Carbon capture and storage (CCS) through biological approach has attracted much attention as global warming and climate change issue becomes a worldwide agenda. Energy production industry from coal in Malaysia produced 50.661 million metric tons of carbon dioxide in 2012, and the trend showed it will keep increasing year by year. CCS through biological approach can be done by microalgae which are versatile microorganism which perform photosynthesis process that can store CO2 in the biomass form. In this study, microalgae strains were isolated from the native environment nearby a coal-fired power plant, where samples were collected in different canal in which pre-treated flue gases are discharged. The microalgae strains were identified by both morphological and molecular approaches. Result from 18s rRNA gene sequencing showed that the isolated strains is Chlorella sp. with similarity 99% with Chlorella sp. SAG 211-18. The identified strains of microalgae then cultivated with three concentration of CO2 (ambient air, 1% and 5%) and the growth rate showed 0.4017 day -1 , 0.5752 day -1 and 0.4427 day -1respectively. Different concentration of CO2 (ambient air, 1% and 5%) showed that the isolated strains yielded 1.005gL -1 , 1.101gL -1 and 1.035gL -1 respectively. This study also showed that with different concentration of CO2, the sequestration rate is ranging from 1% to 4.3%.Keywords: microalgae, isolation, purification, DNA sequencing Abstrak Pemerangkapan dan penyimpanan karbon (CCS) melalui pendekatan biologi telah menarik minat pengkaji disebabkan masalah pemanasan dan perubahan iklim global. Pada tahun 2012 sahaja, Malaysia telah menghasilkan 50.661 juta ton metrik karbon dioksida hasil daripada penghasilan tenaga yang bersumberkan arang batu, dan tahun demi tahun penghasilan karbon dioksida dijangkakan akan terus meningkat. Pemerangkapan dan penyimpanan karbon melalui pendekatan biologi boleh dilakukan oleh mikroalga yang merupakan mikroorganisma unggul di mana ianya berupaya menjalankan proses fotosintesis dalam menukarkan karbon dioksida ke dalam bentuk biojisim. Dalam kajian ini, mikroalga dipencilkan daripada habitat asal yang merupakan terusan bagi air penyejuk untuk stesen janakuasa arang batu. Mikroalga yang diperoleh, dikenalpasti menggunakan kaedah pengecaman secara morfologi dan molekul. Hasil keputusan pengenal pastian molekul menggunakan kaedah penjujukan genom 18s rRNA mendapati, mikroalga yang berjaya dipencilkan adalah Chlorella sp. yang mempunyai persamaan sehingga 99% dengan Chlorella sp. SAG 211-18. Mikroalga yang telah menjalani proses identifikasi kemudiannya dikultur menggunakan 3 kepekatan karbon dioksida yang berbeza (CO2 pada udara persekitaran, CO2 1% dan CO2 5%) dan hasil menunjukkan kadar pertumbuhan masing-masing adalah 0.4017 hari -1 , 0.5752 hari -1 , dan 0.4427 hari -1 . Pada kepekatan CO2 yang berbeza (CO2 pada udara persekitaran, CO2 1% dan CO2 5%), hasil biojisim yang terkumpul daripada pengkulturan mikroalga masing-masing

“…According to the previous studies, CO 2 emissions from anthropic activities have accumulated in the atmosphere in excess of 800 Gigatons since pre-industrial times, and about 10.6 billion tons of CO 2 were discharged from the existing power plants, accounting for 40.6% of the total CO 2 emissions worldwide [10]. Among the current and potential uses, CO 2 capture is considered as an option to mitigate the emissions from power plants.…”

“…Under atmospheric pressure, CO 2 capture by alkanol amine, ammonia solutions or ILs has been widely studied and partially applied to industrial engineering [7][8][9]. Among the alkanol amine methods, mono-ethanolamine (MEA) is used most extensively, but the absorption efficiency of CO 2 is not high and the regeneration product is only CO 2 [10]. For the method of ammonia solutions, due to the high saturated vapor pressure and the fast evaporation rate, ammonia escape is becoming an important technical issue which causes secondary pollution and materials loss [10,11].…”

“…Statistically, a mass of CO 2 is derived from fossil fuel combustion of power plants; therefore, CO 2 emission reduction in power plants is necessary to deal with global climatic anomaly (Davison, 2007;Li et al, 2013;Shuangchen et al, 2013c). As a chemical absorbent among the acid air pollution removal technologies, ammonia solution has been applied in ammonia desulfurization and CO 2 capture such as ECO 2 of Powerspan Ltd., US, it has advantages of high removal efficiency and good adaptability for operating conditions (Bai and Yeh, 1997;Ma et al, 2014;Qin et al, 2010;Yeh and Bai, 1999). In recent researches, the regenerative CO 2 capture using ammonia solution is regarded as a feasible direction to reduce the CO 2 emission of power plants (Ciferno et al, 2005;Corti and Lombardi, 2004).…”
