Nitrogenous Components of Phospholipids extracted from Penicillium chrysogenum

PREVIOUS work carried out on the lipids of Penicillium chrysogenum1,2 has implicated the phospholipids as important metabolic constituents of the mould. Subsequent analysis of these phospholipids on silicic acid impregnated paper indicated the presence of a number of compounds having RF values similar to those obtained by Marinetti et al.3 for phospholipids isolated from rat liver and heart tissue. Silberman and Gaby4 have identified the majority of nitrogenous compounds present in the aqueous fraction of the acid hydrolysate of phospholipids extracted from the Gram-negative bacillus Pseudomonas aeruginosa by two-dimensional chromatography as choline, leucine, valine or methionine, ethanolamine, alanine, threonine, lysine, glycine, glutamic acid, serine, cysteine and aspartic acid.
