APPARATUS TO GROW MICROORGANISMS Russian patent published in 2009 - IPC C12M1/02 C12M1/04 

FIELD: mechanics, microbiology.

SUBSTANCE: apparatus comprises a vessel to receive culture liquid till a certain level. The said vessel has branch pipes to feed liquid mineral culture medium, air and to discharge accumulated biomasses, and, at least, one additional vessel making an adsorber of gaseous substrate. The aforesaid vessels have flanged rings fitted along the vessel axis to divide the vessel part filled with liquid into upward and downward channels. Air feed bubblers are arranged in the vessel upward channels. The vessels lower parts communicate via a liquid duct so that the main vessel downward channel communicates with the additional vessel upward channel, while the additional vessel downward channel communicates with the main vessel upward channel. Note that the liquid duct accommodates a liquid circulation agitator arranged between the vessels. The additional vessel ring upper flange can represent a funnel directed inside the downward channel and symmetrical to the downward channel axis. A surge pipe can be mounted at the flange center to communicate the vessel above-liquid part with the downward channel inner side. Note that another funnel can be mounted below and coaxially with the aforesaid funnel and surge pipe.

EFFECT: producing protein masses of aerobic microorganisms in using gaseous substrate as nutrition.
