ABSTRACT:
The growth of micro-organisms, including cells, molds, yeasts, bacteria and the like, under conditions of substantially zero gravity, is accomplished in a closed system maintained within a space vehicle in orbital flight including mechanisms for supplying oxygen of an optimum bubble size range and number density of bubbles, to a suitable culture medium, continuously dialyzing the culture medium of the micro-organism suspension against an excess of fresh culture medium to remove metabolites and replenish nutrients, supplying additional growth medium to the culture as needed, and recovering desired products of the fermentation, including, for example, enzymes, steroids and pharmaceuticals.
