A process for preparing D-lysine using a microorganism which has the ability to asymmetrically degrade L-lysine in a reaction medium is disclosed. The process is performed by first bringing racemic lysine into contact with a culture or a treated culture of the microorganism, and then collecting and isolating the D-lysine from the reaction mixture.
