'Microbial oleaginous host cell, oil, method of making an oil, method of increasing c18 to c20 elongation conversion efficiency in a recombinant oleaginous microbial host cell and method of increasing desaturation conversion efficiency (delta) 4 in a long chain polyunsaturated fatty acid-producing microbial recombinant oleaginous host cell '

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.
