    Abstract: The present disclosure relates to chemo-enzymatic processes for the preparation of lactones (including, e.g., macrolactones, γ-lactones, and δ-lactones) and/or macrocyclic ketones, which are compounds of industrial value, for example, for use as fragrance ingredients. The chemo-enzymatic processes combine the in vivo microbial production of fatty acid derivatives and the subsequent ex vivo synthetic transformation of the fatty acid derivatives to provide the lactones and macrocyclic ketones.

    Abstract: The invention provides polypeptides and encoding nucleic acids of aldehyde dehydrogenase variants. The invention also provides cells expressing aldehyde dehydrogenase variants. The invention further provides methods for producing 3-hydroxybutyraldehyde (3-HBal) and/or 1,3-butanediol (1,3-BDO), or an ester or amide thereof, comprising culturing cells expressing an aldehyde dehydrogenase variant or using lysates of such cells. The invention additional provides methods for producing 4-hydroxybutyraldehyde (4-HBal) and/or 1,4-butanediol (1,4-BDO), or an ester or amide thereof, comprising culturing cells expressing an aldehyde dehydrogenase variant or using lysates of such cells.
