| 1 | Method For Producing Carotenoids Each Having 50 Carbon Atoms | US15384420 | 2016-12-20 | US20170191103A1 | 2017-07-06 | Daisuke Umeno; Maiko Furubayashi; Norihiko Misawa; Shinichi Takaichi |
| The present invention provides a method of producing a carotenoid having 50 carbon atoms which comprises culturing, in a medium, a cell transformed with a mutant phytoene desaturase gene and obtaining the carotenoid having 50 carbon atoms from the culture. The mutant phytoene desaturase gene has an introduced mutation to encode a mutant phytoene desaturase having an enhanced activity to desaturate a carotenoid backbone compound of 50 carbon atoms. | ||||||
