Some factors affecting the L-asparaginase activity of E. aroideae were investigated. Increasing concentrations of glucose in the culture medium had an inhibiting effect on the production of L-asparaginase by this microorganism. Buffering of the culture medium in order to stabilize the pH during growth resulted in a decrease of the L-asparaginase activity. From the different nitrogen sources examined, tryptone, proteose peptone nr 2 and nr 3 stimulated the L-asparaginase production. Toluene treatment of the cells practically destroyed the L-asparaginase. Acetone dried cells showed an L-asparaginase activity comparable with the activity of living cells.
