1 ml mineral (paraffin) oil barrier Protein Tyrosine Kinase inhibitor is clearly penetrated by oxygen (present in the unfilled 0.4 ml headspace of the cell). The best decomposition of this extended (≈ 60 hours) experiment actually involves 3 peaks: the first one clearly pertains to “dissolved oxygen” growth; the second accounts for “mineral (paraffin) oil hindered

diffused oxygen” growth; the third may be due to a fully fermentative growth switch of (some fraction of) the bacterial population. Variations of total and peak thermal effects “Thermal growths” associated to overall thermograms (total thermal growths) and to the corresponding components (peak or process thermal growth) were further analyzed. Total growth heats expressed as specific values (in J/ml suspension), or absolute values (in J) were calculated from raw thermograms in Calisto. The corresponding peak (growth process) values are simply obtained by multiplication with the a 0 Peakfit parameter, which equals its (area) fraction to the overall effect. Variations of the heat effects with available air volume are presented

in Figure  7, as follows: 7a average values for E. coli runs analyzed in Section B; 7b average values for S. aureus runs analyzed in Section B; 7c E. coli physiological saline dilution runs. As in Figure  3, specific total and peak heats (J/ml suspension) that HM781-36B chemical structure display a non-linear variation with cell headspace air volume were fitted with exponentials. Average values were used in Figure  7a and b, whereas values for all runs HMPL-504 are given in Figure  3: therefore, slight differences of the fitting parameters may be noticed. Absolute total and peak heats (J) display fairly linear variations with air volume (with better correlation for E. coli than S. aureus). For graphic purpose, “hvl-peak2, J” fits were forced to zero intercepts;

actual values were slightly below, but close to zero (0.074 J for E. coli, 0.071 J for S. aureus and Ribociclib ic50 0.21 J for E. coli dilution). This is consistent with the assumption of a diffused oxygen growth described by “hvl-peak2” that vanishes at zero air volume within the batch cell.

Total and peak values for Staphylococcus aureus average thermograms. c. Physiological saline dilution values for Escherichia coli thermograms. Specific heats are fitted with exponential trendlines, while absolute heats are fitted with linear ones. “hvl-peak1” and “hvl-peak2” represent the contributions of the two Peakfit components to the overall thermal effect.
