The aim of this study was to investigate the effects of butylated hydroxytoluene (BHT) on the production of astaxanthin and lipids in Haematococcus pluvialis LUGU under high-light and nitrogen-deficiency conditions. Astaxanthin and lipid contents were increased by 71.13% and 10.71%, respectively, in algal cells treated with 2 mg L BHT. The maximal contents of astaxanthin and lipids were 3.17% and 46%, respectively. The levels of reactive oxygen species (ROS) in the presence of BHT were lower than in the control, and this effect involved strong activation of several antioxidases. Additionally, BHT application upregulated endogenous nitric oxide (NO) production. These results showed that this approach is useful for stimulating production of astaxanthin and lipids in H. pluvialis and that exogenous BHT induces astaxanthin and lipid production, which is responsible for the signalling molecule responses against abiotic stress conditions in H. pluvialis.
本研究旨在探讨丁基羟基甲苯（BHT）对高光和氮缺乏条件下雨生红球藻生产虾青素和脂类的影响。用 2mg/L 的 BHT 处理藻类细胞后，虾青素和脂类含量分别增加了 71.13%和 10.71%。虾青素和脂类的最大含量分别为 3.17%和 46%。BHT 存在时活性氧（ROS）的水平低于对照，这种作用涉及几种抗氧化酶的强烈激活。此外，BHT 的应用上调了内源性一氧化氮（NO）的产生。这些结果表明，这种方法可有效刺激雨生红球藻生产虾青素和脂类，外源 BHT 诱导虾青素和脂类的产生，这是雨生红球藻应对非生物胁迫条件的信号分子反应的原因。
