Inhibitory influences of high concentrated salt solutions and organic acids on L-glutamic acid decarboxylase in aquash were tested. Final concentrations of sodium chloride more than 1 per cent in the enzymic procedure lead to the decrease of the quantitative value of L-glutamic acid (Fig. 1). Copper sulfate showed an inhibiting influence at its final concentration of 0.1 per cent on the enzymic reaction mixture. In the case of some organic acids, such as acetic, propionic and butyric acid, the inhibition was remarkable, but lactic aicd was less inhibiting. The more hydroxyl group in the molecule of the orgaic acids, such as succinic, malic and tartarie acid, the less inhibiting effects on the L-glutamic acid decarboxylase were recognized.
