Rapid and efficient screening method for microcystins degrading bacterium

The invention discloses a rapid and efficient screening method for a microcystins degrading bacterium. The method comprises the steps of carrying out primer pair design, PCR amplification and product detection; designing primer pairs as shown in SEQ ID NO:1 and SEQ ID NO:2; adopting a DNA of to-be-screened microcystins degrading bacterium as a template and carrying out PRC amplification by using the primer pair to obtain an amplified product; and detecting the amplified product and completing screening of the microcystins degrading bacterium according to the detection result. Through synthesizing a gene amplification result, it is observed that MCs can be degraded by a bacterial strain screened through the method, the abandoned bacterial strain has no MCs degrading capability, so that the MCs degrading bacterium can be quickly screened by using the PCR detection method. 本发明公开了种微囊藻毒素降解菌的快速高效筛选方法，包括引物对设计、PCR扩增以及产物检测；设计如SEQ ID NO：1以及SEQ ID NO：2所述的引物对；以待筛选微囊藻毒素降解菌的DNA为模板，利用引物对进行PCR扩增，得到扩增产物；检测扩增产物，根据检测结果完成微囊藻毒素降解
