A process for preparation of (R)- aromatic α-hydroxy ketones of formula (I), said process occurring in strain(s) of yeast expressing a recombinant pyruvate decarboxylase, having cysteine residues at positions 221 and 222 of PDC1, an isoenzyme of said pyruvate decarboxylase, substituted with glutamate and alanine respectively such that the said mutation being in the regulatory site of pyruvate decarboxylase, selectively favours carboligation reaction over decarboxylation. |
