Hydrochloric Acid → L-Alanine

Participants

Reaction Steps

The treatment of one solution at 6% of hydrochloride of α-aminopropionamide in water (pH included between 6.5 to 8.5) can be effected by a suspension of cells of strain A4 at 20 to 40 g of dry matter per liter. Quantitatively L-α-alanine (50%) and D-α-aminopropionamide (50%) is obtained. This amide D can either be hydrolized in D-α-alanine by action of strain R 312 (CBS 717.73) or racemized and recycled with a view to the preparation of L-α-alanine.
