Culture bottle for anaerobic bacteria fermentation

Abstract

The invention discloses a culture bottle for anaerobic bacteria fermentation, and relates to the technical field of culture equipment. An air inlet pipe is inserted into one side of a bottle cap; thelower end of an air inlet pipe is suspended in the culture bottle; the upper end of the air inlet pipe penetrates through the bottle cap; the bottle cap is suspended on the upper side of the bottle cap; a first one-way valve is arranged at the upper end of the air inlet pipe; the first one-way valve is suspended above the bottle cap; an air outlet pipe is arranged on the other side of the bottle cap; the air outlet pipe is arranged in an L shape; a detection pipe is inserted into the upper side of the outer ring wall of the transverse pipe in the air outlet pipe; a sealing gasket is embedded in the detection pipe; a second one-way valve is arranged at the upper end of a vertical pipe in the air outlet pipe; the second one-way valve is suspended above the bottle cap; the lower end of the vertical pipe in the air outlet pipe penetrates through the bottle cap and then is suspended in a culture bottle; and the culture bottle is arranged in a heat preservation box in the heating mechanism.In the culture stage, a required gas environment can be provided according to the operation stage, and the device is small in size, small in occupied space and low in cost and has the advantages of reasonable arrangement, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to the technical field of culture equipment, in particular to a culture bottle for anaerobic fermentation. Background technique [0002] Anaerobic bacteria are a type of bacteria that grow better under anaerobic conditions than in aerobic environments, but cannot grow on the surface of solid medium in air and 10% carbon dioxide concentration. These bacteria lack a complete metabolic enzyme system , its energy metabolism is carried out in the form of anaerobic fermentation. The cultivation equipment of anaerobic bacteria includes anaerobic bags, anaerobic tanks and anaerobic workstations. However, anaerobic bags and anaerobic tanks can only provide corresponding The gas environment cannot provide the gas environment in the operation stage, and the anaerobic workstation that can be operated and cultivated in the whole process has the defects of high purchase and use costs and excessive space occupation. Contents of the invention ...
