was cultured in different light path length under different incident light intensity to investigate the effect of light on alga growth as well as hydrocarbon and fatty acid accumulation. Results indicated that longer light path length required higher incident light intensity in order to meet the light requirement of algal growth and hydrocarbon accumulation during the course of cultivation. However, hydrocarbon profile was only affected by the incident light intensity and not influenced by the light path length. High incident light intensity enhanced the accumulation of hydrocarbons with longer carbon chains. Besides, the fatty acid content and profiles were significantly influenced by both incident light intensity and light path. Higher fatty acid content and higher percentage of C18 and monounsaturated fatty acid components were achieved at the higher incident light intensity and lower light path length. Taken together, these results are benefit to improve its biomass and oil productivity through the optimization of light and photobioreactor design.
在不同入射光强度下于不同光程长度进行培养，以研究光对藻类生长以及碳氢化合物和脂肪酸积累的影响。结果表明，在培养过程中，为满足藻类生长和碳氢化合物积累的光照需求，较长的光程长度需要更高的入射光强度。然而，碳氢化合物谱仅受入射光强度影响，不受光程长度影响。高入射光强度促进了长碳链碳氢化合物的积累。此外，脂肪酸含量和谱图均受入射光强度和光程的显著影响。在较高入射光强度和较短光程长度条件下，可获得更高的脂肪酸含量以及更高比例的C18和单不饱和脂肪酸成分。综上所述，这些结果有助于通过优化光照和光生物反应器设计来提高其生物量和油脂生产率。
