Values of the efficiency factor c varied with irradiance from 0·23 at 0·5 W m−2 to 0·05 at 40 W m−2. The specific maintenance rate constant was 0·001 h−1. The culture pH value influenced c and μ e . A diurnal light/dark cycle with a 16 h photoperiod did not affect either of the two parameters, μ e and c. The relationship between growth rate and light energy uptake rate, embodied in the above formula, was also valid for nitrogen (nitrate)-limited cultures. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-115-1-153
