Description

Technical Field

[0001] The embodiments of this utility model belong to the technical field of four-zone marking on blood agar plates, and more specifically, relate to an auxiliary device for four-zone marking on blood agar plates. Background Technology

[0002] The four-zone streak plating method involves diluting mixed microorganisms or different cells from the same microbial population on a plate using an inoculation loop, resulting in numerous independently distributed single cells. These cells are then cultured and multiply to form single colonies, which are typically considered pure cultures of the microorganism to be isolated. The principle is to achieve separation by repeatedly diluting the microbial sample "from point to line" on the surface of a solid culture medium. However, streaking in blood agar plates and petri dishes is usually done manually, leading to variations in streak quality and requiring considerable skill and experience from the operators. Therefore, there is an urgent need to develop methods to improve the quality of four-zone streaking and increase work efficiency.

[0003] To address the aforementioned technical problems, Chinese utility model patent CN207727073U discloses a microbial culture dish, comprising a dish lid, a dish box, and a four-zone line drawing indicator film. The dish box and dish lid are fixed together to form a hollow culture area, and the four-zone line drawing indicator film is affixed to the outer bottom of the dish box. This microbial culture dish has a simple structure. Utilizing the four clearly marked areas and line paths on the four-zone line drawing indicator film, inexperienced experimenters can independently complete experiments by referring to the indicator, improving the success rate and avoiding repeated experiments that waste valuable time and materials. Furthermore, the four-zone line drawing indicator film can be applied to blank culture dishes at any time, can be reused multiple times, and can be easily removed after use without interfering with the experimenter's observation of microbial morphology and distribution.

[0004] The above-mentioned patented technology improves the quality of drawing lines by adding drawing indicator diagrams in petri dishes or blood plates, but there are still the following technical problems or directions for improvement: (1) The above method is based on manual operation. In the case of dealing with a large number of four-zone drawing tasks, the method is difficult to improve work efficiency; (2) In response to the technical problems mentioned in (1), an auxiliary device should be proposed to replace manual drawing and mechanically automate the four-zone drawing function, so as to ensure work efficiency and achieve high quality and consistency of four-zone drawing.
