摘要:	[1]研究計畫背景/緣起：隨著全球環保意識高漲，沼氣的利用性日益重要且已被視為未來再生能源的一種。根據資料顯示，台灣的沼氣資源相當豐富，但往往因為其存在高比例的CO2使得它的燃燒性不佳，加上現行的CO2分離方法多有耗能與操作程序複雜的缺點，使得沼氣常被不當排放而造成能源浪費及空氣污染的問題。在二氧化碳處理技術方面，透過微藻的光合作用來分解CO2並因此產出生質能源是目前最符合環保以及經濟效益的方法。然而，過程中所牽涉到的氣體包含甲烷以及氧氣等各自都會對微藻生長產生不利的影響，這使得微藻所能發揮的經濟效益受到限制。為了克服此一問題，國立中央大學生醫科學與工程系協同宇格材料企業有限公司共同提出利用全氟碳化物優良的CO2吸收效能，建構ㄧ可同時用於沼氣純化與優化微藻生物質及其衍生經濟產物產能之多效全氟碳光生物反應器系統(Perfluorinated Photo-Bio-Reactor System；PPBRS)。基於後續產業應用之考量，本計畫使用高經濟價值的擬球藻(Nannochloropsis oculata,)來作為測試該反應器效能的標的細胞。藉由本計畫的執行，我們預期除了提供一高效的沼氣純化與微藻細胞養殖技術以外，更期許能帶動國內相關環保、能源以及生技產業的發展，在創造更高的產業利益之餘，亦能達成綠色能源發展與落實節能減碳的目標。[2]計畫特點：本計畫中所建構的PPBRS之特點與預期可解決的問題分述如下:1)不同於傳統僅將CO2提供給植物行光合作用以達成環保的目的，本系統同時兼顧並有效提升微藻生長及其經濟產物生產之效能；2)全氟碳化物本身具備高度CO2吸附性以及極端惰性，因此能夠改善傳統用胺類作為吸附劑方法上耗能與程序複雜的問題；3)在本系統中微藻與沼氣不會直接接觸，以此可避免甲烷對細胞毒性與甲烷接觸氧氣易爆炸的顧慮；4)全氟碳化物在本系統設計上總量恆定，並且可以重複使用，符合產業應用的成本考量，同時也不會有因排放而造成環境污染的問題。[3]計畫執行優勢：本計畫主持人在全氟碳化物生物工程應用技術上有長期的研究發展，並對於擬球藻光生物反應器設計上有產學研發之實務經驗。合作廠商/宇格材料企業有限公司熟稔市場上各類動/植物細胞養殖技術，並對於計畫中所述的反應器系統各單元氣體量測與微藻養殖與脂質分析具備專業知識與完整技術支援能力。因此該研究組合足以執行此產學合作計劃案。 ;[1] Background: With growing awareness of global environmental protection, biogas has been recognized as one of critical renewable energy in the world. In fact, the resources of biogas in Taiwan are quite rich, however, their applicability is generally low due to high proportion of CO2 included. Furthermore, since the procedures in most of current CO2 isolation methods are labor- and energy-consuming, the biogas is often exhausted inadequately and thus led to energy waste and air pollution issue accordingly. In terms of the strategies of CO2 isolation, using microalgal photosynthesis to break down CO2 and thereby produce bioenergy is generally thought as the most green and cost-effective approach. However, the gas involved in the aforementioned biogas-microalgae system, including CO2, CH4, and O2, may cause adverse effects on microalgal growth. Therefore, developing a method which can effectively isolate CO2 from biogas and further use the extracted CO2 to benefit productions of biomass and bioenergy of microalgae is urgently needed. To meet the aforementioned goal, a novel perfluorocarbon (PFC) photobioreactor System (PPBRS), which enables biogas purification and can simultaneously enhance the yields of microalgal biomass and the derived economic products, is developed in this study. Considering the subsequent applications in industry, the effectiveness of the PPBRS is verified by using the high economic value of microalgae Nannochloropsis oculata as the model cell. Through the implementation of this project, we expect that besides providing an efficient methodology for biogas purification and microalgal cultivation, we can further promote the development of environmental protection, energy and biotechnology industries in Taiwan.[2] Advantages: The merits of the developed PPBRS are described in the following: 1) Unlike traditional methods that CO2 is just simply transformed by plant photosynthesis and that can merely meet the goal of environmental protection, the developed PPBRS can not only perform the CO2 separation from biogas, but also enhance the productions of microalgal biomass and biolipids that are highly advantageous for industrial use. 2) Based on the characteristic of PFC that it is highly CO2 absorbable and extremely inert, the developed PPBRS may be able to avoid and/or ameliorate drawbacks of energy-consuming and/or complicate procedures occurred in the traditional adsorbent-based methods. 3) Since the biogas will not directly contact with microalgae during PPBRS operation, the concerns of cytotoxicity of methane to microalgae and explosive risk due to oxygen-methane reaction can be neglected. 4) The PFC inside the system is able to be maintained and recycled that offer the advantages of cost-effective and environmental friendly to PPBRS for use in industry.[3] Qualification/Capability: The project PI (YH Lee) has robust research background in the fields of bioengineering and PFC-based material engineering, and has practical hands-on experience on microalgal photobioreactor design and manufacture in the past 5 years. The partner company; Yu Green Co. Ltd., is a well-established biotech/material company with strong professions in cell culture technology, gas detection techniques, and instrumental analysis of chemicals. Therefore, such partnership is perfectly qualified to conduct this industry-academia collaboration project.
