Abstract
The method uses a culture receptacle including a layer of growth medium (3), a first end surface of which gives onto a first chamber (27) and the second end surface of which gives onto a second chamber (28), and includes a step of causing a higher pressure in the first chamber (27) than in the second chamber (28), with a view to allowing the diffusion, in the layer of growth medium (3), of the water which the latter contains and optionally of a rehydrating solution (29) deposited on the first end surface of the layer of growth medium. The cartridge has a body (2) with, between a grid (7) which the layer of growth medium (3) coats and an annular wall (8), a solid annulus (9) having towards the inside an extra thickness part forming a ridge (10).
