Abstract:

In order to solve the difficult problem of treating fosfomycin pharmaceutical wastewater,a dominant strain was selected by bioenhanced treatment based on 2 α-phenylethylamine degrading bacteria P1 and P2 in fosfomycin pharmaceutical wastewater from previous work,and the optimal growth conditions were studied. The results showed that the dominant degrading one was P2 among P1 and P2. The optimal growth conditions were as follows:inoculation volume 20%,温度35℃,pH 7. The degradation efficiency of P2 was affected by the number of passage. After 17 generations,P2 began to degrade slowly. The degradation efficiency of α-phenylethylamine was 76% when the α-phenylethylamine dominant bacterium was put into the actual fosfomycin pharmaceutical wastewater.

Key words: fosfomycin, pharmaceutical wastewater, α-phenethylamine, dominant bacteria, growth condition
