A connection device for fermentation container and extracellular fermentation product research container

Abstract

The invention discloses a connecting device for a fermented container and an extracellular fermented product researching container. The fermented container is a flat bottom flask with an aeration device and a stirring device, wherein a connecting pipe is arranged at the bottom of the flat bottom flask; the extracellular fermented product researching container is a test tube with an aeration device, wherein a connecting pipe is arranged at the bottom of the test tube; the connecting device is composed of a freely detachable glass sleeve coaxially melted with a G1 sand chip, coaxially arranged regenerated cellulose membrane, an O-shaped silica gel gasket and an inserting pipe inserted into the glass sleeve; the cross section at the bottom end of the inserting pipe is closely contacted with the O-shaped silica gel gasket; the G1 sand chip, the regenerated cellulose membrane and the O-shaped silica gel gasket are closely contacted by squeezing the cross section of the bottom end of the inserting tube; extending pipes with screw or dull polish sorted with the flat bottom flask and the bottom of the test tube are arranged at two ends of the device. The device provided by the invention is simple and rapid in assembly, freely detachable, convenient to use and is widely applied in an extracellular active component system for connecting the fermentation and researching the fermentation generation.

Description

technical field

[0001] The invention relates to a connection device for a fermentation and product research system, in particular to a connection device for a fermentation container and an extracellular fermentation product research container. Background technique

[0002] The current method for researching fermentation systems with specific activity is to separate and purify the active components (proteins, polysaccharides or small molecular substances, etc.) produced by the fermentation from the fermented extracellular fluid. The disadvantage of this research method is that it ignores the role of microorganisms or cells in the fermentation system, and cannot continuously supply active substances, especially some active components are likely to lose activity during the separation process. Another way to study the fermentation system with specific activity is to directly study the active components in the system, but because the extracellular components of the fermentation s...
