| 摘 要： | 塔玛亚历山大藻(Alexandrium tamarense)是一种有毒甲藻,常引发赤潮,对海洋环境及人类健康造成极大的威胁.前期研究发现,耐辐射球菌属的一株细菌Y35能够通过分泌杀藻化合物Deinoxanthin达到控制塔玛亚历山大藻生长的效果.为了加强Deinoxanthin的应用效果,对其在不同条件下的稳定性进行了研究.结果表明,杀藻化合物Deinoxanthin有较高的热稳定性,且在中性和碱性条件下稳定,在光照和紫外线辐射下易分解.而通过壳聚糖和海藻酸钠对Deinoxanthin进行包埋固定化,从而构建缓释微球提高了Deinoxanthin的稳定性.杀藻制剂能够高效地表现出杀藻效果,杀藻制剂的研发为杀藻细菌色素应用于藻华治理奠定了基础.

| Abstract: | Alexandrium tamarense is a toxic dinoflagellate, capable of forming harmful algal blooms (HABs), and poses a substantial threat to both the marine environment and human health. Our previous research found Deinococcus sp. Y35 could secret algicidal pigment deinoxanthin which showed efficient algicidal effect on A. tamarense, resulting in controlling the growth of A. tamarense. In order to enhance the algicidal effect of deinoxanthin, the stability of deinoxanthin under different conditions was investigated. The results show that the thermal stability of deinoxanthin was high and remained stable under neutral and alkaline conditions, yet was prone to decompose in the light and ultraviolet radiation. The stability of deinoxanthin was improved after immobilization by chitosan and sodium alginate. The algicidal agent could exhibit high algicidal effect on A. tamarense, laying the foundation for the application in the control of HABs. |
