The effect of diurnal light cycles on biohydrogen production in a thermosiphon photobioreactor

Abstract

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.
