Abstract
A vessel is adapted to accommodate a liquid phase containing a nutrient liquid and micro-organisms which are to be aerobically grown. A gaseous phase is admitted into the presence of the liquid phase, and the resulting mixture is advanced to a mixing chamber where it is uniformly mixed by a rotary element having a plurality of baffles extending across the path of the advancing mixture. Additional projections also extend across the path and define constrictions therein with the baffles so that the advancing mixture is thereupon dispersed prior to being expelled into the vessel. The rotary element also has a Venturi-shaped passage provided with a throat which is operative for generating a region of suction when the rotary element is rotated so that the rate of advance of the mixture is accelerated.
