Fig. 5From: High cell density production of multimethyl-branched long-chain esters in Escherichia coli and determination of their physicochemical propertiesDifferential scanning calorimetry (DSC). DSC measures changes in heat flowing through the sample as the oil is heated or cooled between solid and liquid phases. P-DSC measures changes in heat flowing through the sample as it is heated under a constant flow of oxygen as purge gas. a Cooling (top) and melting (bottom) transitions of the MBE measured by DSC. Transitions were characterized by the onset temperatures annotated next the cooling (−9.61 °C) and heating (−6.82 °C) scans in the figure. Refer to Table 3 for transition temperatures. b Onset temperature (187.65 °C) obtained for the onset of thermo-oxidative degradation measured by P-DSC for the MBE sample.
