MICRO-ORGANISMS OF KLEBSIELA STRAIN AND PROCESS OF MICROBIOLOGICAL PRODUCTION OF S-ALPHA-AMINOCARBOXYLIC ACIDS AND AMIDES OF R-ALPHA-AMINOCARBOXYLIC ACIDS
Microorganisms capable of (a) utilising racemic or optically active cyclic alpha -amino acid amides of formula (I) as their sole N source and (b) converting (RS)- alpha -amino acid amides of formula (I) to (S)- alpha -amino acids of formula (II) are new.

Summary: | Microorganisms capable of (a) utilising racemic or optically active cyclic alpha -amino acid amides of formula (I) as their sole N source and (b) converting (RS)- alpha -amino acid amides of formula (I) to (S)- alpha -amino acids of formula (II) are new. A = an opt. substd. 5- or 6-membered satd. ring. Also claimed is a process for preparing (S)- alpha -amino acids of formula (II) and/or (R)- alpha -amino acid amides of formula (III) from (RS)- alpha -amino acid amides of formula (I), in which the (S)-amide component of (I) is converted to the (S)-acid using a microorganism as above or a cell-free enzyme extract of such a microorganism and the (S)-acid is isolated and the unconverted (R)-amide is opt. isolated. |
