Figure 2 : The difference in the length of the lag phase between the wild-type and ∆yeaG strain during ‘recovery’ growth is directly proportional to the length of time spent under N starvation.

From: Adaptation to sustained nitrogen starvation by Escherichia coli requires the eukaryote-like serine/threonine kinase YeaG

Figure 2

The ‘recovery’ growth curves of wild-type and ∆yeaG mutant strain were obtained by determining the OD600nm readings at half-hourly time points. The insert is a schematic representation of the experiment. The table summarizes growth parameters of wild-type and ∆yeaG mutant strain in ‘recovery’ growth following 20 min, 12 h, 18 h and 24 h in N starvation. Lag phase defined as the period up to and including OD600 = 0.1. The number in brackets indicates the percentage decrease in the length of the lag phase of the ∆yeaG mutant strain relative to the lag phase of the wild-type strain. The doubling time was determined from the slope of logarithmic growth function.
