| 摘要: |
| 类菌孢素氨基酸(mycosporine-like amino acids, 间称MAAs)存在于许多生物体内,对紫外辐射(UVR)有较高的吸收能力,被认为有保护细胞、减少UVR损伤的功能. 通过对从太湖分离、室内培养的铜绿微囊藻和以微囊藻为优势种类的太湖浮游植物样品的吸收光谱和反相高效液相色谱分析,发现铜绿微囊藻和太湖浮游植物都含有shinorine和porphyra-334两种MAAs,但以shinorine为主. 本文还讨论了MAAs与铜绿微囊藻水华形成的关系. |

| Abstract: |
| Mycosporine-like amino acids (MAAs) strongly absorb UVR and protect cells against harmful UVR. Using spectroscopic and HPLC analysis, two MAAs were detected, i.e. shinorine and porphyra-334, in the pure culture of Microcystis aeruginosa isolated from Lake Taihu and in the phytoplankton samples of Lake Taihu dominated by Microcystis. Synthesis of MAAs could be one of the adaptive strategies to high solar radiation including UVR and one of the bloom-forming mechanisms in Microcystis aeruginosa. |
