Recombinant production of carotenoids, particularly astaxanthin

摘要

The present invention is directed to a process for producing carotenoids comprising cultivating a recombinant organism having a gene for one or more active oxygen species-quenching factor(s) that is substantially disrupted with a disruption cassette specific to the gene, and recovering carotenoids from the culture, as well as to genetic materials useful in the said process, such as a recombinant organism producible of carotenoids, a disruption cassette, a recombinant DNA sequence, a recombinant DNA fragment; and a polynucleotide.
