“…and Isochrysis sp. are commonly cited in various literature, discussing and highlighting their capability in producing good quality of biomass yield, lipid content, nutritional values and antioxidant properties 7 , 23 , 24 . Thus, these local species can be considered potential microalgal biomass for scale-up and further studies on the rate and optimization of CO 2 fixation from a coal-fired power station in Malaysia.…”

Global warming has become a serious issue nowadays as the trend of CO2 emission is increasing by years. In Malaysia, the electricity and energy sector contributed a significant amount to the nation’s CO2 emission due to fossil fuel use. Many research works have been carried out to mitigate this issue, including carbon capture and utilization (CCUS) technology and biological carbon fixation by microalgae. This study makes a preliminary effort to screen native microalgae species in the Malaysian coal-fired power plant’s surrounding towards carbon fixation ability. Three dominant species, including Nannochloropsis sp., Tetraselmis sp., and Isochrysis sp. were identified and tested in the laboratory under ambient and pure CO2 condition to assess their growth and CO2 fixation ability. The results indicate Isochrysis sp. as the superior carbon fixer against other species. In continuation, the optimization study using Response Surface Methodology (RSM) was carried out to optimize the operating conditions of Isochrysis sp. using a customized lab-scale photobioreactor under simulated flue gas exposure. This species was further acclimatized and tested under actual flue gas generated by the power plant. Isochrysis sp. had shown its capability as a carbon fixer with CO2 fixation rate of 0.35 gCO2/L day under actual coal-fired flue gas exposure after cycles of acclimatization phase. This work is the first to demonstrate indigenous microalgae species' ability as a carbon fixer under Malaysian coal-fired flue gas exposure. Thus, the findings shall be useful in exploring the microalgae potential as a biological agent for carbon emission mitigation from power plants more sustainably.

“…where Y is the response variable, β 0 is the interception coefficient, β i and β ii are model coefficients of the first and second order, respectively, β ij is the linear model coefficient for interaction between the independent variables i and j; X i and X j are factors, respectively and ε is random error [36]. The relationship between the independent variables and response variables were then further revealed using the equation.…”

Combined planting of submerged macrophytes could be an effective way of controlling algal blooms in landscape waters. In this study, the algal inhibition of single and combined planting of Hydrilla verticillata (A) and Myriophyllum spicatum (B) were explored. The optimized combined planting conditions were investigated using the central composite design. The results showed that the combined planting had a synergistic algal-inhibiting effect. Its inhibition (I (K)) is about 10.8% higher than that of single planting with the same density. The synergism of the combined planting may be due to the different ways in which the two plants inhibit the algal growth. H. verticillata inhibited the algal biomass and M. spicatum inhibited the algal specific growth rate. When the density of H. verticillata and M. spicatum were 7.2 g/L and 6.7 g/L, the value of I (K) reached a maximum 92.2%. Although increasing planting density would improve the algal inhibition, high planting density was not beneficial for the growth of plants. Moreover, no further significant improvement was shown with the increasing planting density when the value of I(K) was higher than 90%. Therefore, the cost-effective combined macrophyte density was 11.6 g/L and the value of A/B ranged from 1.05 to 1.07, where the value of I (K) could achieve 90%. This study can provide a practical basis for using macrophytes to control algal blooms.

“…The maximum CO 2 fixation rate of Chlorella pyrenoidosa SJTU-2 and Scenedesmus obliquus SJTU-3 was 0.26 and 0.29 g L −1 d −1 at 10% CO 2 , respectively [ 9 ]. The CO 2 fixation rate of Nanochloropsis was 0.22 g L −1 d −1 under simulated flue gas (11% CO 2 , 10% O 2 , 1–2% CO, and 500 ppm CH 4 and N 2 ) [ 15 ]. The CO 2 fixation rate of Scenedesmus obliquus PF3 reached 0.75 g L −1 d −1 within simulated flue gas (10% CO 2 and 100 ppm NO) [ 16 ].…”

In this study, Scenedesmus sp. FSP3 was cultured using a two-stage culture strategy for CO2 fixation and lutein production. During the first stage, propylene carbonate was added to the medium, with 5% CO2 introduced to promote the rapid growth and CO2 fixation of the microalgae. During the second stage of cultivation, a NaCl concentration of 156 mmol L−1 and a light intensity of 160 μmol m−2 s−1 were used to stimulate the accumulation of lutein in the microalgal cells. By using this culture method, high lutein production and CO2 fixation were simultaneously achieved. The biomass productivity and carbon fixation rate of Scenedesmus sp. FSP3 reached 0.58 g L−1 d−1 and 1.09 g L−1 d−1, with a lutein content and yield as high as 6.45 mg g−1 and 2.30 mg L−1 d−1, respectively. The results reveal a commercially feasible way to integrate microalgal lutein production with CO2 fixation processes.
