A solid form of (−)-Ambrox formed by a bioconversion process.

The present invention relates to a biocatalytical method for manufacturing of homoeriodictyol dihydrochalcone and/or hesperetin dihydrochalcone by providing at least one first biocatalyst system for the hydroxylation of phloretin and/or its glycosides as well as at least one second biocatalyst for the methylation of 3-hydroxyphloretin. Further disclosed are microorganisms capable of producing such biocatalysts as well as sequences encoding the biocatalysts. Furthermore, the present invention relates to the use of a mixture obtained by a method as disclosed in the present invention and to specific compositions suitable as sweetness enhancers and/or flavouring agents.
