Oleaginous yeasts, Yarrowia lipolytica and Lipomyces starkeyi, can synthesize more than 20% of lipids per dry cell weight from a wide variety of substrates. This feature is attractive for cost-efficient production of industrial biodiesel fuel. These yeasts are also very promising hosts for the efficient production of more value-added lipophilic compound carotenoids, e.g., lycopene and astaxanthin, although they cannot naturally biosynthesize carotenoids. Here, we review recent progress in researches on carotenoid production by oleaginous yeasts, which include red yeasts that naturally produce carotenoids, e.g., Rhodotorula glutinis and Xanthophyllomyces dendrorhous. Our new results on pathway engineering of L. starkeyi for lycopene production are also revealed in the present review.
