不同水平维生素E对小球藻生理过程的影响研究

Research on the Effects of Different Levels of Vitamin E on the Physiological Processes in Chlorella Vulgaris

摘要: 维生素E是一种脂溶性维生素，在各种生物体的生长与繁殖中起到不可或缺的作用。为比较不同水平维生素E对小球藻生长等方面的影响，本研究以小球藻作为试验对象，在相同培养条件下，向培养液中添加0 mg/L、10 mg/L、25 mg/L、50 mg/L、100 mg/L的维生素E母液，探究其对小球藻生长、内部VE合成含量、色素含量、最大光化学效率的作用效果。结果表明，在培养液中加入适量的维生素E，可对小球藻的生长起到促进作用，在培养条件相同的情况下，浓度为25 mg/L的维生素E生长效果最好且25 mg/L试验组的VE合成含量及最大光化学效率显著高于其余四组(P < 0.05)。未来可通过探索维生素E与不同营养物质间的最佳配比，以望开发出促生长效果更佳的复合营养强化剂，为小球藻的大规模培养和应用提供更具优化性的营养方案。

Abstract: Vitamin E is a fat-soluble vitamin that plays an essential role in the growth and reproduction of various organisms. This study aimed to compare the effects of different concentrations of vitamin E on the growth and other characteristics of Chlorella vulgaris. Under controlled culture conditions, vitamin E solution at concentrations of 0 mg/L, 10 mg/L, 25 mg/L, 50 mg/L, and 100 mg/L were added to the culture solution to investigate their effects on growth, internal vitamin E synthesis, pigment content, and maximum photochemical efficiency of Chlorella vulgaris. The results indicated that the addition of an appropriate amount of vitamin E to the culture solution could enhance the growth of Chlorella vulgaris. Specifically, a concentration of 25 mg/L of vitamin E yielded the most significant growth effects, with the vitamin E synthesis content and maximum photochemical efficiency in the 25 mg/L group being significantly higher than those in the other four groups (P < 0.05). Future research will focus on exploring the optimal ratio of vitamin E to various nutrients, with the goal of developing compound nutrient enhancers that promote growth more effectively and provide improved nutritional solutions for the large-scale cultivation and application of Chlorella vulgaris.
