A cell culture method proliferates microorganisms, particularly fungi such as molds, actinomycetes, animal cells, plant cells and so on to produce useful substances such as antibiotics, enzymes, proteins, polysaccharides, physiological active substances, and animal and plant hormones. Porous material including medium and cells to be proliferated is moved, whereby air is supplied to the surface of the porous material.
