FIELD: biochemistry.
SUBSTANCE: invention relates to biochemistry. Bioreactor for biochemical processes is disclosed. Bioreactor includes cylindrical vessel with device for medium mixing. Device for medium mixing consists of impeller, round partition and position control mechanism of impeller in height relative to surface of mixing medium. Impeller is horizontally fixed on vertical rod in upper part of vessel. Control mechanism includes rod vertically installed along vessel axis, connected by means of retainer with round partition for its rotation. Round partition is made with side diffuser holes at angle of 30–45° to circle and with top holes at angle of 45–60° to horizontal. Wherein above round partition additional impeller is placed on rod.
EFFECT: invention provides simplified design and elimination of power consumption.
