Embodiment 1

[0080] Example 1, such as figure 1 with 2 Shown:

[0081] A cylinder for cultivating microorganisms, comprising a cylinder 1 with a closed lower end and an open upper end and a cover 2 matched with the open end of the upper end of the cylinder 1, and the inner space of the cylinder 1 is divided from bottom to top into Culture substrate chamber 3 and gas chamber 4, described culture substrate chamber 3 is used for containing the culture medium suitable for microbial growth, and described gas chamber 4 is used for containing the suitable gas suitable for microbial growth, also is provided with in described barrel 1 A gas replacement device, the gas replacement device is used to replace the gas in the gas chamber 4 with a new suitable gas.

[0082] In the scheme of this application, the culture medium suitable for microorganism cultivation is the current conventional culture medium, which can be a liquid medium, or a solid medium or a colloidal medium. For different types of mi...

Embodiment 2

[0084] Example 2, such as figure 1 with 2 Shown by:

[0085] A gas replacement device for the culture cylinder of the above embodiment, the gas replacement device includes a replacement component and a gas discharge component, the gas discharge component is used to communicate the gas chamber 4 with the external space of the cylinder body 1, the The replacement component is used to push the gas in the gas cavity 4, so that the gas in the gas cavity 4 is discharged out of the barrel 1 by the gas discharge component. In the gas replacement device of this embodiment, the replacement component and the gas discharge component are separated to prevent the incoming gas from being polluted by the discharge residue.

[0086] As a preferred embodiment, the gas exhaust assembly includes a communication pipe 5, one end of which communicates with the gas chamber 4, and the other end communicates with the external space of the cylinder 1 through the cylinder 1 .

[0087] As a preferred ...

Embodiment 3

[0105] Example 3, such as figure 1 with 2 Shown by:

[0106] A microbial culture system, including the above-mentioned microbial culture tube, also includes a temperature control cabin 15, the temperature control cabin 15 has a temperature control chamber 16 capable of maintaining a stable temperature in the cavity, all or the lower part of the culture tube As for the inside of the temperature control chamber 16 . In microbial culture, the temperature of the medium and the surrounding environment of the microorganism is also one of the important factors. Whether the temperature is suitable determines the quality of the growth and development of the microorganism. In actual microbial cultivation, some microorganisms will absorb heat, resulting in the temperature of the culture substrate Some microorganisms will release heat, leading to an increase in the temperature of the culture substrate. These changes in temperature often inhibit the further growth and development of micr...

Abstract

The invention relates to the technical field of microbial culture, and in particular to a gas replacing device for a microbial culture cylinder, and the culture cylinder. The gas replacing device comprises a replacing component and a gas discharging component, wherein the gas discharging component is used for making communication between a gas cavity of the culture cylinder and an external space of a cylinder body of the culture cylinder; the replacing component is used for pushing gas in the gas cavity to discharge the gas in the gas cavity out of the cylinder body through the gas dischargingcomponent; the gas discharging component comprises a communicating pipe; one end of the communicating pipe communicates with the gas cavity; the other end of the communicating pipe passes through thecylinder body and communicates with the external space of the cylinder body; the communicating pipe is also provided with a one-way conducting device; and the one-way conducting device is arranged atone end, close to the gas cavity, of the communicating pipe. According to the gas replacing device disclosed by the invention, the replacing component and the gas exhaust component are separated, sothat inlet gas is prevented from being polluted by exhaust remains.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a gas replacement device and a cultivation cylinder for microorganism cultivation and cultivation cylinders. Background technique [0002] For microorganisms, it is a large group of organisms including bacteria, viruses, fungi, and some small protozoa, which widely exist in the biological world. Although the microorganisms are small, they are closely related to human life. It is widely involved in many fields such as medicine and health, industry and agriculture, and environmental protection. [0003] Over the years, microbiologists have carried out scientific experiments in various aspects such as classification, physiology, and genetics, studied the physiological and biochemical characteristics of microorganisms, and summed up a set of microbial detection, screening and cultivation methods, so that microorganisms can be cultivated according to people's needs. ...
