Growth on sorbitol as sole carbon source Growth ability ofP. agglomeransstrains on sorbitol was studied using 200-μl microcultures in 100-well Bioscreen C MBR system honeycomb plates (well volume 400 μl) at 24°C with regular shaking at 15-min intervals in M9 minimal medium containing 10 mM sorbitol as sole carbon source. All strains were grown overnight in LB, collected
by centrifugation, and washed twice with sterile 0.9% NaCl before being inoculated in M9 at an initial OD600of about 0.02. Growth curves were measured in triplicates by periodically quantifying the absorbance through a 420- to 580-nm wide band filter (OD420-580 nm) using a Bioscreen C MBR system (Growth Curves Oy, Helsinki, Finland). Growth at 24°C and 37°C Growth ability of selectedP. agglomerans sensu strictostrains EPZ015666 supplier was determined at 24°C and 37°C using the Bioscreen C MBR system. The protocol was the similar to that described above for growth on sorbitol, except SBI-0206965 order that LB medium was
used in place of minimal medium. The mean growth rate per hour (k) was calculated each 20 minutes according to the formula whereN 0andN t represent absorbance measured at two consecutive time points and Δtis the time interval (i.e., 1 h) between the two measurements. The highest optical density, the maximal growth rate, as well as the time needed to reach the latter value were recorded for each strain. A comparison of these parameters was performed among the average values obtained for clinical, biocontrol or plant-pathogenicP. agglomeransstrains. Correlations before between OD420-580 nmmeasured in the Bioscreen C MBR system and number of colony forming unit (CFU) was estimated for representative strains by dilution plating on LB agar.
