Geranyl acetate is, as one of the monoterpenoids, a natural constituent of more than 60 essential oils. Production of such an ester fragrance compound by plant extracts is limited by low yield and high processing costs but plausible by microbial synthesis. We report a microbial cell factory that realizes selective and high-level geranyl acetate production in Escherichia coli. For this purpose, co-expression of geraniol synthase and alc. acetyltransferase was initially used to increase production yield, but a considerable quantity of precursor geraniol was also produced. Further, introducing an extra AAT gene copy and controlling the substrate glycerol supply enabled a drastically higher selective geranyl acetate production Eventually, the highest reported titer of 52.78 mM (equivalent to 10.36 g/L) geranyl acetate, accounting for 98.5% of total products, was achieved under a controlled fermentation system. Such selective and high-level geranyl acetate production by combining genetic and bioprocess engineering is also a promising strategy for other monoterpene esters in E. coli. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Related Products of 367-93-1).
(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Related Products of 367-93-1
