| Abstrakt: |
The lytic effect of non-ionogenic surface active compounds (SAC), based on polyoxyethylated fatty acids and alkylphenols on the yeast protoplast cytoplasmic membranes and the extracting ability of the SAC with respect to intracellular proteins of intact yeast cells, were studied. It was shown that the lytic activity of the SAC under study depends on the overall effect of the size of their hydrophobic and hydrophylic fragments rather than on the level of the hydrophylic-lypolytic equilibrium of SAC. The absence of correlation between the lytic activity and the extracting ability of SAC is accounted for by the differences in the mechanisms of membrane degradation under the action of SAC on the protoplasts and intact cells. The data obtained support the previously made assumption that the correlation between the size of SAC mycelles and that of the cell wall pores is the limiting factor of the SAC induced protein extraction from the intact cells. |
