Based on the CSRD obtained by AMS the contribution of fossil OC (F14C=0; [%]) used for bacterial membrane lipid synthesis (IPL-FA) was calculated using an isotope mass balance. For the estimation two endmembers were used: 1) Fossil carbon (F14C=0) – OC derived from the local bedrock 2) Recently synt...
