Experimental apparatus for soil bacteria isolation and enumeration

Abstract

The invention relates to the field of bacterial experimental equipment, in particular to an experimental apparatus for soil bacteria isolation and enumeration, comprising an apparatus body, a stock solution preparation unit, a diluting unit, a conveying unit, a coating unit, a marking unit, a sterilizing unit, a drying unit, a water supply unit and a control unit; the stock solution preparation unit is used for preparing a solution of bacteria in soil, the diluting unit is used for diluting stock solution in gradient manner, the conveying unit is used for conveying a culture dish, the coating unit is used for coating a culture medium, the marking unit is used for marking the culture dish, the drying unit is used for keeping the inside of the apparatus body dry, and the water supply unit is used for supplying aseptic distilled water. The traditional manual isolation and enumeration method for soil bacteria is replaced, the experimental cycle is shortened, labor intensity of experimenters is reduced, and disturbances on experimental results due to the differences of operating skills of experimenters are avoided; in addition, the apparatus has no need for use with an ultra-clean workbench, and experimental equipment resources are saved.

Description

technical field [0001] The invention relates to the field of bacteria experiment equipment, in particular to an experiment device for separating and counting soil bacteria. Background technique [0002] Soil is the base camp of bacteria life, and it is the main source of bacteria to find and discover bacteria with important application potential. To obtain pure bacteria, it is necessary to separate bacteria from soil. In the process of isolating bacteria, it is necessary to dissolve the soil sample to form a stock solution, then dilute the stock solution to form dilutions of different concentrations, and then the experimenter moves the dilution to the prepared medium and spreads it. The above operation process All are done manually by the experimenter. During the operation, the experimenter needs to concentrate to obtain the ideal experimental results, which requires a high level of operation of the experimenter; and it takes a lot of time for the experimenter to separate an...

Problems solved by technology

In the process of isolating bacteria, it is necessary to dissolve the soil sample to form a stock solution, then dilute the stock solution to form dilutions of different concentrations, and then the experimenter moves the dilution to the prepared medium and spreads it. The above operation process All are done manually by the experimenter. During the operation, the experimenter needs to concentrate in order to obtain the ideal experimental results, which requires a high level of operation of the experimenter; and it takes a lot of time for the experimenter to separate and coat a bacterium. Especially when bacteria are separated from a large number of different soil samples, the labor intensity of the experimenter will be increased, which is not conducive to the progress of the experiment.
