ABSTRACT:
The present invention provides a method for producing a dipeptide from starting materials that are available at low costs through a route industrially advantageous and simple. Dipeptides are produced from amino acid esters and amino acids by using a culture of a microbe having an ability to produce a dipeptide from an amino acid ester and an amino acid, microbial cells separated from the culture, or treated microbial cell product.
