| 中文摘要 | here we reported the fatty-acids and their delta c-13 values in seep carbonates collected from green canyon lease block 185 (gc 185; sample gc-f) at upper continental slope (water depth:similar to 540 m), and alaminos canyon lease block 645 (gc 645; sample ac-e) at lower continental slope (water depth: similar to 2200 m) of the gulf of mexico. more than thirty kinds of fatty acids were detected in both samples. these fatty acids are maximized at c-16. there is a clear even-over-odd carbon number predominance in carbon number range. the fatty acids are mainly composed of n-fatty acids, iso-/anteiso-fatty acids and terminally branched odd-numbered fatty acids (iso/anteiso). the low delta c-13 values (-39.99aeuro degrees to.32.36aeuro degrees) of n-c-12:0, n-c-13:0, i-c-14:0 and n-c-14:0 suggest that they may relate to the chemosynthetic communities at seep sites. the unsaturated fatty acids n-c-18:2 and c-18:1 delta(9) have the same delta c-13 values, they may originate from the beggiatoa/thioploca. unlike other fatty acids, the terminally branched fatty acids (iso/anteiso) show lower delta c-13 values (as low as -63.95aeuro degrees) suggesting a possible relationship to sulfate reducing bacteria, which is common during anaerobic oxidation of methane at seep sites. |
