| Abstract: | The phospholipid and fatty acid composition of Alteromonas putrefaciens S29 (non-halophilic type) and A. haloplanktis S5B (halophilic type) was determined. Major phospholipids of both strains were the same when they were grown in media containing optimum salt concentrations. However, the fatty acid composition of phos-pholipids in strain S29 was remarkably different from that of strain S5B. Strain S29 contained iso-C15: 0 and eicosapentaenoic acid (20: 5) as constituent fatty acids of phospholipids and also contained sterol ester and wax as neutral lipids. In contrast, strain S5B did not contain branched and polyunsaturated fatty acids, and neither sterol ester nor wax were detected. |
