Abstract: Prodn. of enantiomeric lactams of formula (I) comprises reacting a racemate (I) with a biocatalyst which reacts with one enantiomer and isolating the unreacted enantiomer from the mixt. obtd. R1, R2 = 1-4C alkyl, 2-4C alkenyl or aryl (all opt. substd.), H or (CH2)n-COOH; n = 0-3; x = 1-5. Pref. the biocatalyst is a microorganism, esp. from Pseudomonas or Rhodococcus.

Abstract: Process for preparing a biocatalyst by mixing a) polyolefin fibres which have been rendered hydrophilic, b) crude porcine pancreatic lipase, c) at least one water-soluble dihydric to hexahydric alcohol with 2 to 6 carbon atoms and d) an aqueous buffer solution of pH 5 to 9 at 0 to 40 DEG C, filtering after 1 minute to 3 days, and washing the filter cake, and the use of the biocatalyst obtained in this way for resolving esters of racemic alcohols in aqueous medium.
