A method for the production of proteinogenic or non-proteinogenic L-amino acids, especially L-phosphinothricin, from their racemic N-acetyl-D,L-derivatives. The method is characterized in that: (a) N-acetyl-L-derivatives of the corresponding L-amino acids are selectively deacetylated by enzymatic racemate cleavage by means of isolated recombinant enzymes while the N-acetyl-D-derivatives of the corresponding D-amino acids are not deacetylated and (b) the deacetylated L-amino acids are preparatively separated from the non-deacetylated N-acetyl-D-derivatives and/or the incompletely deacetylated N-acetyl-L-derivatives. |
