The present application relates to recombinant microorganisms useful in the biosynthesis of unsaturated C.sub.6-C.sub.24 fatty alcohols, aldehydes, and acetates which may be useful as insect pheromones, fragrances, flavors, and polymer intermediates. The C.sub.6-C.sub.24 fatty alcohols, aldehydes, and acetates described herein may be used as substrates for metathesis reactions to expand the repertoire of target compounds and pheromones. The application further relates to recombinant microorganisms co-expressing a pheromone pathway and a pathway for the production of a toxic protein, peptide, oligonucleotide, or small molecule suitable for use in an attract-and-kill pest control approach. Also provided are methods of producing unsaturated C.sub.6-C.sub.24 fatty alcohols, aldehydes, and acetates using the recombinant microorganisms, as well as compositions comprising the recombinant microorganisms and/or optionally one or more of the product alcohols, aldehydes, or acetates.

The present invention discloses an engineering yeast strain for producing nervonic acids. The yeast strain over-expresses the genes related to enzymes required in a synthetic process of long-chain unsaturated fatty acids, such as fatty acid elongase, desaturase, diacylglycerol acyltransferase and the like, and optionally, further adjusts and controls the synthesis and decomposition route of triglyceride, the synthesis and decomposition route of sphingomyelin, and the synthesis and decomposition route and the oxidation-reduction balanced route of lipid subcell levels. The recombinant yeast strain can produce microorganism oil; and the content of the prepared nervonic acids accounts for 39.6% of the total fatty acids.

The current methods and compositions provide for nucleotide sequences of promoters from Yarrowia lipolytica which may be used to drive gene expression in a cell. In some aspects, the promoters are useful for modulating lipid production in oleaginous organisms such as yeast.

Disclosed are nucleotide sequences and corresponding amino acid sequences of Arxula adeninivorans genes that can be utilized to manipulate the lipid content and/or composition of a cell. Methods and compositions for utilizing this information are disclosed to increase the lipid content or modify the lipid composition of a cell by either increasing or decreasing the activity of certain genetic targets.

The present disclosure features methods and compositions for modulating lipid metabolism to achieve improved production and quality of recombinant products, such as next generation biologics. Modulation of lipid metabolism as described herein includes, for example, introducing a lipid metabolism modulator described herein to a cell or a cell-free system. Also encompassed by the present disclosure are engineered cells with improved production capacity and improved product quality, methods for engineering such cells, and preparations and mixtures comprising the products from such cells.
