L-Phenylalanine Production by Stabilised Calcium Alginate Immobilised Aminoacylase

Enzymatic resolution of DL-amino acids using aminoacylase immobilised on DEAE-sephadex has been employed in the industry for the production of the optically active, L-amino acid There are,however, soeliitations to this technique. The aims of this study were to establish an efficient immobilisatio...
