摘要:
The present application relates to recombinant microorganisms useful in the biosynthesis of unsaturated C6-C24 fatty alcohols, aldehydes, and acetates which may be useful as insect pheromones, fragrances, flavors, and polymer intermediates. The C6-C24 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 C6-C24 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 provides methods by which trans-(1R,2S)-2-(3,4-difluorophenyl)-cyclopropylamine and related cyclopropane compounds are prepared using synthetic strategies that include a biocatalytic cyclopropanation step.
摘要:
The present application relates to methods to improve biomass or lipid production in a microorganism from one or more fatty acid and one or more simple carbon co-substrates. Produced lipids may include unsaturated C 6 -C 24 fatty acids, alcohols, aldehydes, and acetates which may be useful as final products or precursors to insect pheromones, fragrances, flavors, and polymer intermediates. The application further relates to recombinant microorganisms modified for improved production of biomass or lipid, or improved lipid selectivity. Also provided are methods of producing one or more lipid using the recombinant microorganisms, as well as compositions comprising the recombinant microorganisms and/or optionally one or more of the product lipid.
摘要:
and b) converting the metathesis product to the fatty olefin derivative. Each R1 is independently selected from H, C1-18 alkyl, and C2-18 alkenyl; R2b is C1-8 alkyl; subscript y is an integer ranging from 0 to 17; and subscript z is an integer ranging from 0 to 17. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is a pheromone. Pheromone compositions and methods of using them are also described.
