Abstract

The invention discloses pediococcus acidilactici P3-4 which is preserved in a common microorganism center of the Chinese microorganism culture preservation management council. The preservation serial number of the pediococcus acidilactici P3-4 is CGMCC No.10574. A novel method for screening lactic acid bacteria is established based on the combination of the microorganism method and the chemical method, a culture medium is selected through antibiotics for primary screening and secondary screening, and a lactic acid bacterium which can degrade erythromycin and roxithromycin is screened out from soil. A reasonable and effective method for screening a strain for degrading erythromycin and roxithromycin is established, the proper required lactic acid bacterium strain is obtained, primary screening and secondary screening of the lactic acid bacterium for degrading erythromycin and roxithromycin are achieved through separation, purification and screening of lactic acid bacteria, and the safe and effective strain for degrading erythromycin and roxithromycin is obtained through screening. The pediococcus acidilactici P3-4 is used for treatment of pollution of erythromycin and roxithromycin and has the advantages that secondary pollution is avoided, treatment efficiency is high, the application range is wide, and cost is low. More options are provided for treating antibiotic pollution in complicated environments through microorganisms.

Description

technical field [0001] The invention relates to a strain of microorganism, screening identification and application, in particular to a strain of Pediococcus lactis P3-4 and its screening identification and application in degrading erythromycin and roxithromycin, belonging to the technical field of detection and application of microorganisms. Background technique [0002] Lactic acid bacteria are mainly distributed in a slightly acidic environment rich in mineral and organic nutrients. Dairy products, meat products, kimchi, fruit wine, vegetables and other materials are rich in lactic acid bacteria. In addition, animal digestive tracts are also important sources of lactic acid bacteria. Lactic acid bacteria play an important role in the nutrition and health of animals. They have the effects of antibacterial and anti-inflammatory, anti-oxidation, anti-tumor, lowering cholesterol, and improving immunity. [0003] Macrolide antibiotics have outstanding antibacterial activity ag...
