尿苷二磷酸葡萄糖促进三角褐指藻岩藻黄素积累的研究
Studies on the Promotion of Fucoxanthin Accumulation by Uridine Diphosphate Glucose in Phaeodactylum tricornutum
摘要
Abstract
Fucoxanthin is an abundant carotenoid in nature,but its content is low.In order to increase the content of fucoxanthin,the effects of different concentrations of exogenous UDPG on the photosynthetic capacity and fucoxanthin content of Phaeodactylum tricornutum were investigated in this experiment with chlorophyll fluorescence parameter method and high-performance liquid chromatography.The results showed that 150 μmol/L of UDPG significantly improved the photosynthetic capacity and promoted the accumulation of fucoxanthin in P.tricornutum.The fucoxanthin content reached(9.57±0.81)mg/g,161.76％higher than that of the control.In addition,the contents of diadinoxanthin,diatoxanthin,β-carotene,violaxanthin,chlorophyll a and chlorophyll c2 were increased by 84.31％,79.73％,164.74％,123.04％,358.35％and 2 260.09％compared with that of the control,respectively.It was found for the first time that exogenous addition of UDPG significantly promotes the accumulation of fucoxanthin in P.tricornutum.关键词
