Advances in metabolic engineering of non-conventional yeasts

Abstract:

Over the past 30 years, Yarrowia lipolytica, Kluyveromyces, Pichia, Candida, Hansenula and other non-conventional yeasts have attracted wide attention because of their desirable phenotypes, such as rapid growth, capability of utilizing multiple substrates, and stress tolerance. A variety of synthetic biology tools are being developed for exploitation of their unique phenotypes, making them potential cell factories for the production of recombinant proteins and renewable bio-based chemicals. This review summarizes the gene editing tools and the metabolic engineering strategies recently developed for non-conventional yeasts. Moreover, the challenges and future perspectives for developing non-conventional yeasts into efficient cell factories for the production of useful products through metabolic engineering are discussed.
