Fig. 5

Correlation between the genome reduction and decay rate. a. Genome reduction dependent changes in both growth and decay rates. The mean growth rates (r, upper) and mean decay rates (d, bottom) are a result of the fitting of the growth curves in M63 with the modified logistic model and are shown based on the order of the strain No. The genomes of strain Nos. 1~ 28 stand for reduced genomes, and No. 0 indicates the wild-type genome W3110. The standard errors of the growth curves/tests (N = 12~ 28) of the same strain are indicated. The broken lines in red represent the linear regression. b. The difference between the growth rates evaluated by CFU and OD600. The growth rates evaluated by OD600 and CFU are indicated as μOD and μCFU, respectively. The changes in growth rates were calculated according to the results from Fig. 2c. The reduced genomes are shown as strain Nos. 7, 14, 20 and 28 in the order of the length of the genome reduction from short to long
