Engineered strains of the oleaginous yeast yarrowia lipolytica capable of producing greater than 25% eicosapentaenoic acid (epa, an ω-3 polyunsaturated fatty acid) in the total oil fraction are described. These strains comprise various chimeric genes expressing heterologous desaturases, elongases and acyltransferases and optionally comprise various native desaturase and acyltransferase knockouts to enable synthesis and high accumulation of epa.

 Process for separation of renewable materials from m icroorganisms patent thumbnailProcess for separation of renewable materials from m icroorganisms
Methods of separating renewable materials, such as lipids, from microorganisms, such as oleaginous yeasts, may include conditioning cell walls of the microorganisms to form, open or enlarge pores, and removing at least a portion of the renewable material through the pores. These methods may result in delipidated microorganisms with cell walls that are substantially intact and with mesopores.

 Mutant acyl-coa:lysophosphatidylcholine acyltransferases patent thumbnailMutant acyl-coa:lysophosphatidylcholine acyltransferases
Mutant acyl-coa:lysophosphatidylcholine acyltransferases [“lpcats”] having the ability to convert acyl-coa+1-acyl-sn-glycero-3-phosphocholine to coa+1,2-diacyl-sn-glycero-3-phosphocholine (ec 2.3.1.23) are disclosed herein. Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding mutant lpcats, along with a method of making long chain polyunsaturated fatty acids [“pufas”] using these mutant lpcats in oleaginous yeast, are also disclosed..

Renewable chemicals and fuels from oleaginous yeast


The invention provides methods of cultivating oil-bearing microbes using xylose alone or in combination with other depolymerized cellulosic material. Also provided are microorganisms comprising an exogenous gene encoding a polysaccharide degrading enzyme, such as a cellulase, a hemicellulase, a pectinase, or a driselase.

Process for the production of lipids from biomass


Process for the production of lipids from biomass comprising polysaccharides. The biomass is subjected to acid hydrolysis to obtain a solid phase and an aqueous phase.

Production of polyunsaturated fatty acids in oleaginous yeasts


The present invention relates to methods for the production of ω-3 and/or ω-6 fatty acids in oleaginous yeast. Thus, desaturases and elongases able to catalyze the conversion of linoleic acid (la) to γ-linolenic acid (gla); α-linoleic acid (ala) to stearidonic acid (sta); gla to dihomo-γ-linoleic acid (dgla); sta to eicosatetraenoic acid (eta); dgla to arachidonic acid (ara); eta to eicosapentaenoic acid (epa); dgla to eta; epa to docosapentaenoic acid (dpa); and ara to epa have been introduced into the genome of yarrowia for synthesis of ara and epa..
