This invention discloses a bifunctional engineered magnetotactic bacterium. The engineered magnetotactic bacterium is constructed using a recombinant PmamC-MamC-(Gly₄Ser)₃-MagLov fusion gene fragment to construct the expression plasmid pBBR1-MagLov-MamC. Using Magnetospirillum gryphiswaldense MSR-1 as a host, the recombinant expression plasmid pBBR1-MagLov-MamC is conjugated to obtain the bifunctional engineered magnetotactic bacterium MSR-1-MagLov capable of expressing the MagLov-MamC fusion protein. This invention also discloses the construction method and its applications. This invention overcomes the technical bias of exogenous proteins inhibiting magnetosome synthesis, achieving the integration of magnetotactic motility and magnetosensitive fluorescence.
