Carbon dioxide emission is one of the main causes of global warming, which is caused by the evolution of the atmosphere from a mixture of gases originating from the interior of the earth. To overcome the problem of CO2 gas emissions, efforts have been made to reduce CO2 emissions by capturing CO2 with the Carbon Capture Storage (CCS) method, which aims to reduce carbon emissions released into the atmosphere. Biological CO2 capture generally uses microalgae cultivation. Previous research has used an open pond development system, with varied types of microalgae. In this study, CO2 capture was carried out using microalgae species Chlorella pyrenoidosa in a photobioreactor (PBR). This study results an optimum biomass productivity for Chlorella pyrenoidosa, the variation of NaHCO3 0 ppm is 4.090 g. l−1. d−1 on day 7, followed by variation of flow rate is is 2.844 g. l−1. d−1 on day 7. Suggestions for further research is to calculate the optimal cost incurred at the optimal CO2 concentration that can be captured by microalgae and the resulting increase in the value of the biomass microalgae that can be produced so that the use of microalgae can carried out comprehensively.

“…Chlorella pyrenoidosa (C. pyrenoidosa) is a green alga with a long history that is widely used as a food supplement worldwide. Most C. pyrenoidosa is found growing in fresh water environments; however, some marine types of C. pyrenoidosa can also be cultured in seawater [9][10][11]. The marine species of C. pyrenoidosa could possibly decrease the large inputs needed to a greater extent than freshwater species, because of the requirement of fresh water.…”

Chlorella pyrenoidosa is an excellent source of protein, and in this research, we assessed the antioxidant and emulsifying effects of Chlorella protein hydrolysate (CPH) using neutral proteases and alkaline proteases, as well as the properties of CPH-derived krill oil-in-water (O/W) emulsions. The CPHs exhibited the ability to scavenge several kinds of free radicals, including 1,1-diphenyl-2-picrylhydrazyl (DPPH), O2−, hydroxyl, and ABTS. Additionally, the CPHs (5 mg/mL) scavenged approximately 100% of the DPPH and ABTS. The CPHs showed similar emulsifying activities to Tween 20 and excellent foaming activities (max FS 74%), which helped to stabilize the krill oil-in-water emulsion. Less than 10 mg/mL CPHs was able to form fresh krill oil-in-water emulsions; moreover, the CPHs (5 mg/mL) in a krill O/W emulsion were homogenous, opaque, and stable for at least 30 days. Based on their inhibitory effects on the peroxide value (POV) and thiobarbituric acid reactive substances (TRABS), the CPHs were found to be able to inhibit lipid oxidation in both emulsifying systems and krill O/W emulsions. Thus, the CPHs could improve superoxide dismutase (SOD) activities by 5- or 10-fold and decrease the high reactive oxygen species (ROS) level caused by the addition of H2O2 in vitro. In conclusion, health-promoting CPHs could be applied in krill oil-in-water emulsions as both emulsifiers and antioxidants, which could help to improve the oxidative and physical stability of emulsions.
