摘要:
According to the present invention, by using a microorganism having the ability to produce the L-amino acid which carries the avt A gene encoding alanine-valine transaminase (transaminase C) and whose alanine-valine transaminase activity is enhanced compared with its parent strain, it is possible to reduce the production of by-product amino acids which disturb purification in L-amino acid production by fermentation, and an industrially advantageous process for producing an L-amino acid can be provided.
