  • * Doubling time in hours. Data are the mean ± standard deviation from three to five independent cultures for each condition. Starter cultures were from the same growth condition and were in mid- to late-logarithm phase (12–16 h old, <100 μg protein ml−1). Cultures were inoculated to a density of 2–4 μg protein ml−1

  • nmol CO2 assimilated (min⋅mg protein)−1. Data is the average of two independent log phase cultures. 

  • ND, not determined.
