1.1.1.34 nutrition engineering of Yarrowia lipolytica for de novo production of the food and feed additive astaxanthin by fermentation. The astaxanthin-producing Yarrowia lipolytica shows great promise for employment in biological astaxanthin production. The genes for beta-carotene biosynthesis: bi-functional phytoene synthase/lycopene cyclase (crtYB) and phytoene desaturase (crtI) from Xanthophyllomyces dendrorhousa are introduced. The activities of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG1) and geranylgeranyl diphosphate synthase (GGS1/crtE) in the best producing strain are optimized. Downregulation of the competing squalene synthase SQS1 increases the beta-carotene titer. Then a beta-carotene ketolase (crtW) from Paracoccus sp. N81106 and hydroxylase (crtZ) from Pantoea ananatis are introduced to convert beta-carotene into astaxanthin. The constructed strain accumulates 10.4 mg/l of astaxanthin but also accumulates astaxanthin biosynthesis intermediates, 5.7 mg/l canthaxanthin, and 35.3 mg/l echinenone. The copy numbers of crtZ and crtW are optimized to obtain 3.5 mg/g dry cell weight (54.6 mg/l) of astaxanthin in a microtiter plate cultivation Yarrowia lipolytica
