Description

Technical Field

[0001] The utility model relates to the field of soil bacteria experiments, in particular to a device for graded dilution of soil bacteria. Background Art

[0002] Soil bacteria are tiny single-cell prokaryotes that live in the soil. Soil bacteria are the most numerous and widely distributed among soil microorganisms, including autotrophic bacteria and heterotrophic bacteria. Autotrophic bacteria can directly utilize light energy or the energy released by the oxidation of inorganic substances, and can assimilate carbon dioxide for nutrition, such as nitrifying bacteria and sulfur bacteria. Heterotrophic bacteria obtain energy and carbon sources from organic matter. Existing soil bacteria are usually sampled and diluted in simple test tubes during experiments. Due to excessive mixing of soil bacteria, the impurities are too mixed, making it difficult to perform experimental operations and reducing the overall use effect. Therefore, we propose a device for graded dilution of soil bacteria to solve the above problems. Utility Model Content
