“…Under nitrate phosphate co-deprivation the total lipid content increased by 5% with bicarbonate addition. As reported by Pancha et al (2015) this result indicates that the inorganic carbon supply under nitrogen starvation conditions helps in de novo synthesis of microalgal lipids [34]. Hence, the strategic addition of sodium bicarbonate was found to enhance the growth and lipid accumulation in Chlorella sp.…”

The present study aims towards the investigation of lipid production capability of microalgae isolated from coal mining site. The biomass production and lipid productivity of the isolate was studied under the influence of different bicarbonate, nitrate, and phosphate concentration. The production of biomass was observed to be highest at 8.4, 0.75, and 0.06 gL 21 of bicarbonate, nitrate, and phosphate concentrations. The role of bicarbonate supplementation under different nutritional starvation conditions viz. N1 P1, N-P-, N1 P-, and N-P1 with and without sodium bicarbonate respectively was also evaluated. Addition of sodium bicarbonate increased the lipid content to 35% of dry cell weight (DCW) and carbohydrate content to 52% of DCW under the nitrate and phosphate nutritional starvation conditions. The results revealed that the microalgae grown in sodium bicarbonate can be a promising feedstock for biodiesel production.

“…Carbonic anhydrases are key regulatory and detoxifying enzymes for plants that are upstream regulators of CO 2 -controlled stomatal movements and are also an important tool for plants to assimilate HCO 3 − [12,14]. In this experiment, the CA activity profile of the three species was assayed at seven-day intervals during the drought stress phase.…”

Abstract:To determine whether the bicarbonate in karst limestone soil could be used as a new carbon resource for biomass production by the catalysis of carbonic anhydrase (CA), a simulative karst drought stress experiment was designed and performed. Three plants used for biofuel energy,, and Euphorbia lathyris L. (El), were grown under simulated karst drought stress. In response to drought stress, the photosynthesis of the three energy plants was inhibited, but their CA activity increased. The hypothesis was confirmed by plant physiological and stable isotope techniques. The obtained results showed that plant biomass was produced with atmospheric CO 2 as well as bicarbonate under drought stress. Bicarbonate use was proportional to the CA activity of the plants. With high CA activity over a long period, El had the highest proportional bicarbonate use compared to Ov and Bj, reaching 26.95%. Additionally, a new method is proposed for the screening of plants grown for energy in karst habitats.

Selecting the optimal microalgal strain for carbon capture and biomass production is crucial for ensuring the commercial viability of microalgae‐based biorefinery processes. This study aimed to evaluate the impact of varying bicarbonate concentrations on the growth rates, inorganic carbon (IC) utilization, and biochemical composition of three freshwater and two marine microalgal species. Parachlorella kessleri, Vischeria cf. stellata, and Porphyridium purpureum achieved the highest carbon removal efficiency (>85%) and biomass production at 6 g L−1 sodium bicarbonate (NaHCO3), while Phaeodactylum tricornutum showed optimal performance at 1 g L−1 NaHCO3. The growth and carbon removal rate of Scenedesmus quadricauda increased with increasing NaHCO3 concentrations, although its highest carbon removal efficiency (∼70%) was lower than the other species. Varying NaHCO3 levels significantly impacted the biochemical composition of P. kessleri, S. quadricauda, and P. purpureum but did not affect the composition of the remaining species. The fatty acid profiles of the microalgae were dominated by C16 and C18 fatty acids, with P. purpureum and P. tricornutum yielding relatively high polyunsaturated fatty acid content ranging between 14% and 30%. Furthermore, bicarbonate concentration had a species‐specific effect on the fatty acid and chlorophyll‐a content. This study demonstrates the potential of bicarbonate as an effective IC source for microalgal cultivation, highlighting its ability to select microalgal species for various applications based on their carbon capture efficiency and biochemical composition.
