摘要/Abstract

摘要： 为了研究不同营养条件对二形栅藻生长及生化组分的影响，本研究设置了3种不同的培养条件(BG11、BG11+DW、DW)进行研究。结果表明：二形栅藻在两阶段法(BG11+DW)培养下的生物质产率、总碳水化合物和总脂含量均最高，分别达到了0.045 g/(L?d)、37.4 μg/mL和305.0 μg/mL。3种不同培养条件下二形栅藻的脂肪酸组成相似，以C16和C18脂肪酸为主，饱和脂肪酸和单不饱和脂肪酸含量均在80%以上，特别是在两阶段法培养下，其含量达到了90.73%，表明二形栅藻是生物柴油生产的合适原料。

Abstract: In order to investigate the effect of different nutritional conditions on the growth and the lipid properties of Scenedesmus dimorphus, 3 kinds of cultivation conditions (BG11, BG11+DW, DW) were used in this research. The results showed that the optimal status of biomass production rate, total carbohydrate and total lipids were achieved by 0.045 g/(L?d), 37.4 μg/mL and 305.0 μg/mL under two-phase cultivation (BG11+DW) of Scenedesmus dimorphus. Moreover, a similar fatty acid composition of Scenedesmus dimorphus was attained through 3 ways of cultivation, and there was a dominance of C16/C18 fatty acid groups (more than 80%) which was composed of saturated and monounsaturated fatty acid. Especially, under two-phase cultivation it would elevate to 90.73%. With these desirable lipid properties, Scenedesmus dimorphus would be highly suitable candidates for biodiesel production.
