“…There was a decrease in inorganic carbon affinity with decreasing nitrogen supply with NH 4 + as nitrogen source in Chlamydomonas reinhardtii (Giordano et al 2003), resembling the results with the lowest NO 3 -concentrations used for Nannochloropsis (Hu and Zhou 2010). The increased CCM expression under NO 3 --nitrogen limitation accords with mechanistic considerations and with comparisons of C 3 (CO 2 diffusion) and C 4 (a C 4 -cycle based CCM) flowering plants on land (Raven 1990(Raven , 1991aRaven and Johnston 1991;Giordano et al 2005).…”

“…Using Chlorella, Kozłowska-Szerernol et al (2004) found an increased affinity for inorganic carbon under phosphorus limitation while Beardall et al (2005) found a decreased affinity in a different strain of Chlorella and different experimental conditions. Hu and Zhou (2010) found an increasing inorganic carbon affinity with increasing phosphorus limitation in Nannochloropsis. Increasing affinity for inorganic carbon in two of the three P-deficient algae seems at odds with the known decreased efficiency of energy transformation, at least for respiration where there is a lower ATP per glucose oxidised in P-deficient green algae (Theodorou and Plaxton 1993), although less is known of what happens under photosynthetic conditions (Weng et al 2008).…”

“…there was a decreased inorganic carbon affinity in moving from the second-lowest to the lowest NO 3 -concentration used, but a decreased inorganic carbon affinity in the single case in which NH 4 + was the nitrogen source (Giordano et al 2005;Raven et al 2005bRaven et al , 2008Young and Beardall 2005;Hu and Zhou 2010).…”

Algal and aquatic plant carbon concentrating mechanisms in relation to environmental change

Abstract.Carbon dioxide concentrating mechanisms (also known as inorganic carbon concentrating mechanisms; both abbreviated as CCMs) presumably evolved under conditions of low CO 2 availability. However, the timing of their origin is unclear since there are no sound estimates from molecular clocks, and even if there were, there are no proxies for the functioning of CCMs. Accordingly, we cannot use previous episodes of high CO 2 (e.g. the Palaeocene-Eocene Thermal Maximum) to indicate how organisms with CCMs responded. Present and predicted environmental change in terms of increased CO 2 and temperature are leading to increased CO 2 and HCO 3 -and decreased CO 3 2-and pH in surface seawater, as well as decreasing the depth of the upper mixed layer and increasing the degree of isolation of this layer with respect to nutrient flux from deeper waters. The outcome of these forcing factors is to increase the availability of inorganic carbon, photosynthetic active radiation (PAR) and ultraviolet B radiation (UVB) to aquatic photolithotrophs and to decrease the supply of the nutrients (combined) nitrogen and phosphorus and of any non-aeolian iron. The influence of these variations on CCM expression has been examined to varying degrees as acclimation by extant organisms. Increased PAR increases CCM expression in terms of CO 2 affinity, while increased UVB has a range of effects in the organisms examined; little relevant information is available on increased temperature. Decreased combined nitrogen supply generally increases CO 2 affinity, decreased iron availability increases CO 2 affinity, and decreased phosphorus supply has varying effects on the organisms examined. There are few data sets showing interactions among the observed changes, and even less information on genetic (adaptation) 2 changes in response to the forcing factors. In freshwaters, changes in phytoplankton species composition may alter with environmental change with consequences for frequency of species with or without CCMs. The information available permits less predictive power as to the effect of the forcing factors on CCM expression than for their overall effects on growth. CCMs are currently not part of models as to how global environmental change has altered, and is likely to further alter, algal and aquatic plant primary productivity.Keywords CO 2 concentrating mechanism -combined nitrogen -inorganic carboniron -mixing depth -photosynthetically active radiation -phosphorus -temperature -UVA-UVB Abbreviations CCM CO 2 concentrating mechanism DOC Dissolved organic carbon PAR Photosynthetically active radiation (400-700 nm)Rubisco Ribulose bisphosphate carboxylase-oxygenase UVA Ultraviolet A radiation (320-400 nm) UVB Ultraviolet B radiation (280-320 nm)

“…Studies on other green algae have revealed that low P conditions influence photosynthesis, C i acquisition and the size of a C i concentrating mechanism (CCM, Beardall et al 2005;Hu and Zhou 2010;Kozlowska-Szerenos et al 2004). As shown in the green alga Chlorella emersonii, a P-limitation hampers active processes such as the high-affinity uptake of C i (i.e., the realization of a low K 0.5 ) and a CCM .…”

“…As shown in the green alga Chlorella emersonii, a P-limitation hampers active processes such as the high-affinity uptake of C i (i.e., the realization of a low K 0.5 ) and a CCM . Contrasting results were reported for Chlorella vulgaris and Nannochloropsis sp., both realizing highaffinity C i uptake under low P conditions (Hu and Zhou 2010;Kozlowska-Szerenos et al 2004). In these two studies a CCM was not determined, but because a highaffinity C i uptake and CCM are considered related processes, both Chlorella vulgaris and Nannochloropsis sp.…”

The CO(2) acquisition was analyzed in Chlamydomonas acidophila at pH 2.4 in a range of medium P and Fe concentrations and at high and low CO(2) condition. The inorganic carbon concentrating factor (CCF) was related to cellular P quota (Q(p)), maximum CO(2)-uptake rate by photosynthesis (V(max,O2)), half saturation constant for CO(2) uptake (K(0.5)), and medium Fe concentration. There was no effect of the medium Fe concentration on the CCF. The CCF increased with increasing Q(p) in both high and low CO(2) grown algae, but maximum Q(p) was 6-fold higher in the low CO(2) cells. In high CO(2) conditions, the CCF was low, ranging between 0.8 and 3.5. High CCF values up to 9.1 were only observed in CO(2)-limited cells, but P- and CO(2)-colimited cells had a low CCF. High CCF did not relate with a low K(0.5) as all CO(2)-limited cells had a low K(0.5) (<4 μM CO(2)). High C(i)-pools in cells with high Q(p) suggested the presence of an active CO(2)-uptake mechanism. The CCF also increased with increasing V(max,O2) which reflect an adaptation to the nutrient in highest demand (CO(2)) under balanced growth conditions. It is proposed that the size of the CCF in C. acidophila is more strongly related to porter density for CO(2) uptake (reflected in V(max,O2)) and less- to high-affinity CO(2) uptake (low K(0.5)) at balanced growth. In addition, high CCF can only be realized with high Q(p).

Global warming caused by carbon dioxide (CO2) emissions is one of the most important topics of concern in the fields of science, environment and global economy. Carbon dioxide emissions have increased dramatically in recent years, and this trend is likely to continue with a projected increase of both global energy consumption and CO2 emissions by 51% in 2050 compared with 2005. To mitigate the negative impacts arising, a potential strategy to convert CO2 into renewable fuels or valuable chemicals can be applied. Bio‐CO2 emission reduction is receiving more and more attention as an environmentally friendly method. Microalgae are attracting worldwide attention in this regard owing to their exceptional speed of growth, resistance to harsh environments and low production costs. In this review, the biochemical principles of microalgae‐CO2 fixation and the research progress of microalgae strains used for CO2 fixation are reviewed and discussed. The latest progress in the co‐development of a microalgae carbon sequestration industry and other industries are provided, along with a survey of the progress in methods to improve microalgae‐CO2 fixation. Finally, the problems to be solved in the industry and its future directions of development are clarified. © 2021 Society of Chemical Industry (SCI).
