Described herein is a biochemically produced sandalwood oil including at least 85% santalol and bergamotol and 1% or less cis-lanceol, where the oil has one or more of the following features: i) 5% or less alpha-santalal; ii) 5% or less farnesol; and iii) 0.5% or less spirosantalol. Also described herein are a perfuming composition including the sandalwood oil and a perfuming consumer product including the sandalwood oil. Also described herein are a method of using the biochemically produced sandalwood oil as an anti-microbial and anti-inflammatory agent, and an arthropod control composition including the sandalwood oil.

Biochemically produced sandalwood oil

Described herein are novel methods for the acetyl transferase-catalyzed production of drimanyl-acetate compounds by the acetylation of the respective drimanyl alcohol sources performed in vitro or in vivo. Also described herein is the identification of enzymes having corresponding acetyl transferase activity from different microbial and plant sources. Also described herein is the provision of enzyme mutants derived from the newly identified enzymes. Further described herein is the provision of corresponding coding sequences of such enzymes and mutants, recombinant vectors, and recombinant host cells suitable for the production of such acetyl transferases and mutants and for performing the novel production methods of drimanyl acetate compounds. Still further described herein is a method of using such drimanyl acetates as intermediates for the production of odorant, flavor or fragrance or insect/pest control ingredients.

Method for producing drimanyl acetate compounds

This invention relates generally to methods and compositions for producing a sesquiterpene alcohol comprising contacting a sesquiterpene with a P450 polypeptide with monooxygenase activity.

Method for producing fragrant alcohols

Described herein are methods of producing (+)-manool, the methods including: contacting geranylgeranyl diphosphate with a copalyl diphosphate (CPP) synthase to form a (9S, 10S)-copalyl diphosphate and contacting the CPP with a sclareol synthase enzyme to form (+)-manool and derivatives thereof. Also described herein are nucleic acids encoding CPP synthases and sclareol synthases for use in the methods. Further described herein are expression vectors and non-human host organisms and cells including nucleic acids encoding a CPP synthase and a sclareol synthase as described herein.

Production of manool

The present invention relates to a method of producing drimenol and/or drimenol derivatives by contacting at least one polypeptide with farnesyl diphosphate. The method may be performed in vitro or in vivo. The present invention also provides amino acid sequences of polypeptides useful in the method of the invention and nucleic acid encoding the polypeptides of the invention. The method further provides host cells or organisms genetically modified to express the polypeptides of the invention and useful to produce drimenol and/or drimenol derivatives.

Drimenol synthases I

This invention relates generally to methods and compositions for producing a sesquiterpene alcohol comprising contacting a sesquiterpene with a p450 polypeptide with monooxygenase activity.

The present invention relates to the control of gene expression by a heterologous glucose-regulated promoter, to microorganisms in which gene expression is controlled by a heterologous glucose-regulated promoter and to methods using said microorganisms for the production of terpenes during glucose-limited fed-batch fermentation.

Modified microorganisms and use thereof for terpene production

The present invention relates to yeast cells producing high levels of acetoacetyl-CoA. It also relates to a method for making such yeast cells and to the use of such yeast cells in a method for producing acetyl-CoA derived products.
