研究了紫外线对微藻生长、生物量、脂质积累和生物柴油特性的影响。将微藻菌株 Chlorella sorokiniana UUID6 在 LED 灯（对照）下培养 14 天，并在光周期中间将微藻暴露于 UV 光（280-320 nm）3 天。采用分光光度计和细胞计数分析微藻的生长速率，采用改进的尼罗红法分析油脂积累情况。结果表明，经紫外线处理的微藻藻细胞生长缓慢。经紫外线处理的藻细胞的 FAME 谱主要含有十六烷酸 (C16)、硬脂酸 (C18) 脂肪酸。与对照组相比，经紫外线处理的细胞中 PUFA 的含量非常少。
The effect of UV light on growth, biomass, lipid accumulation and biodiesel properties of microalgae was studied. A Microalgae strain Chlorella sorokiniana UUIND6 was cultivated for 14 days as under LED light (Control) and microalgae were exposed to UV light (280-320 nm) in the middle of the photoperiod for 3 days. The growth rate of microalgae was analyzed by spectrophotometer and cell counting, while oil accumulation was analyzed by improved Nile red method. Results showed that microalgae under UV light treated algal cells showed less growth. FAMEs profile of UV treated algal cells mainly contains hexadecanoic acid (C16), stearic acid (C18) fatty acids. PUFA found in very less amount in UV treated cells as compared to control.
