中文摘要	本計畫研究以藻類培養來固定煙氣中之CO2，期使以創新研發技術拓展以微藻來固定工業煙氣，達到減少碳排放之目的。首先篩選本土五種藻種，選擇高和中溫之藻種以進行試驗，以找出高效和具備後續經濟利用價值之藻種作為試驗對象。試驗藻種包括淡水和海水藻種，經核酸定序結果確定藻種為淡水種：Synechococcus #CS1、Cyanidioschyzon #YM1、Chlorella #AS8；海水種Dunaliella #KP1、Chlorella #AS6。試驗結果確定Synechococcus #CS1(最適溫50°C)及Chlorella #AS8(最適溫35°C)為最適合於處理煙氣之預選藻種。實際模場試驗中，環境溫度在低於35°C以下，Chlorella #AS8較Synechococcus #CS1表現為佳，高於40°C則以後者為佳。由Chlorella #AS8之生長曲線，在30°C下之收成時間為6天，約可達0.15 g L-1，但此產能隨起始藻濃度而定。本計畫從試驗中確定各種主要營養鹽的需求濃度。在實廠應用上可用微藻生產控制系統整合多組微藻光合反應器之方式，搭配穩定之溫度控制及補光系統，提升本系統之產能。在藻類商品經濟效益上，初期以直接當作魚蝦飼料之用途為宜，長遠效益則以開發成食品或藥用為佳。國內對於微藻之應用發展研究尚屬初步，對於煙氣回收之研究、光合反應器之研發及藻種資料庫之建立等都需要有較長期之研發和經費支持，才能實現煙氣微藻減碳之目標。

摘要	In this project, novel technology for using microalgae to fix CO2 in industrial flue gas was developed. Five local species of microalgae, including both from fresh and salt water origins, were screened under high- and medium-temperature culture conditions. The species identified by DNA sequencing were Synechococcus #CS1, Cyanidioschyzon #YM1, Dunaliella #KP1, Chlorella #AS8, and Chlorella #AS6. After a series of tests, Synechococcus #CS1 and Chlorella #AS8 were identified to be the potential organism, which grew optimally at 50°C and 35°C, respectively. Under temperature below 35°C, Chlorella #AS8 exhibited a higher growth rate than Synechococcus #CS1, whereas a lower rate when above 40°C. Under such condition, a maximum biomass of about 0.15 g L-1 at day 6th of incubation was obtained. However, the magnitude of biomass varied with the initial concentration of algae used for cultivation. From experiments, the basic requirement of macro-nutrients for getting algal biomass was calculated. For mass production, an integrated system, combining photoreactors with a stable temperature controller and illumination was proposed. Basically, the harvested algal biomass can be used as fish or shrimp meal. However, a further study of potential usage of algal biomass for health food or pharmaceutical purpose should be done. Basing on the present study, six suggestions are proposed for further exploiting the utilization of algae in order to optimize CO2-fixation of flue gas in Taiwan.
