Its spores are open spiral to wavy, and its spores are oblong to cylindrical with a smooth surface. It exhibits distinct growth characteristics on different culture media and is facultatively thermophilic with specific carbon source utilization. It produces antibiotics such as cerulemycin, which inhibits Gram-positive bacteria and viruses, and aminosugar antibiotics, which inhibit Gram-positive and Gram-negative bacteria. The use of selective cultivation tools can help improve strain performance, such as selecting strains with high antibiotic production to increase antibiotic yield and quality, and optimizing their growth characteristics. It can also ensure strain stability, reduce variation and mutation during long-term cultivation, and maintain excellent traits and production capacity during multiple passages and large-scale cultivation.

[0003] The breeding and cultivation device generally includes an inoculation device, a cultivation device, a screening device and an environmental control device. The environmental control device is divided into an incubator, a shaker, a pH meter and an acid-base adjustment device.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1 、 Figure 2 and Figure 3The utility model provides an embodiment of a dark Streptomyces strain selection and cultivation tool, comprising an incubator 1. The incubator 1 serves as the main structure of the entire selection and cultivation tool, and provides a closed and controllable environmental space for the cultivation of dark Streptomyces strains. The interior of the incubator 1 is fixedly connected to a mounting frame 4, and a placement plate 3 is slidably connected to one side of the outer wall of the mounting frame 4. The mobility within the incubator 1 is achieved through the sliding connection with one side of the outer wall of the mounting frame 4. The mounting frame 4 is internally installed with an installation component for enabling the placement plate 3 to be clamped, fixed, and returned to its original position. The placement plate 3 is internally provided with a card slot 7. The placing plate 3 is internally installed with a connecting assembly for releasing the placing plate 3 from its limit position. The mounting assembly includes a fixing column 6, one end of which is fixedly connected to the inside of the mounting frame 4, and the other end is fixedly connected to the inside of the mounting frame 4, providing a fixed support shaft for components such as a spring 5 and a sliding plate 12. The fixing column 6 is sleeved with a spring 5, the main function of which is to provide elastic force. The spring 5 is fixedly connected to the inside of the mounting frame 4, and one end of the spring 5 is fixedly connected to the sliding plate 12. The sliding plate 12 can move in the direction limited by the fixing column 6 and the slide groove 8 under the elastic force of the spring 5 and the drive of the external force. The upper part slides smoothly, the sliding plate 12 is slidably connected to one side of the outer wall of the fixed column 6, and a slide groove 8 is opened inside the mounting frame 4. One side of the outer wall of the sliding plate 12 is slidably connected to the inside of the slide groove 8. A spring three 13 is fixedly connected to the sliding plate 12. The spring three 13 provides additional elastic force for the card block 14, so that the card block 14 can maintain a stable card connection state in the card slot 7. One end of the spring three 13 is fixedly connected to the card block 14. One side of the outer wall of the card block 14 is slidably connected to the inner wall of the card slot 7. Its shape and size match the card slot 7. It is a key component for realizing the card connection and fixation of the placement plate 3. Cooperating with each other, under the joint action of spring 1 5 and spring 3 13, the placement plate 3 is firmly fixed on the mounting frame 4. The connecting component includes a button 10, and one side of the outer wall of the button 10 is slidably connected to the inside of the placement plate 3. The upper surface of the button 10 is fixedly connected with an abutment column 11, and one side of the outer wall of the abutment column 11 is slidably connected to the inside of the card slot 7. When the button 10 is pressed, the abutment column 11 moves upward in the card slot 7 and squeezes the card block 14, so that it overcomes the elastic force of spring 3 13 and moves toward the inside of the sliding plate 12. The abutment column 11 is sleeved with spring 2 9, and one end of spring 2 9 is fixedly connected to the upper surface of the button 10.

[0026] Reference Figure 1 and Figure 4A control panel 20 is fixedly connected to one side of the outer wall of the incubator 1, and a supporting foot 2 is fixedly connected to the lower surface of the incubator 1, which lifts the incubator 1 a certain distance from the ground to prevent the incubator from directly contacting the ground and avoiding damage to the incubator due to moisture, unevenness or other factors on the ground. A sealing ring 19 is fixedly connected inside the incubator 1. The sealing ring 19 is used to strengthen the sealing. Its main function is to effectively prevent the gas exchange between the inside of the incubator 1 and the external environment, ensuring that the gas composition and concentration in the incubator remain stable. A chute 2 15 is provided inside the incubator 1, and one side of the outer wall of the placement plate 3 is slidably connected to the inner wall of the chute 2 15, providing a precise guide track for the sliding of the placement plate 3, and the rotation connection inside the incubator 1 There is a glass door 18, and one side of the outer wall of the glass door 18 is in contact with one side of the outer wall of the sealing ring 19, which not only ensures the sealing of the incubator 1, but also provides a visual window, which is convenient for the experimenter to observe the growth status of the dark Streptomyces species in the incubator at any time. The incubator 1 is rotatably connected to the door 16, and the outer wall of the door 16 is fixedly connected to the sealing gasket 17. The outer wall of the sealing gasket 17 is in contact with one side of the outer wall of the incubator 1. When the door 16 is closed, the sealing gasket 17 generates sufficient pressure between the door 16 and the incubator 1 to fill the tiny gap between the two, effectively preventing outside air, moisture and microorganisms from entering the incubator 1, and at the same time preventing the gas, heat and moisture in the incubator from leaking out.

[0027] Working principle: When the device is not in use, the spring 15 in the mounting assembly is in a compressed state. Under the action of the spring 15, the sliding plate 12 partially engages the card block 14 in the card slot 7 of the placement plate 3 to achieve the initial fixation of the placement plate 3. When the placement plate 3 needs to be moved, the button 10 on the placement plate 3 is pressed, which drives the abutment column 11 to move in the card slot 7 and pushes the card block 14 upward to separate from the placement plate 3. At this time, the placement plate 3 is unlocked, and then the placement plate 3 is pulled to slide outward along the slide groove 15 inside the incubator 1. The tension of the spring 5 makes the withdrawal action smooth. The incubator 1 is sealed mainly by the sealing gasket 17, the glass door 18 and the sealing ring 19. When the door 16 is closed, the sealing gasket 17 on the outside of the door 16 fits tightly against the outer wall of the incubator 1, forming the first sealing line of defense, effectively preventing outside air and microorganisms from entering the interior of the incubator 1. The glass door 18 is installed inside the incubator 1, and its outer wall fits against the outer wall of the sealing ring 19, further enhancing the sealing of the interior of the incubator 1, reducing heat exchange, and ensuring the stability of the culture environment. Finally, the double-layer placement plate 3 is provided to further improve the efficiency of using the device.
