“…This resulted in the inhibition of the growth of the microalgae [ 31 ], where various microalgal species regulate their cellular content of zinc [ 33 ]. The cell density from marine microalgae Pleurochrysis roscoffensis after 96 h exposure to five different Zn concentrations (50, 100, 500, 1000, and 1500 µg L −1 ), and a control (free of added Zn), in non-acidified natural seawater revealed significant differences ( p < 0.01) of microalgae responses between concentrations of 500, 1000, and 1500 µg L −1 compared with the algae density of the control [ 34 ].…”

Biosorption refers to a physicochemical process where substances are removed from the solution by a biological material (live or dead) via adsorption processes governed by mechanisms such as surface complexation, ion exchange, and precipitation. This study aimed to evaluate the adsorption of Zn2+ in seawater using the microalgal biomass of Tetraselmis marina AC16-MESO “in vivo” and “not alive” at different concentrations of Zn2+ (0, 5, 10, and 20 mg L−1) at 72 h. Analysis was carried out by using the Langmuir isotherms and by evaluating the autofluorescence from microalgae. The maximum adsorption of Zn2+ by the Langmuir model using the Qmax parameter in the living microalgal biomass (Qmax = 0.03051 mg g−1) was more significant than the non-living microalgal biomass of T. marine AC16-MESO (Qmax = 0.02297 mg g−1). Furthermore, a decrease in fluorescence was detected in cells from T. marina AC16-MESO, in the following order: Zn2+ (0 < 20 < 5 < 10) mg L−1. Zn2+ was adsorbed quickly by living cells from T. marine AC16-MESO compared to the non-living microalgal biomass, with a decrease in photosystem II activities from 0 to 20 mg L−1 Zn2+ in living cells.

“…Besides, some of the physiological responses detected in this study are directly connected to growth efficiency, which might have ecological consequences, that is, eutrophication, especially supported by the high levels of GRs seen in this study, might lead to an ecosystem alteration. Previously, many other studies have upheld the eutrophication induced by high concentration of CO 2 (e.g., (42)). Therefore, this environmental risk would be interesting to assess considering how phytoplankton activity changes can alter the ecosystems (43).…”

Flow Cytometry Assessment of Microalgae Physiological Alterations under CO₂ Injection

Growth rate (GR), esterase activity (EA), membrane potential (MP), and DNA content were measured by flow cytometry to test if this powerful tool could be included in risk assessment and monitoring programs. This study tests a battery of endpoints that were measured on Scenedesmus (Acutodesmus) obliquus as model species, under high levels of injected CO 2 to be proposed as biomarkers of effect. New technologies such as carbon capture and storage (CCS) bring positive consequences on CO 2 mitigation strategies but also could have negative consequences if a CO 2 leakage occurs during injection. Under this scenario, pH might drop down to 4 pH units around the pipe where the leakage happens. The study focus on to ascertain if the endpoints fulfill the requirements such as sensitiveness, be timely and cost-effective, be easy to measure and interpret, and be nondestructive, valuable attributes in effective biomarkers. CO 2 injected at high levels significantly affects the EA, the membrane polarization, as well as GRs. However the DNA content did not shown a clear response under this condition. In conclusion, the GR, the EA, and the MP analyzed by flow cytometry fulfilled the attributes mentioned above and are proposed as biomarkers of effect in CCS monitoring programs.

“…The higher osmoregulatory capacity in both males and females of U. tangeri at high salinity (55 psu) compared with that in low salinity (12 psu), suggests a higher ability for hypo-osmoregulation. Whether this is linked with the fact that in Rio San Pedro, freshwater input from Cadiz Bay is relatively low so the salinity of the water is more usually high (Bautista- Chamizo et al ., 2016; Pereira et al ., 2016) remains to be investigated. Flexibility in osmoregulatory behaviour of euryhaline crabs determines a successful and/or differential occupancy of distinct areas in estuarine, inlets and coastal lagoons habitats that exhibit wide changes in environmental salinity.…”

This study constitutes a first attempt to investigate sex differences in osmoregulatory capacity and metabolic responses in relation to hyper- and hypo-osmoregulation in the intertidal euryhaline crab Uca tangeri. Adult male and female specimens from Cadiz Bay, Spain (36°23′–37′N 6°8′–15′W), were acclimated to three different environmental salinities (12, 33 and 55 psu) during 7 days, and several parameters were assessed in haemolymph (osmolality, glucose, amino acids, triglycerides and lactate) as well as in metabolic key organs (hepatopancreas, anterior and posterior gills: glycogen, free glucose, amino acids and triglycerides). Specimens from both sex exhibited high and similar hyper- and hypo-osmoregulatory capacities. However, metabolite levels were differentially affected upon acclimation to low and high salinity in several metabolic organs and haemolymph of male and females: (i) glycogen in gills, (ii) free glucose in gills and hepatopancreas, (iii) amino acids in hepatopancreas, (iv) triglycerides in haemolymph, hepatopancreas and posterior gills, and (v) lactate in haemolymph. The results suggest the occurrence of differential metabolic adjustments upon hyper- and hypo-osmoregulation related to sex in the intertidal euryhaline crab U. tangeri.
