Escherichia coli ATCC 8739 Adapts to the Presence of Sodium Chloride, Monosodium Glutamate, and Benzoic Acid after Extended Culture

Linear regression equations of generation times of the eight treatments. Negative linear regression gradient represents a decrease in generation time as the passage number increases. For example, a gradient of −2.02 in H COMB represents that the generation time decreases by 2.02 minutes in each passage. The intercept can be used as an estimator of the generation time at Passage 1.

Treatment	Linear regression equation
H COMB	Generation time = −2.02 Passage number + 271
L MSG	Generation time = −1.87 Passage number + 225
L BA	Generation time = −1.39 Passage number + 196
L SALT	Generation time = −1.24 Passage number + 189
L COMB	Generation time = −1.22 Passage number + 190
H BA	Generation time = −1.15 Passage number + 203
H SALT	Generation time = −1.12 Passage number + 181
H MSG	Generation time = −0.91 Passage number + 171
