From: Effect of modeled reduced gravity conditions on bacterial morphology and physiology
Bacterial growth curves (based on OD at 600 nm) under modeled reduced gravity (MRG) and normal gravity (NG) conditions, for E. coli in LB ( A ) and in M9 minimal media ( B ); for S. aureus in LB ( C ) and in dilute (1/50) LB ( D ). Down and up-arrows on growth curves indicate the time points at which exponential and stationary phase samples were collected, respectively. Bacterial specific growth rates (μmax; h-1) (E) and growth yields (maximum OD at 600 nm) (F) under MRG and NG conditions in various culture media. Values are means (n = 3) and the error bars represent ± standard error of the mean. * = Statistically significant difference between MRG and NG (Student's t-test, P < 0.05).
