PLANT FOR CONTINUOUS GROWING OF MICROORGANISMS Russian patent published in 1994 - IPC

FIELD: microbiological industry. SUBSTANCE: plant has fermenter bank 1 provided with level gages 6 and fermentation medium recirculation system which has collector 7 mounted parallel to the horizontal line, and piping 8 provided with valves 9 which connect collector 7 to all fermenters 1. Valves 9 are connected to level gages 6. The plant may be adapted for a one-step and for a two-step fermentation. If fermentation medium level, controlled by level gages 6, exceeds the predetermined value, valves 9 open to let the fermentation medium to run from fermenter 1 to collector 7. By a one- step fermentation, the culture fluid from collector 7 is supplied to the final product production stage. By a two- step fermentation, the fermentation medium is supplied from collector 7 to any of the available fermenters 1 to utilize more fully the activity of producing culture and the carbon source. EFFECT: increased efficiency of the process. 1 dwg
