A method for the in vivo bioconversion of cyclic carotenes having a β-ionone ring to the corresponding aryl carotene is provided. Gram negative host cells expressing a heterologous, codon-optimized gene encoding a carotene desaturase are grown in the presence of a suitable cyclic carotene substrate to effect the production of aromatic carotenoids.
A method for the production of aryl-carotenoids is provided through bioconversion of cyclic carotenoids having at least one β-ionone ring. Expression of a heterologous gene encoding a carotene desaturase (crtU) enzyme in a host cell that produces a suitable cyclic carotenoid substrate effect the production of aryl carotenoids.
