In this communication, pure D- or L-glutamic acid crystals can be obtained from a racemic solution by controllable addition of chiral seed crystals and ultrasonic-assisted recrystallization. In contrast, only racemic compounds were yielded under identical conditions in bulk solutions in the absence of an ultrasonic field.
