ABSTRACT:
A process for producing L-leucine, which includes incubating an L-leucine-productive microorganism belonging to the genus Corynebacterium, Escherichia, Brevibacterium, or Microbacterium in a culture medium and reacting the resulting cells with saccharides and acetic acid or its salt to form and accumulate L-leucine in the reaction solution. The process improves the amount of L-leucine accumulated and decreases formation of amino acid byproducts.
