Abstract:
Fuels and other valuable compositions and compounds can be made from oil extracted from microbial biomass and from oil-bearing microbial biomass via hydroprocessing and/or other chemical treatments, including the alkaline hydrolysis of glycerolipids and fatty acid esters to fatty acid salts.
Abstract:
Provided are methods for preparing chemically modified lipids. The lipids are obtained from heterotrophically cultured microalgae and are subjected to an epoxidation reaction. The microalgae include those from the genus Parachlorella, Prototheca, Chlorella, or strains having at least 85% nucleotide sequence identity in 23S rRNA sequences to a Parachlorella, Prototheca, or Chlorella strain that are cultured in a bioreactor substantially in the absence of light.
Abstract:
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, 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.
