Ultrafiltration experiments for the optical resolution of racemic phenylalanine were investigated in a DNA solution system and by using immobilized DNA membranes. L-phenylalanine preferentially existed in the permeate solution and D-phenylalanine preferentially existed in the concentrate solution in
