The present invention provides a method of producing (−)-rotundone from α-guaiene. The method includes the steps of: (1) allowing a cytochrome P450 protein to act on α-guaiene, which cytochrome P450 belongs to the CYP152 family and is capable of oxidizing the methylene group at position 3 of α-guaiene to the carbonyl group; and/or (2) allowing a cytochrome P450 protein to act on α-guaiene in the presence of an electron transfer protein capable of transferring electrons to the cytochrome P450 protein, which cytochrome P450 belongs to the CYP152, CYP106, or CYP107 family and is capable of oxidizing the methylene group at position 3 of α-guaiene to the carbonyl group.

A liquid detergent composition, preferably a liquid manual dishwashing detergent composition, comprising one or more hydroperoxy fatty acid producing enzymes selected from the group consisting of: arachidonate lipoxygenases, alpha-dioxygenases, and mixtures thereof, preferably alpha-dioxygenases, a surfactant system and a liquid carrier (i.e., water). Methods of washing comprising the liquid detergent composition are also provided.

A detergent composition, preferably a manual dishwashing detergent composition, including one or more diol synthases capable of converting one or more unsaturated fatty acids into one or more oxylipins, and a surfactant system including one or more anionic surfactants and one or more co-surfactants selected from the group consisting of amphoteric surfactant, zwitterionic surfactant, and mixtures thereof. Method of using the detergent composition including a surfactant system and the diol synthases are also provided.

The present invention provides a method of producing ()-rotundone from -guaiene. The method includes the steps of: (1) allowing a cytochrome P450 protein to act on -guaiene, which cytochrome P450 belongs to the CYP152 family and is capable of oxidizing the methylene group at position 3 of -guaiene to the carbonyl group; and/or (2) allowing a cytochrome P450 protein to act on -guaiene in the presence of an electron transfer protein capable of transferring electrons to the cytochrome P450 protein, which cytochrome P450 belongs to the CYP152, CYP106, or CYP107 family and is capable of oxidizing the methylene group at position 3 of -guaiene to the carbonyl group.

A detergent composition, preferably a manual dishwashing detergent composition, including one or more diol synthases capable of converting one or more unsaturated fatty acids into one or more oxylipins, and a surfactant system including one or more anionic surfactants and one or more co-surfactants selected from the group consisting of amphoteric surfactant, zwitterionic surfactant, and mixtures thereof. Method of using the detergent composition including a surfactant system and the diol synthases are also provided.

A liquid detergent composition, preferably a liquid manual dishwashing detergent composition, comprising one or more hydroperoxy fatty acid producing enzymes selected from the group consisting of: arachidonate lipoxygenases, alpha-dioxygenases, and mixtures thereof, preferably alpha-dioxygenases, a surfactant system and a liquid carrier (i.e., water). Methods of washing comprising the liquid detergent composition are also provided.

A surfactant containing detergent composition, preferably a manual dishwashing detergent composition, comprising either a combination of one or more hydroperoxy fatty acid producing enzymes and one or more hydroperoxy fatty acid converting enzymes, or at least one fatty acid processing fusion enzyme comprising at least two catalytic domains: a hydroperoxy fatty acid producing domain and a hydroperoxy fatty acid converting, and methods of using such compositions.

There is provided a method of producing at least one unsaturated amino acid from at least one amino acid comprising at least two carbonyl groups, the method comprising (a) contacting a recombinant microbial cell with a medium comprising the amino acid comprising the carbonyl groups, wherein the cell is genetically modified to compriseat least a first genetic mutation that increases the expression relative to the wild type cell of an enzyme (E) selected from the CYP152 10 peroxygenase family, andat least a second genetic mutation that increases the expression relative to the wild type cell of at least one NAD(P)+ oxidoreductase (E2) and the corresponding mediator protein.

The present invention provides a microbial cell capable of producing at least one terminal alkene from at least one short chain fatty acid, wherein the cell is genetically modified to comprise at least a first genetic mutation that increases the expression relative to the wild type cell of an enzyme (E.sub.1) selected from the CYP152 peroxygenase family, and at least a second genetic mutation that increases the expression relative to the wild type cell of at least one NAD(P)+ oxidoreductase (E.sub.2) and the corresponding mediator protein, wherein the short chain fatty acid is a C4-C10 fatty acid.
