Reference strains of ‘ Pseudomonas diazotrophicus ’ produce a range of polar lipids atypical of authentic Pseudomonas species. In addition to the phospholipids common in Gram‐negative bacteria (phosphatidylglycerol, diphosphatidylglycerol, and phosphatidylethanolamine), N ‐methylated derivatives of phosphatidylethanolamine (including phosphatidylcholine) and an ornithine amide lipid are also present. The preponderant ester‐bound fatty acid (up to 80% of the total) is cis ‐vaccenic acid ( cis ‐octadec‐11‐enoic acid), while 3‐hydroxyoctadecanoic acid is the major amide‐bound fatty acid in the ornithine lipid. Possible implications of the data for classification of the organism are discussed.
