“…Chen et al [15] evaluated the effect of nitrate and they reported that a sufficient amount of nitrogen in the medium was required to enhance lutein accumulation in the Chlorella sorokiniana Mb-1 strain. More importantly, it could be possible that the lutein content may depend on the residual nitrogen concentration [14]. Figure 4 illustrates the effect of CO2 content on nutrient consumption, measured at the end of the growth of S. almeriensis.…”

“…Scenedesmus almeriensis, being the highest lutein natural producer, has attracted growing interest and it represents the only commercialized microalgae for pigment extraction [9][10][11][12]. Lutein is classified as a primary xanthophyll because of the presence of two hydroxyl functional groups in the structure [13][14][15]. It acts as a light energy harvesting compound, which improves the photosynthesis efficiency and it prevents photodamage [16].…”

In this study, Scenedesmus almeriensis as green microalga was cultivated on bench-scale for carbon dioxide (CO2) capture and lutein production. The autotrophic cultivation of S. almeriensis was carried out by using a vertical bubble column photo-bioreactor (VBC-PBR) with a continuous flow of a gaseous mixture of oxygen (O2), nitrogen (N2), and CO2, the latter in content of 0.0–3.0 %v/v. The liquid phase was batch. S. almeriensis growth was optimized. In addition, lutein extraction was carried out by using accelerated solvent extraction with ethanol as Generally Recognized as Safe (GRAS) solvent at 67 °C and 10 MPa. Upon optimization of CO2 concentration, the maximum biomass productivity, equal to 129.24 mg·L−1·d−1, was achieved during the cultivation by using a content of CO2 equal to 3.0 %v/v and it allowed to obtain a lutein content of 8.54 mg·g−1, which was 5.6-fold higher in comparison to the analogous process carried out without CO2 addition. The ion chemical analysis in the growth medium showed that by gradually increasing CO2 content, the nutrient consumption during the growth phase also increased. This study may be of potential interest for lutein extraction at industrial scale, since it is focused on pigment production from a natural source with a concomitantly CO2 capture.

“…Six different CO 2 concentrations (0.03, 2.5, 5.0, 7.5, 10.0, and 12.5%) were used. The biomass productivity and the specific growth rate were higher when CO 2 concentration increased from 0.03 to 2.5% and decreased when CO 2 concentration was further increased to 12.5% (Xie et al, 2017). On the basis of the above-mentioned studies 3.0% was chosen as maximum value to evaluate the effect of CO 2 concentration in this study.…”

“…Lutein is a carotenoid found in plants and phototrophic microorganisms. It is classified as a primary xanthophyll because of the presence of two hydroxyl functional groups in its chemical structure (Chen et al, 2017;Xie et al, 2017;Bowen et al, 2018). Lutein acts as a light-harvesting pigment that improves photosynthesis efficiency and prevents photo-damage in plant cells (Ruban et al, 2007).…”

Enhancing Biomass and Lutein Production From Scenedesmus almeriensis: Effect of Carbon Dioxide Concentration and Culture Medium Reuse

et al. 2020

The main purpose of this study is to investigate the effects of operative parameters and bioprocess strategies on the photo-autotrophic cultivation of the microalgae Scenedesmus almeriensis for lutein production. S. almeriensis was cultivated in a vertical bubble column photobioreactor (VBC-PBR) in batch mode and the bioactive compounds were extracted by accelerated solvent extraction with ethanol at 67 • C and 10 MPa. The cultivation with a volume fraction of CO 2 in the range 0-3.0%v/v showed that the highest biomass and lutein concentrations-3.7 g/L and 5.71 mg/g, respectively-were measured at the highest CO 2 concentration and using fresh growth medium. Recycling the cultivation medium from harvested microalgae resulted in decreased biomass and lutein content. The nutrient chemical composition analysis showed the highest consumption rates for nitrogen and phosphorus, with values higher than 80%, while sulfate and chloride were less consumed.

Marine microalgae has great potential for lutein production with the advantage of saving fresh water resource. Thus, marine microalga Chlamydomonas sp. JSC4 is investigated as a potential lutein producer in this study. The medium types, nitrate‐N and sea salt concentration are individually investigated to promote the cell growth rate and lutein production of JSC4. In Modified Bold Basal 3N medium, cell growth and lutein content are optimal at the nitrate‐N concentration of 1000 mg L−1 and sea salt concentration of 2%. In addition, an innovative salinity‐gradient strategy is operated to dramatically enhance biomass productivity (560 mg/L/d) and lutein content (3.42 mg g−1), resulting in the optimal lutein productivity (1.92 mg/L/d). Overall, this study clearly demonstrates that salinity is a significant inducer of lutein accumulation by strain JSC4 and that lutein production can be successfully optimized using the salinity‐gradient strategy, which is beneficial for the outdoor large‐scale lutein production in the future.
