“…In particular, the p-carotene increase in L1 grown cultures, quite comparable with that observed both in 0 . agardhii (Millie et al 1990) and in Spirulina platensis (Olaizola & Duerr 1990), is in agreement with a light-harvesting or structural role of this pigment in the photosystem I (Olaizola & Duerr 1990). Therefore, our results indicate that in the strain 3F carotenoids may serve as an accessory pigment and for photoprotection.…”

Data on acclimation to 2 photon flux densities (15 and 100 pm01 photons m-2 S-') in Spirulina subsalsa strain 3F, a highly fluorescent phycoerythrin-rich cyanobacterium isolated from the brackish Lake Faro (Messina, Italy), indicated plasticity of the photosynthetlc apparatus of this organIsm. High-irradiance grown cells showed the greatest photosynthetlc capacity even though they had a lower chlorophyll and phycobiliprotein content. Carotenoids decreased to a lesser extent but their composition changed. b-carotene decreased, while the amount of myxoxanthophyll more than doubled. The stability of both C-phycoerythrin and C-phycocyanin ratios in cells grown under different light quality (green and red) demonstrated the lack of complementary chromatic adaptation in S. subsalsa. This factor, combined with the efficient utilization of low-wavelength light, indicates the strong adaptation of this strain to its habitat.

“…This indicates that C. officinalis can be photoacclimated to high light intensities by changing photosynthetic pigment content to optimize photosynthetic rate. carotenoids content of C. officinalis also increased at low light, as in the green alga Spirulina platensis (Olaizola and Duerr 1990). This supports the hypotheses that carotenoids are closely associated with chlorophyll a content, that they increase at low light intensity, and that they serve as light harvesting pigments or a structural component of photosystem I (Olaizola and Duerr 1990).…”

The coralline alga, Corallina officinalis, is a widely distributed intertidal species in temperate coastal regions. It is usually exposed to high fluctuations of light intensity, light quality, temperature, and desiccation, all of which affect the temporal and spatial distribution as well as the morphology and the metabolism of this alga. In laboratory experiments we examined the effects of different light intensities (50, 100, and 200 μmol photons m -2 s -1) on photosynthesis, calcification, photosynthetic pigment contents (chlorophyll a and carotenoids), and growth rate of C. officinalis to clarify its photoacclimation strategies. Net photosynthesis, calcification and dissolution rates based on weight were not sensitive to irradiance. Although, photosynthesis and calcification did not clearly respond to light intensity, photosynthetic pigment contents were significantly lower at higher light intensities. In addition, higher irradiances induced significant enhancement of gross photosynthesis based on chlorophyll a. As a result, the specific growth rate was significantly stimulated by high light intensity. Our results suggest that photoacclimation of C. officinalis to different light conditions may be regulated to optimize growth.

“…A linear relationship was found between growth rates and light intensity (Figure 8), except for the first point at 85 µmol/m 2 /s. Light saturation could not be reached at 430 µmol/m 2 /s, while some studies found photoinhibition around 300 µmol/m 2 /s [29] or 432 µmol/m 2 /s [30]. These differences might be explained by different Spirulina strain and different lighting conditions.…”

Optimization of Arthrospira platensis (Spirulina) Growth: From Laboratory Scale to Pilot Scale

et al. 2017

Arthrospira platensis (Spirulina) is the most cultivated microalga worldwide. Improving its cultivation in terms of biomass productivity, quality, or production cost could significantly impact the Spirulina industry. The objectives of this paper were defined as to contribute to this goal. Spirulina biomass productivity was investigated through medium choice. A modified Zarrouk's medium was selected as it gave higher final dry weights and longer sustained growth than Hiri's and Jourdan's media. Then, in order to reduce Spirulina production cost, modified Zarrouk's medium was rationalized by testing different dilutions. It was found that modified Zarrouk's medium could be diluted up to five times without impacting the growth rates in a 28-days batch cultivation. Higher dry weights were even observed after 21 days of batch cultivation (1.21 g/L for 20%-modified Zarrouk's medium in comparison to 0.84 g/L for modified Zarrouk's medium). Iron uptake was then investigated as one of the major contributors to Spirulina nutritional quality. An increase in iron content was obtained by replacing iron sulfate by iron EDTA at a concentration of 10 mg Fe /L (2.11 ± 0.13 mg Fe /g biomass for EDTA-FeNa,3H 2 O at 10 mg Fe /L compared to 0.18 ± 0.13 for FeSO 4 ,6H 2 O at 2 mg Fe /L). Impact of light intensity on Spirulina biomass productivity was also investigated in a 2 L Photobioreactor (PBR). Specific growth rates were calculated for Photosynthetically Photon Flux Densities (PPFD) from 85 to 430 µmol/m 2 /s. At 430 µmol/m 2 /s, photoinhibition was not observed and the specific growth rate was maximum (0.12/day). Finally, a 40-day cultivation experiment was conducted in a 1000 L PBR giving a maximum daily areal productivity of 58.4 g/m 2 /day. A techno-economic analysis gave production cost two to 20 times higher for PBR (from 18.71 to 74.29 €/kg) than for open ponds (from 3.86 to 9.59 €/kg) depending on Spirulina productivity.
