A knock-out plasmid PHY300dsrf is established; and the plasmid comprises sgRNA and cas9 genes of the specific targeted target gene, a homologous restoration arm, and replication initial points and tolerance screening markers of Escherichia coli and Bacillus subtilis. The sgRNA of the specific targeted srfA-C gene can guide the cas9 protein to cut double strands at the specific site of the srfA-C gene, and can be used for accurate homologous recombination on the genome under the guide of the homologous restoration arm, thereby introducing the XhoI enzyme digestion site at the rupture. |
