| 为检测鸡饲料和鸡粪中雌激素，优化其微生物降解条件，应用高效液相色谱（HPLC）法检测蛋鸡饲料和鸡粪中的雌激素，利用11种高效降解雌激素的单一菌株和等体积混合得到的菌群开展雌激素的降解实验。结果表明：只有蛋鸡鸡粪中含有雌二醇（E2），含量为230 ng·g-1。微生物菌群的降解率高于单一菌株，在27℃下，10 d内能够降解76%的E2。研究表明，蛋鸡鸡粪中有雌激素存在，微生物菌群对雌激素的降解率高于单一菌株。 |
| 英文摘要: |
| To detect estrogen and degrade it, estradiol(E2) in laying hens feeds and feces were detected by high performance liquid chromatography(HPLC). Eleven bacterial strains that exhibit high degradation against estrogen and bacterial groups mixed by the same volumes of 11 bacterial strains were chosen to study estrogen degradation. The results showed that E2 was found only in laying hens feces. The content of E2 was 230 ng·g-1. The results showed that bacterial groups had the higher degradation efficiency than single bacteria, and could degrade 76% E2 in 10 d at 27℃. Our results indicated that there was estrogen in laying hen feces, and E2 degradation efficiency of the bacterial group was higher than single bacteria. |
