ABSTRACT:
A method for producing L-threonine by fermentation which comprises culturing in a culture medium a microorganism of the genus Brevibacterium or Corynebacterium which is resistant to mycophenolic acid and is capable of producing L-threonine, accumulating L-threonine in the medium, and then recovering the L-threonine accumulated therein.
