synthesis | synthesis of astaxanthin. Astaxanthin is a carotenoid of significant commercial value due to its superior antioxidant potential and wide applications in the aquaculture, food, cosmetic and pharmaceutical industries. The Brevundimonas sp. SD212 crtW and Pantoea ananatis crtZ genes are the best combination for astaxanthin production. After balancing the activities of beta-carotene ketolase and hydroxylase, an Escherichia coli ASTA-1 that carries neither a plasmid nor an antibiotic marker is constructed to produce astaxanthin as the predominant carotenoid (96.6%) with a specific content of 7.4/g dry cell weight without an addition of inducer | Brevundimonas sp. NBRC 101024 |
