The effect of diurnal light cycles on biohydrogen production in a thermosiphon photobioreactor [PDF]
AMB Express, 2023 Key points The thermosiphon photobioreactor can operate under diurnal light cycles. Diurnal light cycles reduce hydrogen productivity of R. palustris. Diurnal light cycles have little to no effect on the growth of R palustris.
