In this study, we report on the results of an optimisation scheme for maximal biomass production under three different photoperiods (24:0, 16:08 and 12:12-h L/D) combined with three photon flux densities (PFD, 120, 220 and 460 µmol photons m<sup>-2</sup> s<sup>-1</sup>) at 25 °C. Sampling for growth took place in both the exponential and post-exponential (light-limited only) phase. Results showed that specific growth rate of T-ISO maximised with an increase of the total PFD supplied per day. Under continuous light, cell size of T-ISO (both cell dry weight (CDW) and cell volume) correlated positively to PFD with a further increase when the cells were transiently light-limited in the post-exponential phase. In contrast, cell dry weight under discontinuous light increased only at subsaturating PFD with a significant decrease in the post-exponential phase. Cell size, as volume, did not correlate to CDW under discontinuous light, revealing an intracellular density change particularly for the 16:08-h L/D regimes. As a result, biomass yield and productivity had different patterns for continuous and discontinuous light whereas cell yield and productivity were simply a function of total PFD per day. Biomass productivity under continuous light was inferior than under discontinuous light, although the final yield was maximal compared to those under discontinuous light.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Optimisation of T-ISO biomass production rich in essential fatty acids: 1.
