(Fig. 1) Bacterial intact polar lipids and Archaeal intact polar lipids in the time zero sample and incubationsis from ODP Hole 204-1245D

Results are from one single measurement except for the time-zero values, which are the average of duplicate measurements. The 13C-labeled phospholipids originally present in S. platensis, distinguishable from their distinct mass intensities and fragmentation in HPLC-MS analysis, were not included for quantification.
