Patent
Provided herein compositions and methods for producing isoprenoids, including squalene. In certain aspects and embodiments provided are genetically converted yeast and uses therefore. In some aspects and embodiments, the genetically converted yeast produce isoprenoids, preferably squalene. Also are provided methods of producing squalene using a genetically converted yeast or a non-genetically converted yeast. The invention also provides squalene produced by genetically converted yeast or non-genetically converted yeast.
1. A composition comprising:
a yeast Yarrowia lipolytica strain selected from the group consisting of ATCC 20688, A TCC 90811, A TCC 90904, ATCC 90812, ATCC MYA-2613, or Yeastern polg that is genetically modified to overexpress the 457 amino-acid C-terminal catalytic domain of the hydroxymethylglutaryl CoA reductase from Yarrowia lipolytica encoded by the HMG1 gene.
