Abstract
The cartridge has a body (2) with a grid (7) and an annular wall (8) oriented transversely to this grid and surrounding it, and having a layer (3) of growth media and a flexible fluid-tight film (4) tensioned over an end surface of the annular wall (8) and delimiting an end surface of the layer of growth media (3). According to the method, the surface of the layer of growth media (3) delimited at the time of manufacture by the tensioned film (4) is struck with air jets in order to impact on this surface the microorganisms present in the air. The apparatus has a positioning support common to a sieve for forming the air jets and to the body (2) of the cartridge (1).
