Luminescent bacterium kit

The utility model provides a photobacterium kit. The photobacterium kit comprises a plurality of reagent strips and a limiting assembly, a plurality of reagent grooves are formed in the reagent strip, a transverse limiting block is arranged on one side of the reagent strip, and a transverse limiting groove is formed in the other side of the reagent strip; a sliding groove is formed in one side of the reagent strip, and a vertical limiting groove is formed in the other side of the reagent strip; the limiting assemblies and the reagent strips are in one-to-one correspondence and are arranged in the sliding grooves in a sliding manner; when one reagent strip is vertically inserted into the transverse limiting groove of the other reagent strip through the transverse limiting block, the limiting assembly can be inserted into the vertical limiting groove, the transverse limiting block can limit the two reagent strips to be separated towards the two sides, and the limiting assembly can limit the two reagent strips t
