Extracting information on the evolution of living- and dead-cell fractions of Salmonella Typhimurium colonies in gelatin gels based on microscopic images and plate-count data.

|Both cell number and colony volume of Salmonella Typhimurium in gelatin were monitored during the exponential and the stationary phase with varying pH and water activity, by plate counts and microscopic image analysis respectively.
|Calculated from table µ=0.3648 according to formula Doubling time=ln2/µ. Table gives Numerical values (±SE) of the parameter fits of (log transformed) cell density and colony volume at pH 5.25 – water activity 0.980 and at pH 4.50 – water activity 0.975. Water activity=0.98. This value is very similar to doubling time of colony volume 1.94 hours, BNID 104462
