Regression analyses of cell concentrations (log (cfu/ml)) and detection times (h) at certain thermal power values to determine the correlation and resolution of isothermal microcalorimetry thermal power curves for the quantification of microbial densities. a The Pseudomonas brassicacearum MA250 resolution in pure culture was ~ 0.2–0.4 log (cfu/ml). b The P. brassicacearum MA250 resolution after seed coating was ~ 0.5–1 log (cfu/g seed). c Different thermal power (500 μW and 800 μW) time points of P. brassicacearum MA250 pure cultured samples and coated seed samples fitted into the same regression curve despite of the differences in the resolution per treatment (see Fig. 3a and b). d The Bacillus amyloliquefaciens subsp. plantarum UCMB5113 strain’s resolution in pure culture was ~ 0.6–0.8 log (cfu/ml). e The Clonostachys rosea IK726 resolution in pure culture was ~ 1–1.5 log (cfu/ml). The figures represent the averages and standard deviations of 2–3 independent experiments with 3–6 replicates each
