**Figure 1.**Sketch of the ideal growth curve according to the proposed model. The latency gap of the present model substantially differs from the lag phase, λ, considered in preexisting models [7]

**Figure 2.**Gathered growth curves from a variety of microbes (Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, Salmonellae, C. jejuni, Pseudomonas fluorescens and Candida sake) adjusted from [18]. For further data, see also Figure 2 in [21]

**Figure 3.**The origin of the time scale of the microbial culture, θ, differs from that of the experimenter, t. The dashed line that allows calculation of θ_{0}corresponds to the level –β**/8. For 0 < θ < θ_{0}, the microbial culture experiences activities related to the incoming duplication (active latency gap). Plate count data come from a batch culture of Pseudomonas aeruginosa at 5°C [26]. Calculated values: t_{start}= -20 h; t_{0}= 12 h; θ_{0}= 32 h

**Figure 4.**Growth curves from different N_{0}inoculums, at the same temperature, aligned along the same straight line that corresponds to the same maximum specific duplication rate, μ

**Figure 5.**The width of the active latency gap, θ_{0}, vanishes for log_{2}(N_{0}) = log_{2}(N_{max})/9. At a given T, θ_{0}increases on increasing log_{2}(N_{0}), but decreases on increasing T. Its upper limit, log_{2}(N_{max})/μ, decreases on increasing T

**Figure****6****.**The maximum specific duplication rate increases with increasing temperature, while no significant changes concern the maximum population density, N_{max}. Such a behavior occurs for the batch cultures of psychrotrophic bacteria [21]

**Figure****7****.**The change of the temperature from T_{1}to T_{2}or T_{3}(T_{2}> T_{1}> T_{3}) modifies the growth trend. θ_{change}, is the new origin of the time scale for the culture and the corresponding level of the cell population is the new log_{2}(N_{0}). (θ_{0,2}– θ_{change}) and (θ_{0,3}– θ_{cha}_{nge}) are the intermediate latency gaps for the T_{1}→ T_{2}and T_{1}→ T_{3}temperature changes
