摘要：

摘要：跟踪检测了六种海洋微藻在生长过程中单位细胞β-葡聚糖的含量变化，分析了其累积时期、累积速率以及提取制备的得率和纯度，并对几种微藻来源的β-葡聚糖进行了免疫活性检测。结果显示，β-葡聚糖在微藻种群增殖的平台期累积量最大，不同种类的微藻细胞累积β-葡聚糖能力差异较大，本研究中，假微型海链藻(Thalassiosira pseudonana)具有较大的累积速率、提取制备得率以及较大的免疫活性。六种海洋微藻来源的β-葡聚糖都显示比酵母来源的β-葡聚糖免疫活性高。

Abstract:

The accumulation features of microalgal β-glucans, including accumulation phase and rate, have been characterized by monitoring the contents of β-glucans from six marine microalgae during their growth cycles, the extraction and the immuno-stimulative effects of β-glucans were also studied. The results indicated that the contents of cellular β-glucans reached maximum at stationary phase for all the microalgae, however, with large variations depending on the species. Among the six microalgae, Thalassiosira pseudonana showed outstanding features for its β-glucans with high accumulation rate, isolation yield, and significant immuno-stimulative effects. It is also showed that the immuno-stimulative effects of β-glucans were higher from microalgae than that from yeast.
