Patent number: 10287613Abstract: Recombinant DNA techniques are used to produce oleaginous recombinant cells that produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Genes manipulated include those encoding stearoyl-ACP desturase, delta 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl-ACP synthase, and lysophosphatidic acid acyltransferase. The oil produced can have enhanced oxidative or thermal stability, or can be useful as a frying oil, shortening, roll-in shortening, tempering fat, cocoa butter replacement, as a lubricant, or as a feedstock for various chemical processes. The fatty acid profile can be enriched in midchain profiles or the oil can be enriched in triglycerides of the saturated-unsaturated-saturated type.Type: GrantFiled: January 19, 2018Date of Patent: May 14, 2019Assignee: CORBION BIOTECH, INC.Inventors: Scott Franklin, Aravind Somanchi, George N.

Patent number: 10125382Abstract: Novel plant acyl-ACP thioesterase genes of the FatB and FatA classes and proteins encoded by these genes are disclosed. The genes are useful for constructing recombinant host cells having altered fatty acid profiles. Expression of the novel and/or mutated FATB and FATA genes is demonstrated in oleaginous microalga host cells. Furthermore, a method for producing an oil elevated in one or more of C12:0, C14:0, C16:0, C18:0 and/or C18:1 fatty acids includes transforming a cell with novel and/or mutated FATB and/or FATA genes, e.g., having an N-terminal deletion. The cells produce triglycerides with altered and useful fatty acid profiles.Type: GrantFiled: September 18, 2015Date of Patent: November 13, 2018Assignee: CORBION BIOTECH, INC.Inventors: Jason Casolari, George N.
