A phosphatidylinositol-containing derivative of Lactobacillus casei ATCC 7469.
A derivative of Lactobaccillus casei ATCC 7469, characterized by limited growth in liquid media and an unusual phospholipid composition, has been isolated. Grown to early stationary phase on a lipid-free and inositol-free medium, the organism produces phosphatidylinositol phosphatidylglycerol, and diphosphatidylglycerol. The phosphatidylinositol was identified by thin-layer, paper, and gas chromatography, and by mass spectrometry. In agreement with published data, the conventional strain produced phosphatidylglycerol, diphosphatidylglycerol, and lysylphosphatidylglycerol, but no phosphatidylinositol. The phospholipid/glycolipid molar ratio, calculated on the basis of published glycolipid analyses, is 1.3 : 1 for the derivative and 1.5 : 1 for the conventional strain.
