Abstract
The production of carotenoid is accomplished using a DNA molecule that encodes a polypeptide as obtained from Haematococcus pluvialis, Phaffia rhodozyma, or Saccharomyces cerevisiae, having isopentonyl pyrophosphate (IPP) isomerase activity, or DNA molecule having a nucleotide sequence that hybridizes thereto. In particular, one can introduce such a DNA molecule into a carotenoid-producing microorganism, culture the microorganism thus transformed, and then obtain carotenoids in the culture broth and cells.
