Figure Lengend Snippet: P. furiosus DSM3638 was grown under optimal conditions (TRM at 3 % w/v NaCl and pH 6.8 with 10 g L -1 elemental sulfur) at different temperatures (80, 85, 90, 98, and 103 °C). 98 °C represents the optimal growth temperature. Error bars represent the standard deviation calculated on three biological replicates. * indicates temperatures with significantly different core lipid compositions. (A) Total core lipid compositions under each temperature. (B) Influence of the temperature on GDGT relative proportions. GDGT (dark purple) corresponds to the summed GDGT, regardless of the cyclopentane ring content. (C) Influence of the temperature on GMGT relative proportions. GMGT (dark red) corresponds to the summed GMGT, regardless of the cyclopentane ring content. (D) Influence of the temperature on DGD relative abundance. (E) Influence of the temperature on GTGT0 relative abundance. (F) Temperature dependence of the ring index (RI) for all tetraethers (GDGT, GTGT, and GMGT), GDGT and GMGT (RI ± standard deviation). (G) Temperature dependence of the GMGT/GDGT ratio.
