Method of preparing D- alpha -amino acids |
摘要 |
A substantial elevation of the space-time yield is achieved in the preparation of D- alpha -amino acids by means of the biotransformation of hydantoins which are monosubstituted in the 5-position in an aqueous medium in the presence of cells of the microorganism Agrobacterium radiobacter if the biotransformation is carried out under a elevated pressure at the start of the reaction. A further improvement results if this elevated pressure is maintained for a period of at least 16 hours, then removed and the biotransformation continued at atmospheric pressure.
