“…Increase in light intensity of 5000-12,000 lux can enhance growth of diatoms, but the growth decreases when the light intensity exceeds 12,000 lux [80]. Light intensity of 4000-5000 lux is an optimum light intensity range for auxospore formation [39].…”

“…CO 2 uptake rates of microalgal cells could be stimulated by increase in CO 2 concentration in the media, and therefore culture without additional CO 2 would exhibit low CO 2 absorption rates, and although the pH of the culture seemed to increase, the pH never exceeded 8. In our previous study, [39] reported that the media pH varied from 7 to 8 which is considered sufficient for algal culture at laboratory scale.…”

The global warming issue caused mainly by carbon dioxide (CO 2 ) has triggered various efforts to reduce excess amount of CO 2 emitted into the atmosphere. A viable option is to utilize biomass production potential of microalgal consortium in aquatic ecosystem that constantly requires CO 2 to perform photosynthesis. This study aims to provide scientific contributions to the development of environmental studies, particularly of using microalgal consortiums as carbon capture and storage (CCS) agent by engineering their culture conditions. A number of studies analyzing biological reduction of atmospheric CO 2 by using CO 2 absorption capability of terrestrial plants have been facing many difficulties. Compared to various terrestrial plants, microalgae are generally considered photosynthetically more efficient. Exploitation of microalgal capability has numerous advantages, including their faster regeneration time, ability to grow in less space than terrestrial plants, and because the cultivation of microalgae can be done on a small-scale or large-scale operation, under controlled conditions, and is independent to climatic changes. Taking into account long-term advantages, this study is a preliminary study which is expected to be able to provide information and feedback regarding integrated microalgal culture system that may lead to alternative solutions of ecofriendly and sustainable environmental management technology that are capable of mitigating environmental problems caused by CO 2 (as greenhouse gas) emissions. Hence, the results of this research could be implemented by building urban microalgal ponds in efforts to develop sustainable cities in terms of CO 2 emission reduction in urban areas.

“…The microalgal cells were cultured in PHM (Phovasoli Haematococcus Media) artificial medium, which was prepared as follows (per litre was flowed continuously at a flow rate 7L.day and the detention time of 3.8 days. Four fluorescent lamps were positioned outside the photo-bioreactor to obtain light intensity of 4000 lux, set for 16 hours light exposure and 8 hours dark with operating temperature of 30°C maintained during the study (Rinanti et al 2014). Three compositional variations of microalgae consortium were used.…”

“…Although, study for it as potential for CCS were limited. One study reported that A. falcatus grew in a specialized PHM medium able to havecarbon removal rate of 20% utilizing a 2% CO 2 feed gas stream [10]. A. falcatus has reported to contain a lipid of more than 35%, optimal growth length of 0.20 μm and a biomass productivity of 7.9 mg/L-day in a BG-11 medium [8].…”

Abstract. This study evaluates the performance of alkaliphilic microalgae Ankistrodesmus falcatus in the Bicarbonate-based Integrated Carbon Capture and Algae Production System (BICCAPS). The system utilized bicarbonate as carbon source for microalgae production. BICCAPS parameters such as pH, algal biomass productivity and CO2 utilization (inorganic carbon conversion, Ci) were observed at different sodium bicarbonate (NaHCO3) loading concentration and type of culture media. The highest productivity was observed at 10 g/L of NaHCO3 loading in BRSP medium at 3.5539 mg/L/day. This value is 30% lower compared to the control experiment (continuously aerated bioreactor). The Ci values of the different system ranges from 1.17 x 10 -4 to 1.51 x 10 -4 moles/L/day. Both the pH of the BRSP and NPK media at 10 g/L and 30g/L loading of NaHCO3 increased through time. The result shows that A. falcatus has a potential in BICCAPS utilization.
