The influence of rape‐oil as antifoam agent on growth and protease synthesis of T. vulgaris was studied. The turbulence and the aeration conditions caused by the culture vessel have a fundamental importance for the so‐called oil effect. A higher aeration rate induces an enhanced lysis of the mycelium and consequently a reduced enzyme synthesis. The tentency to lysis of the mycelium at different selectants is variable. The addition of oil to the culture medium reduces this tendency and promotes the protease production. The oil effect on the enzyme synthesis is higher in deficient medium than in full one.
