| Abstract: | The surface of silica gels was modified by an diethylamino group and an hydroxygroup, simultaneously. The activity of the aminoacylase immobilized on such amino-hydroxy-silica gels was 316.8 U/g. By its catalysis, the conversions of tested N-acetyl-D,L-amino acids toL-amino acids were 85%. |
