[Enzymatic hydrolysis of fat in the presence of Lamblia duodenalis (in vitro)].

The influence of Lamblia on the hydrolysis of fat by lipase was studied in vitro. The hydrolysis rate of fat in the presence of live Lamblia and without them was determined colorimetrically by the quantity of the formed glycerine. In addition, the kinetics of this reaction was studied by the method of compensating potentiometry by neutralization of fat acids with alkali. The intact organisms were found to cause an inhibition of fermentative hydrolysis of fat. The importance of this fact from the point of view of interaction in the host-parasite system is discussed.
