【摘要】：分別用純培養(yǎng)與模擬培養(yǎng)法考察不動(dòng)桿菌LM1與假單胞菌LY1組成的復(fù)合菌對(duì)17β-雌二醇(E2)的協(xié)同降解特性.結(jié)果表明:當(dāng)細(xì)胞數(shù)量比為1時(shí),復(fù)合菌對(duì)E2的降解率分別為菌株LM1和LY1單獨(dú)作用的2.2倍和2.6倍,降解過(guò)程中菌株LM1和LY1的細(xì)胞數(shù)量比趨于1;在28℃,150r/min條件下培養(yǎng)7d后,復(fù)合菌對(duì)初始質(zhì)量濃度為1,5,10,20mg/L的E2降解率分別為99.6%,97%,93%,85%;當(dāng)培養(yǎng)基中氯化鈉添加的質(zhì)量分?jǐn)?shù)為3.5%時(shí),復(fù)合菌對(duì)E2的降解率顯著下降(p0.05);在25℃時(shí)復(fù)合菌對(duì)雞糞、豬糞及土壤樣品中E2的降解率分別為對(duì)照組的2.7,3.0,2.8倍.即由菌株LM1和LY1組成的復(fù)合菌可通過(guò)協(xié)同作用降解E2.
[Abstract]:The synergistic degradation of 17 尾 -estradiol (E _ 2) by acinetobacter LM1 and Pseudomonas LY1 was investigated by pure culture and simulated culture respectively. The results showed that when the cell number ratio was 1, the degradation rate of E2 was 2.2 times and 2.6 times of that of strain LM1 and LY1, respectively, and the ratio of cell number of strain LM1 and LY1 tended to be 1 in the process of degradation. After incubation at 28 鈩，
