Lipid compositions in the stable L-form and the autoplast (protoplast made by autolysis) derived from Staphylococcus aureus 209P were studied in correlation to an adaptational change of the plasma membrane against the loss of cell wall.Cardiolipin content comprised over 50% of the total phospholipids (parent, 10%) both in L-form and autoplast, while phosphatidylglyceride, the precursor of cardiolipin, lowered the content to 30% (parent, 76%). The increase of cardiolipin was resulted clearly from the removal of cell wall. Cholesterol was found in stable L-form at the amount of 0.75% of total lipids. The synsthesis activity of cholesterol seemed to be expressed by the L-form transformation.The role of cardiolipin and cholesterol in a wall lacking cell was discussed in the light of adaptational changes in lipid composition of plasma membrane.
