“…The growth of algae depends on many factors and can be optimized in terms of temperature, sunlight utilization, pH control, composition of solution, fluid mechanics, etc. [11][12][13][14], in which controlling the solution condition is more significant in the growth of algae. Using NaOH alkaline solution, the CO 2 gas can be absorbed and dissolved as carbonate solution depending on the pH range.…”

The capture of CO2 by means of a microalgae culture solution was explored in a continuous bubble‐column scrubber under a constant pH environment. Optimum conditions for a pilot‐scale study were evaluated. With the Taguchi method, a total of sixteen runs were required. Absorption rate, absorption efficiency, overall mass transfer coefficient, and gas‐liquid flow rate ratio were determined by a material balance model and a two‐film model under steady‐state conditions. From the signal‐to‐noise ratio, the sequence of parameters could be stated. Uncontrolled experiments were also performed and empirical equations were discussed.

“…It is effective for capturing and adsorbing atmospheric CO2 (Sayre 2010;Moreira and Pires 2016). The existence of algae in the aquatic ecosystem serves as a controller of CO2 released into the air, because it rapidly converts CO2 into organic material through photosynthesis unlike terrestrial plants (Jeong et al 2003). The efficiency of microalgae to convert CO2 during photosynthesis ranges from 10-29% while terrestrial plants are from 1-2%, however, some types of microalgae are able to increase their biomass within 3.5 hours (Chisti 2007).…”

“…The efficiency of microalgae to convert CO2 during photosynthesis ranges from 10-29% while terrestrial plants are from 1-2%, however, some types of microalgae are able to increase their biomass within 3.5 hours (Chisti 2007). The fastest-growing microalgae are Chlorella pyrenoidosa with 1.17 optical density per five days (Jeong et al 2003). It is a phototrophic microorganism with simple nutritional requirements and also acts as a primary producer (Singh and Ahluwalia 2013).…”

Abstract. Widigdo B, Rifqi M, Mashar A, Nazar F, Wardiatno Y. 2020. The contribution of phytoplankton in the carbon adsorption and stock during shrimp culture in brackishwater ponds. Biodiversitas 21: 5170-5177. In environmental point of view, it is important to determine the potential of adsorption and stock of blue carbon during shrimp farming in ponds with three cultivation technologies namely: extensive/traditional, semi-intensive, and intensive. The aquatic primary productivity approach is used to measure the potential of carbon adsorption in shrimp ponds, while the carbon conversion of chlorophyll-a content is used to measure its stock. The primary productivity and chlorophyll-a content were measured using three ponds for each cultivation technology every ten days from stocking (DOC 0) until the harvest period. The sampling location is in the BLUPPB shrimp pond area of Karawang, West Java - Indonesia. The study concluded that the adsorption and stock of blue carbon varied during shrimp farming in ponds. The primary productivity and chlorophyll-a content of the three cultivation technologies were the significant difference as the results of ANOVA Single Factor. Carbon adsorption average during extensive/traditional, semi-intensive, and intensive shrimp farming in ponds was 1.912832 g C m-3 day-1, 7.097145 g C m-3 day-1 and 8.250195 g C m-3 day-1, respectively. While, the average carbon stock during shrimp farming in extensive/traditional, semi-intensive, and intensive ponds were 0.64896 g m-3, 14.97473 g m-3, and 25.11102 g m-3, respectively.

“…Existing ligands, such as the carboxyl group or other functional groups in the cell wall of the algae, cause that cation to be absorbed. As a result, a negative charge is generated and the attraction between the negative charge and the cation increases the absorption on the cell surface and ultimately reduces the cation in the environment [51][52][53].…”

Nowadays, due to augmentation of population and expansion of cities and the limitation of fresh water sources in the world, existing water resources cannot meet the human needs. Desalination or reduction of salinity of water through biological methods involves the use of plant species, microorganisms, algae or a combination of them, which can be effective in reducing water salinity. The objective of this study was to investigate the desalination of saline waters by using Dunaliella salina algae. For this purpose, the experiments were carried out as factorial based on completely randomized design. The expected tests were conducted in a laboratory controlled condition for humidity, light and temperature (90 days). During this research, the Electrical Conductivity (EC) was measured daily. The results showed that salt absorption in Dunaliella salina algae was significantly different. High salt absorption was observed in Dunaliella salina at a concentration of 130mS.cm-1. Due to the constant humidity, light and temperature, salt removal from saline water was observed in laboratory conditions. The results of this study indicate that significant reduction of chlorine, sodium and bicarbonate levels were observed using Dunaliella salina algae. According to the results of this study, it seems that reducing salt absorption in algae is due to the use of salt in the metabolism and the growth and proliferation of algae. The absorption process in this study showed that the catch of Dunaliella salina has a good ability to remove salt and can be used as an appropriate suggestion for salt removal from saline water.
