Two common freshwater algae Microcystis aeruginosa and Scenedesmus obliquus were employed as test organism to evaluate the toxic effects of the widely used antibiotic, cefradine. In general, cefradine had significantly toxic effect on population growth and chlorophyll-a accumulation of two algae and the cyanophyceae was more sensitive than the chlorophyceae. In addition, cefradine UV light degraded products had adverse effect on M. aeruginosa's growth and chlorophyll-a accumulation. In comparison, even if S. obliquus had growth ability when exposed to cefradine UV light-degradation products, the algal photosynthesis function was also disrupted.
两种常见的淡水藻类——铜绿微囊藻和斜生栅藻被用作测试生物，以评估广泛使用的抗生素头孢拉定的毒性效应。一般来说，头孢拉定对两种藻类的种群生长和叶绿素 a 积累有显著的毒性作用，而蓝藻比绿藻更敏感。此外，头孢拉定的紫外光降解产物对铜绿微囊藻的生长和叶绿素 a 积累有不良影响。相比之下，即使斜生栅藻在暴露于头孢拉定的紫外光降解产物时仍有生长能力，藻类的光合作用功能也被破坏了。
