Field of the Invention The present invention relates to a culturing unit applied to continuous cultivation of a cell or microorganism in a liquid for research or industrial use. 2. Description of the Related Art Conventionally, there has been an apparatus for culturing cells continuously and for a long period of time. However, there is only one culture line, and a gas exchange line and a medium exchange line are two separate lines.
There is no unit that can control and operate each line independently. In the above-mentioned conventional culture unit, the culture line is only a medium exchange line, and the medium is always exchanged to also perform gas exchange. Therefore, a long period of culture requires a large amount of medium. [0003] Further, an operator must observe the growth state of cells and microorganisms every day to judge the state of culture and adjust the culture medium and culture operation. As described above, the conventional culturing unit relies on the operator, and the culturing operation is manually performed, so that there is a high risk of contamination by various germs and the like. SUMMARY OF THE INVENTION [0004] The present invention eliminates the burden on the operator as seen in the conventional culture unit, and also carries out the operation peculiar to the operator and the danger of contamination by various bacteria during the culture operation. It is an object of the present invention to provide a liquid culturing unit that has no performance. Further, the present invention provides a liquid culture unit capable of efficiently performing oxygen supply and carbon dioxide exchange performed in a medium circulation process with a simple structure and capable of performing long-term culture with a small amount of medium storage. Is an issue. [0005] In order to solve the above-mentioned problems in the liquid culture unit, the present invention provides a gas exchange line having a medium circulation pump and a gas permeable tube for circulating a medium in a culture vessel. A fresh medium supply line connected to the culture vessel, comprising a culture medium tank for storing the culture medium, a pump for supplying the culture medium in the tank, and an on-off valve, and a tank and an on-off valve for storing waste liquid. A sensor unit equipped with a temperature, pH, dissolved oxygen, and amino acid concentration sensor for monitoring the properties of the culture medium, and a signal from the sensor unit, and controlling the pump and valve to monitor the culture medium; metabolites of properties Chi coercive to a value determined because Ji pre, cells or microorganisms are discharged
If the growth environment becomes inappropriate due to
While extracting the old medium in the liquid extraction line,
Supply fresh medium to the culture vessel through the supply line
A configuration in which a control device for replacing the ground is provided is adopted. As described above, the structure of the present invention in which a gas exchange line having a gas permeable tube, a valve, and a pump attached to a culture vessel for culturing cells or microorganisms is used as a closed system is employed. Then, the culture solution is circulated in this system using a pump. This makes it possible to sufficiently supply cells or microorganisms with oxygen and the like necessary for growth without replacing the medium anew, so that the growth environment is not suitable due to metabolites discharged by cells or microorganisms. Until the state is reached, long-term unmanned culture is possible without consuming the medium. Then, when the growth environment becomes inappropriate due to metabolites discharged by cells or microorganisms, extract the old medium from the culture vessel with the waste liquid extraction line provided by the present invention.Supply a new medium to the culture vessel through the fresh medium supply line To allow the medium to be changed. In the liquid culture unit of the present invention , the temperature, pH, dissolved oxygen, amino acid,
A sensor unit equipped with an acid concentration sensor, and receiving the signal from the sensor unit and controlling the pump and valve to control the culture medium
Since the properties employs a configuration in which a control device to keep the value determined because Ji pre monitors the properties of the medium by the sensor unit, the determination of the medium circulation rate by incorporating the controller in the liquid culture unit, Judgment of medium exchange and judgment of subculture are performed. By this determination of the control unit, the properties of the culture medium in the culture vessel can be set to a predetermined value by controlling the on-off valves and pumps provided in the gas exchange line pump, fresh medium supply line, and waste liquid extraction line, respectively. Changing the medium circulation amount, changing the medium, and transferring cells or microorganisms can be performed automatically to keep the medium. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a liquid culture unit according to the present invention will be described in detail with reference to the illustrated embodiments. First, the configuration of the liquid culture unit according to the present invention will be described with reference to the system diagram of FIG.

A tank 5 for receiving a used medium extracted from the cell culture chamber 1;
Is a sensor unit for monitoring the properties of the culture medium, and 7 is a gas permeable tube connecting the cell culture chamber 1, the pump 2 and the sensor unit 6. The gas permeable tube 7 with the pump 2 and the sensor section 6 interposed therebetween constitutes a gas exchange line for the cell culture chamber 1. Reference numeral 8 denotes an opening / closing valve provided on a line for sending a fresh culture medium from the culture tank 4 to the cell culture chamber 1 by the pump 3. The opening / closing valve 8 includes the pump 3, the culture tank 4, and the opening / closing valve 8. A medium supply line is configured. Reference numeral 9 denotes an opening / closing valve provided in a line connecting the cell culture chamber 1 and the waste liquid tank 5,
The line extending from to the waste liquid tank 5 constitutes a waste liquid extraction line. The valves 8 and 9 of these lines are configured to be automatically opened and closed by a control device as described later. Reference numeral 10 denotes a control device for judging a signal from the sensor unit 6 and controlling start / stop of the pumps 2 and 3 and opening and closing of the valves 8 and 9. FIG. 1 is a schematic diagram showing the configuration of a liquid culture unit according to the present invention in an easy-to-understand manner. FIG. 2 shows a specific arrangement of components in one embodiment of the liquid culture unit according to the present invention. is there. 2, parts corresponding to the components shown in the system diagram of FIG. 1 are denoted by the same reference numerals as those shown in FIG. 1, and the description of the configuration is omitted. In the liquid culture unit shown in FIGS. 1 and 2, under a steady culture state, the medium in the cell culture chamber 1 is fed into the sensor unit 6 in the middle as shown by an arrow 12 in FIG.
Gas permeable tube 7 with medium and medium circulation pump 2
Circulated through the gas exchange line constituted by
Based on signals from sensors such as temperature, pH, dissolved oxygen, and amino acids attached to the sensor section 6, the control device 10 monitors the properties of the culture medium and determines the culture state. Further, the gas exchange is performed by the pump
And the flow rate is changed to control the dissolution of oxygen from the gas permeable tube 7 into the culture medium and the exchange of carbon dioxide gas, so that the culture state can be maintained well.
