The lytic action of homologous series of sodium alkyl sulfates on yeast protoplasts was studied. The concentration dependences study allowed to estimate the lytic concentrations C50 of the agents required for the 50% lysis of protoplasts in the suspension. The data concerning the agents micelle formation in the lytic medium allowed to make some suggestions and to produce a model of the lytic action of alkyl sulfates on the plasma membrane of the protoplasts. The amounts of the agents absorbed on the membrane and involved in the interaction followed by the membrane breakdown in the model are evaluated. On the basis of the data obtained it is concluded that sodium dodecyl sulfate displays the highest lytic activity to the yeast protoplast plasma membrane as compared to the other alkyl sulfates used in the study. The results obtained are discussed in terms of the effect of yeast cell wall on the extraction of intracellular proteins from intact yeast cell under sodium alkyl sulfates action.
