Summary Resting cells ofArthrobacter sp. (DSM 3745) with the ability to form L-tryptophan from D,L-5-(3-indolylmethy)hydantoin were used for the bioconversion of D,L-5-α- and D,L-5-β-naphthylmethylhydantoin (D,L-5-α- and D,L-5-β-NMH) to the corresponding L-amino acids. Under the optimal reaction conditions of pH 9.7 and 40°C specific productivities of 0.2 (α-naphtylalanine) and 0.6 (β-naphtylalanine) mM amino acid x g cell dry mass−1 x h−1 were obtained in a 0.1 M Na2CO3/NaHCO3-buffer in a strirred bioreactor.
