摘要
多项研究证明，磁场处理对蓝藻培养物产生次生化合物的效率、发育和整体状况有积极影响。因此，本研究的主要目的是评估不同磁场（30 和 60 mT，21 天）对从 Desmonostoc alborzicum 提取的藻蓝蛋白（PC）生物活性的影响。结果表明，30 mT 的磁场提高了 PC 的浓度和纯度。然而，暴露在 60 mT 磁场中的 PC 的抗氧化、抗菌和抗真菌活性最高（p<0.05）。然而，SDS-PAGE 凝胶结果显示，与对照组相比，经 30 mT 磁场处理的 PC 中的α和β亚基的含量分别增加了 1.4 倍和 1.6 倍。总之，与 30 mT 相比，60 mT 磁场对 PC 的生物活性最高。
Studying the effect of magnetic fields on biological activity of phycocyanin extracted from Desmonostoc alborzicum
Multiple studies have provided evidence of the positive effects of treatment with magnetic fields on the efficiency of producing secondary compounds, development, and the overall condition of cyanobacteria cultures. Therefore, the main objective of this study is to evaluate the impact of different magnetic fields (30 and 60 mT for 21 days) on the biological activity of phycocyanin (PC) extracted from Desmonostoc alborzicum. Results showed that a 30 mT magnetic field had increased the concentration and purity of PC. However, the highest antioxidant and antibacterial and antifungal activity was found in the PC exposed to 60 mT magnetic field (p<0.05). However the results of SDS-PAGE gel showed that the amounts of alpha and beta subunits of PC treated with magnetic fields of 30 mT rose by 1.4 and 1.6 times, respectively, compared to the control. In conclusion, applying a 60 mT magnetic field could have the highest biological activity for PC in comparison to 30 mT.
