| 摘要: |
| 结合青岛地区不同季节室外温度变化特点, 采用熵权法对9 株微藻利用发电厂废气生产生物柴油的户外开发潜力进行评估。选取油脂产率、油脂组成、CO2 耐受性、破壁难易度和温度适应性5 项指标, 根据实验室测得的数据进行计算, 得出春冬季以上5 项指标的权重分别为0.261、0.002、0.059、0.211 和0.467, 而夏秋季以上5 项指标的权重分别为0.098、0.001、0.022、0.079 和0.801。在此权重的基础上, 得出在春冬季节开发潜力最大的藻株为微拟球藻(Nannochloropsis sp. ZL-12),在夏秋季节开发潜力最大的藻株为球等鞭金藻(Isochrysis galbana C5001)。本方法为户外大规模开发生物柴油的微藻藻种选择提供了一个有效的思路。 |

| Abstract: |
| Combined with outdoor seasonal temperature variation in Qingdao, East China, we evaluated in entropy weight theory on nine microalgae for possible outdoor large-scale biodiesel production making use of discharged CO2 from local power plants. Five indicators including oil yield, oil composition, CO2 tolerance, difficulty of breakage, and temperature adaptability were selected to calculate the entropy weight based on laboratory measurements. Weights for the above five indicators in spring and winter were 0.261, 0.002, 0.059, 0.211, and 0.467, while in summer and autumn were 0.098, 0.001, 0.022, 0.079 and 0.801, respectively. Therefore, microalgae in maximum potential for large-scale biodiesel production in spring and winter could be Nannochloropsis sp. ZL-12, while in the summer and autumn the Isochrysis galbana C5001. The method provides an effective way for microalgae strain selection for outdoor large-scale biodiesel production. |
