Key Trends in Algal Photobioreactor Performance
(A) Biomass production rate per unit time and per unit area, P, as a function of instantaneous photon flux density. Under continuous light, the instantaneous and time-averaged photon flux densities are identical. For pulsed light, however, Iinstantaneous refers to its value only during Tpulse, which is why P can be noticeably greater under pulsed light.
(B) The corresponding variation of P/I (biomass production per photon) with instantaneous photon flux density.
