چکیده انگلیسی
For cycles of duration higher than 40Â s, microalgal response was close to the response assuming no L/D cycle effect (no light integration). Biomass growth rate showed responses at durations below 12Â s, which points to partial light integration resulting in an increase of measured biomass growth rate. This increase is known as the “L/D cycle effect”, where L/D cycle frequencies are found to generate positive effects for photosynthetic conversion. To investigate whether the growth increase was explained by L/D cycle effects, results were compared against the predictions of a kinetic model assuming no light integration but time-solved for light regimes corresponding to L/D cycles applied experimentally. The model was found to very accurately represent any of the light regimes applied, including those leading to an increase in biomass growth rate. It was then concluded that expected primary coupling between L/D cycles and photosynthetic conversion was negligible. The main influence was on pigment adaptation, which when integrated into the kinetic model assuming no L/D cycle effects was found to very accurately predict culture growth under all light regimes.
