Abstract

The invention discloses a diethylstilbestrol degradation strain and an application thereof in sewage and animal manure treatment. Serratieae (Serratia sp.) S is preserved at China General Microbiological Culture Collection Center on August 26, 2014, wherein the strain preservation number is CGMCC 1.12941. The invention also discloses an application of the serratieae S and a fungicide of the serratieae S in degradation of estrogen, especially degradation of diethylstilbestrol. The serratieae S is obtained in a screening manner, the degradation rate on DES (diethylstilbestrol) of which the initial concentration is 50mg L<-1> can reach over 80% after an immobilized bacteria agent which is prepared from the strain is subjected to shake-flask culture in a laboratory for 7d, the immobilized bacteria agent is directly applied to DES-polluted water and animal manure, and the DES residue within a short period of time is reduced by over 90%, so that the problem of hazards of diethylstilbestrol DES to the water environment, animal manure and human health is solved.

Description

technical field

[0001] The invention belongs to the field of bioremediation of environmental pollution, and relates to a diethylstilbestrol-degrading bacterial strain and its application in the treatment of sewage and livestock manure. Background technique

[0002] Environmental estrogen has become the third largest environmental problem after the destruction of the ozone layer and global warming, and has been hailed as a time bomb that threatens the survival of human beings. In recent years, various levels of estrogen pollution have been found in many water bodies around the world, which have had adverse effects on humans and animals. In my country's Yangtze River, the Yellow River Basin also has the detection of estrogen. When the concentration of estrogen in water is 1ng·L -1 Sometimes it will interfere with the endocrine system of fish, resulting in the feminization of male fish. The normal physiological secretion and excretion of humans and animals will release estro...
