Abstract:
Methods to produce resveratrol and/or resveratrol glucoside in a recombinant oleaginous microorganism are provided. Expression of a resveratrol synthase gene in combination with genes involved in the phenylpropanoid pathway enabled recombinant microbial production of resveratrol in significant amounts.

Abstract:
A thermostable TAL enzyme was identified from the fungus Phanerochaete chrysosporium, which has high activity at temperatures of 40° C. to about 60° C. The enzyme was produced in engineered cells and used for production of para-hydroxycinnamic acid (pHCA) from tyrosine. When the pHCA production reaction was run at high temperature, the enzyme was more active and pHCA was produced more rapidly, making the reaction more efficient.

Abstract:
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. Production host cells are claimed, as are methods for producing EPA within said host cells.
Abstract:
Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding delta-9 elongases along with a method of making long-chain polyunsaturated fatty acids (PUFAs) using these delta-9 elongases in plants.
Abstract:
Engineered strains of the oleaginous yeast Yarrowia lipolytica capable of producing greater than 50 weight percent of eicosapentaenoic acid [“EPA”], an ω-3 polyunsaturated fatty acid, in the total oil fraction are described. These strains over-express heterologous Δ9 elongases, Δ8 desaturases, Δ5 desaturases, Δ17 desaturases, Δ12 desaturases and C16/18 elongases, and optionally over-express diacylglycerol cholinephosphotransferases. Preferred gene knockouts are described, as are methods for producing EPA within the host cells and products comprising EPA from the optimized Yarrowia lipolytica strains.
Abstract:
Engineered strains of the oleaginous yeast Yarrowia lipolytica are disclosed herein that are capable of producing microbial oil comprising greater than 25 weight percent of eicosapentaenoic acid [“EPA”], an omega-3 polyunsaturated fatty acid, measured as a weight percent of dry cell weight.
Abstract:
Coordinately regulated over-expression of the genes encoding glucose 6-phosphate dehydrogenase [“G6PDH”] and 6-phospho-gluconolactonase [“6PGL”] in transgenic strains of the oleaginous yeast, Yarrowia lipolytica, comprising a functional polyunsaturated fatty acid [“PUFA”] biosynthetic pathway, resulted in increased production of PUFAs and increased total lipid content in the Yarrowia cells. This is achieved by increased cellular availability of the reduced form of nicotinamide adenine dinucleotide phosphate [“NADPH”], an important reducing equivalent for reductive biosynthetic reactions, within the transgenic microorganism.
Abstract:
Isolated nucleic acid fragments and recombinant constructs comprising such fragments encoding delta-8 desaturases along with a method of making long-chain polyunsaturated fatty acids (PUFAs) using these delta-8 desaturases in plants and oleaginous yeast.
