Abstract: The basic minimal media (BMM) containing 0%, 3.5% or 5% NaCl and 20 mg/kg betaine Salmonella SL1344 were used to culture Salmonella enterica SL 1344 at an inoculum level of 103 CFU/mL in a constant temperature oven or at lower inoculum gradients in a Bioscreen for growth curve investigations. In addition, the growth of single cells under the condition of 3.5% NaCl was explored. The results showed that the growth distribution of cell colonies was determinative. By contrast, the growth distribution of single cells was stochastic. The relationship between the growth of single cells and cell colonies could be modeled.

Key words: Salmonella enterica, growth model, single cell, flow chamber, stochastic distribution, determinative distribution
