  • Process for producing L-2-aminoadipic acid
    Patent number: 5906927
    Abstract: A process for producing L-2-aminoadipic acid, which comprises converting an aminomethyl group of L-lysine into a carboxyl group by use of a culture of a microorganism of the genus Flavobacterium. By this process, L-2-aminoadipic acid can be obtained directly from L-lysine in a high yield. This process is a microbial method which is effective for the mass production.
