Recombinant microalgae including keto-acyl ACP synthase
First Claim
1. A process for producing a triglyceride oil from a microalgae, the process comprising:
- (i) cultivating a recombinant oleaginous microalgal cell comprising exogenous nucleic acids encoding a KAS (keto-acyl ACP synthase) or wherein nucleic acids encoding an endogenous KAS are disrupted by homologous recombination to produce said triglyceride oil; and
(ii) isolating said triglyceride oil from said recombinant oleaginous microalgal cell,wherein said triglyceride oil has a fatty acid profile that is at least 40% saturated fatty acids, and said fatty acid profile of said triglyceride oil comprises at least;
10% C8;
0, 20% C10;
0, 50% C12;
0, 40% C14;
0, 60% C16;
0, or 30% C18;

Abstract
Methods and compositions for the production of food compositions, oils, fuels, oleochemicals, and other compounds in recombinant microorganisms are provided, including oil-bearing microorganisms and methods of low cost cultivation of such microorganisms. Microalgal cells containing exogenous genes encoding, for example, a lipase, a sucrose transporter, a sucrose invertase, a fructokinase, a polysaccharide-degrading enzyme, a keto acyl-ACP synthase enzyme, a fatty acyl-ACP thioesterase, a fatty acyl-CoA/aldehyde reductase, a fatty acyl-CoA reductase, a fatty aldehyde reductase, a fatty aldehyde decarbonylase, and/or an acyl carrier protein are useful in manufacturing food compositions, and transportation fuels such as renewable diesel, biodiesel, and renewable jet fuel, as well as oleochemicals such as functional fluids, surfactants, soaps and lubricants.
