Abstract
Eight components, seven of which contained phosphorus, were found in the phospholipid fraction of
Rhodomicrobium vannielii
. The major components were lipoamino acid (
o
-ornithine ester of phosphatidyl glycerol, 46.5%) and phosphatidyl choline (26.5%). The other six components were phosphatidyl glycerol (9.7%), bisphosphatidic acid (6.7%), phosphatidyl ethanolamine (4.5%), phosphatidic acid (1.8%), lysophosphatidyl glycerol-
o
-ornithine ester (3.2%), and
N,N
-ornithine amide of unidentified fatty acid (0.95%). Total phospholipid accounted for 4.2% of cell dry weight. The major fatty acid was vaccenic acid, C
18:1
, which accounted for approximately 90% of the total fatty acids of the complex lipid fraction. The other four fatty acids were C
16:0
(6.25%), C
18:0
(3.8%), C
14:0
(0.7%), and C
16:1
(0.35%). The sulfolipid content was 0.01% of the cell dry weight or 0.14 μmoles per g of dried cells, assuming that its fatty acid component is vaccenic acid. No steroids were detected.
