Effect of Blue Light Irradiation on Fucoxanthin Content in Phaeodactylum tricornutum

摘要(Abstract):

为了提高具有抗氧化、抗炎、抗肥胖等多种生物活性的天然类胡萝卜素岩藻黄素的产量,采用单因素实验法,探索不同光照强度、照射时间的蓝光照射条件对模式硅藻三角褐指藻Phaeodactylum tricornutum细胞生长、岩藻黄素含量及产量的影响。结果表明:经光合光子通量密度为10 μmol/(m2·s)的蓝光照射6 h,处于稳定期的三角褐指藻细胞密度无明显变化,但岩藻黄素含量较未处理组的提高了22.4%,岩藻黄素产量提升了23.9%;短时间的低光照强度蓝光照射能够显著促进三角褐指藻细胞生长,提高岩藻黄素含量。
