, robust regulatory networks and low frequency of homologous recombination are critical bottlenecks that limit the development of molecular tools and precise genetic markers for biomanufacturing innovations in this organism. Modern synthetic biology provides tools that could help to accelerate precise multiple gene targeting and editing and untangling the biosynthetic machinery of G. lucidum. This review provides insight into molecular strategies to unwind the regulatory bottlenecks and transform G. lucidum into efficient cell factories for food and nutraceuticals.
