Mode opératoire

The amount of glucose fed was 2021 g over 52 hours. The fermentation medium included a D-, L-alanine feed whereby a total of 1400 mls of 167 g/l D-, L-alanine was fed at a rate of 1.9 ml/min starting 12 hrs from the beginning of the fermentation. In addition, L-phenylalanine was fed at the same concentration and rate as the D-, L-alanine. The fermentation resulted in 13.66 g/l of D-phenylalanine and 0.87 g/l L-phenylalanine being produced.
