Redundant oil microbial cells for the production of modified Eicosapensenoico acid are used to code an active calcium phosphate soluble polyurethane for the production of oil containing this long-chain fatty acid.

摘要

Methods for increasing C18 to C20 elongation conversion efficiency and/or ?4 desaturation conversion efficiency in long-chain polyunsaturated fatty acid ["LC-PUFA"]-producing recombinant oleaginous microbial host cells are provided herein, based on over-expression of acyl-CoA:lysophospholipid acyltransferases ["LPLATs"] (e.g., AIe1, LPAAT, LPCAT). Production host cells and oils produced by the methods of the invention are also claimed.
