“…0%, current study and [33]), and comparable to those reported for species of marine macroalgae characterized as having a high lipid content (10-12% DW, [18]). To our knowledge, this is the first time that salinity has been reported to significantly affect the lipid content of macroalgae, as other factors (temperature and nutrients) are more commonly recognized as drivers [16,19,24]. However, in contrast to the increases in protein content under increased salinity, the increases in lipid content for strain Tsv1 were not large enough to offset the significant decreases in productivity with increasing salinity and, consequently, lipid productivity for all strains except Tar1 decreased with increasing salinity.…”

“…In addition to the sampling period, the location may account for any difference (Munier et al ., ; Rodrigues et al ., ). The total amount of FAs and the FA profile have shown a substantial dependency on environmental factors, such as light and temperature, thereby suggesting the potential for environmental manipulation to improve the productivity and quality of FAs in seaweed (Gosch et al ., ).…”

“…In addition to the sampling period, the location may account for any difference (Munier et al, 2013;Rodrigues et al, 2015). The total amount of FAs and the FA profile have shown a substantial dependency on environmental factors, such as light and temperature, thereby suggesting the potential for environmental manipulation to improve the productivity and quality of FAs in seaweed (Gosch et al, 2015). Nevertheless, the current study's results and those in the literature seem to support some of the general trends observed in specific taxa, namely, brown seaweed species may be rich in myristic, palmitic, oleic and linoleic FAs (Khotimchenko et al, 2002;Schmid et al, 2014;Akg€ ul et al, 2015).…”

Summary The Azorean macroalgae Petalonia binghamiae, Halopteris scoparia and Osmundea pinnatifida are undervalued and require further study regarding their potential use as food. These three seaweed species had low fat contents, and their fatty acid (FA) profiles were characterised by a high proportion of saturated FA (SFA) in the case of O. pinnatifida and similar weights of SFA and polyunsaturated FA (PUFA) in the other two species. Within the PUFAs, the ω3 PUFAs were the most prominent in O. pinnatifida and P. binghamiae, yielding ω3/ω6 ratios that were higher than one. Eicosapentaenoic acid (EPA, 20:5 ω3) was the most important ω3 PUFA (10–14%). Regarding the other bioactive compounds, the polyphenols were found to reach non‐negligible levels (140–220 mg/100 g dw). Significant antioxidant activity was detected. Ethanolic extracts of H. scoparia and aqueous extracts of P. binghamiae showed cyclooxygenase‐2 (COX‐2) inhibitory capacities between 40% and 79%, indicating anti‐inflammatory activity.

“…Macroalgae generally exhibit significant changes in both lipids and fatty acids with changing environmental conditions. Such biochemical changes can be observed in the biomass very shortly after exposure (≤7 days) as an acclimation mechanism in membrane and/or storage lipids (Al‐Hasan, Hantash, & Radwan, ; Gosch, Lawton, Paul, Nys, & Magnusson, ). Elevated CO 2 concentrations have been shown to either increase or decrease the lipid production of several species of algae, especially when combined with nutrient limitation (Bermúdez et al, ; Sun, Chen, & Du, ).…”

Responses of macroalgae to CO₂ enrichment cannot be inferred solely from their inorganic carbon uptake strategy

Increased plant biomass is observed in terrestrial systems due to rising levels of atmospheric CO2, but responses of marine macroalgae to CO2 enrichment are unclear. The 200% increase in CO2 by 2100 is predicted to enhance the productivity of fleshy macroalgae that acquire inorganic carbon solely as CO2 (non‐carbon dioxide‐concentrating mechanism [CCM] species—i.e., species without a carbon dioxide‐concentrating mechanism), whereas those that additionally uptake bicarbonate (CCM species) are predicted to respond neutrally or positively depending on their affinity for bicarbonate. Previous studies, however, show that fleshy macroalgae exhibit a broad variety of responses to CO2 enrichment and the underlying mechanisms are largely unknown. This physiological study compared the responses of a CCM species (Lomentaria australis) with a non‐CCM species (Craspedocarpus ramentaceus) to CO2 enrichment with regards to growth, net photosynthesis, and biochemistry. Contrary to expectations, there was no enrichment effect for the non‐CCM species, whereas the CCM species had a twofold greater growth rate, likely driven by a downregulation of the energetically costly CCM(s). This saved energy was invested into new growth rather than storage lipids and fatty acids. In addition, we conducted a comprehensive literature synthesis to examine the extent to which the growth and photosynthetic responses of fleshy macroalgae to elevated CO2 are related to their carbon acquisition strategies. Findings highlight that the responses of macroalgae to CO2 enrichment cannot be inferred solely from their carbon uptake strategy, and targeted physiological experiments on a wider range of species are needed to better predict responses of macroalgae to future oceanic change.
