Table 1 Detection time equations for the relationships between initial microbial cell densities (log (cfu/ml)) and detection times (isothermal microcalorimetry thermal power values) for strains Pseudomonas brassicacearum MA250, Bacillus amyloliquefaciens subsp. plantarum UCMB5113 and Clonostachys rosea IK726. In all strains, initial cell densities correlated with thermal power values. The results represent the averages of 2–4 independent experiments
