The effect of incorporation of different proportions of trehalose dicorynomycolates (TDC) into lecithin bilayer membranes was studied. It was found that TDC, induces a 14% decrease of water osmotic permeability (42.6 +/- 3.9 to 36.8 +/- 2.7 microns/s) at 1.6 mole%, suggesting that this substance leads to an increase of the degree of packing of the constituent lipid molecules. A condensing effect of TDC was also apparent from membrane electrical capacitance (Cm) measurement. By incorporating TDC into bilayer membranes, the value of Cm experienced a decrease of 29% at 1.6% mole fraction. This finding was taken to reflect an increase in membrane thickness, known in many examples, to be related to the condensing effect.
