ABSTRACT:
The present invention provides a process for producing an L-amino acid which comprises culturing in a nutrient medium a microorganism which is capable of producing the L-amino acid and which can not grow in a synthetic medium containing said L-amino acid as the sole nitrogen source in an amount of 5 mg/ml or below, allowing the L-amino acid to accumulate in the culture, and recovering the L-amino acid from the culture.
