One of the enantiomers of an acid is prepared by a process in which enantioselective hydrolysis of a mixture of the corresponding R and S amide is carried out in the presence of an enzymatically active biological material having enantioselective amidase activity, the biological material being derived from a strain of Rhodococcus, Serratia, Moraxella or Pseudomonas. |
