Effect of temperature (30°C, gray bars; 10°C, white bars) on maximum values of optical density (A), growth rate (B), viable cell counts (C), total cell counts (D), cell dry weight (E), and whole-cell protein content (F) of strains tested in a complex medium at the stationary growth phase. Data represent mean values (n = 3) of the isolates E. coli J55, L. monocytogenes Iso 11/13, S. xylosus J70, B. cereus J1, and P. nutrimenti J22T and the reference strains E. coli DSM 30083T, L. monocytogenes DSM 20600T, S. xylosus DSM 20266T, B. cereus DSM 31T, and P. panaciterrae LMG 23400T. No cell counts were determined for B. cereus J1 because of filamentous growth on solid and liquid media. *, statistically significant differences (t test, P < 0.05) between the temperatures for each strain. Values marked with “n.s.” are not significantly different.
