Abstract: The present invention relates to an apparatus for real-time continuous measurement of airborne microorganisms including a body unit, a vaporization unit, a liquefaction unit, a coating unit, and a measurement unit. The body unit has an inlet through which airborne microorganisms are introduced and an outlet through which airborne microorganisms are discharged. The vaporization unit vaporizes a lysis solution and supplies the vaporized lysis solution to the inside of the body unit. The liquefaction unit cools the vaporized lysis solution to condense the vaporized lysis solution on the surfaces of the airborne microorganisms. The coating unit applies a light-emitting agent onto the airborne microorganisms lysed by the lysis solution. The measurement unit detects the intensity of light generated by reacting the airborne microorganisms and the light-emitting agent and measures the concentration of the airborne microorganisms.
