摘要

本研究螺旋藻構造簡單，與其他藻類比較，具高葉綠素含量、生長週期短、光合作用高；另外，螺旋藻具有生質油源、二氧化碳減量、生物化學品（DHA）、生物放電等高附加價值特點。本研究探討螺旋藻培養的溫度、氮源對螺旋藻成長之影響，長時間生物放電能力；由實驗設計法中找尋螺旋藻最佳培養條件。由實驗結果得到最佳培養條件為：使用ZARROK培養基14.68 g/L（含0.125g/L尿素、3.125g/L NaNO3）、30°C、40W日光燈照射下，每50mL螺旋藻，收集生物量（biomass）為0.554g/L；7h放電過程，可收集總庫侖為0.42 C、電壓維持在0.26 V。由實驗結果可知，利用螺旋藻進行光合燃料電池的應用，深具可行性。

In this study, Spiruling platensis has simple structure compared with other algae, high content of chlorophyll, short growth cycle, and strong photosynthesis. Moreover, Spiruling platensis has some high value-added characteristics of having biomass oil source, reduction of carbon dioxide, Docosahexaenoic Acid (DHA), and bio-discharge. The research explores the effects of cultivation temperature of Spiruling platensis and source of nitrogen on growth of Spiruling platensis, the long-term biological discharge ability, and finding the optimal culture condition of Spiruling platensis through various designs of experiments. The result shows that the optimal culture conditions as follows : adding 1.48 g/L ZARROK plate media which contains 0.125 g/L Urea and 3.125 g/L NaNO3 under the condition of 30℃ and 40 watt irradiation of fluorescent lamps, the biomass of 0.554 g/L is collected per 50 mL Spiruling platensis. In the process of discharge for 7 h, the total Coulomb of 0.42 C is collected and the voltage is kept in 0.26 V. Consequently, the result shows that the application of photosynthetic fuel cell is high feasible by using Spiruling platensis.
