Color block card target board for microbial experiment and application thereof

Abstract

The invention relates to microbial culture technologies and in particular provides a color block card target board for a microbial experiment and application thereof. n first circular marks and a plurality of second circular marks are arranged on the card target board; the diameter of each second circular mark is 1 / 2 of the diameter of each first circular mark; an identification tag is arranged between the first marker line of each first circular mark and the second marker line of each corresponding second circular mark; m equally divided straight lines are arranged on the card target board, and the card target board is equally divided into 2m parts; two m partitions symmetrical to each other are formed in the card target board; each m partition is divided into m identification blocks; identification areas on the identification blocks are formed by the first marker lines of the first circular marks, the second marker lines of the second circular marks corresponding to the first circular marks and the equally divided straight lines; the identification tags between the first marker lines of different first circular marks and the second marker lines of the corresponding second circular marks are different and are respectively arranged on non-coincided identification areas; and the identification tags on the two m partitions are symmetrically arranged. According to the color block card target board, an experimenter can be helped to perform culture dish area partition and fixed point operation.

Description

technical field [0001] The invention relates to the technical field of microbiology, in particular to a color block card plate used in microbial experiments to help experimenters divide and position petri dishes and an application thereof. Background technique [0002] Microbial experiments are a large category of experiments in biology. Experiments such as inoculation of strains, confrontation culture, Oxford cup culture, and bacterial drug susceptibility experiments all need to be carried out at specific positions on the petri dish. In the experiment of inoculating strains, the picked hyphae, single colony, dipped bacterial solution, etc. are generally inoculated in the center of the petri dish. In the confrontation culture experiment, several species of bacteria required for confrontation growth are usually inoculated in the center of the petri dish and several midpoints between the center and the edge of the petri dish to observe the mutual influence between the strains....

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problem that the positioning on the petri dish is difficult in the existing microbial experiment, which seriously affects the accuracy and repeatability of the experiment, the present invention provides a microbiological experiment that can accurately help experimenters to divide the area of ​​the petri dish and perform fixed-point operations.
