Description

Technical Field

[0001] The invention relates to a gradient geochemical environment microorganism enrichment and separation system. Background Art

[0002] In recent years, microbial isolation and culture technology has occupied an important position in microbiological research. By improving the culture medium formula and culture conditions, researchers can cultivate more types of microorganisms. In addition, modern molecular biology techniques such as 16S rRNA gene sequencing have also been widely used in the identification and classification of microorganisms. Despite many advances, microbial isolation and culture still face great challenges, including the fact that many microorganisms are difficult to culture under laboratory conditions. It is estimated that less than 1% of microorganisms can grow on traditional culture media. Different microorganisms have different requirements for culture conditions, including temperature, pH value, oxygen concentration, etc., which makes it very complicated and time-consuming to find suitable culture conditions for specific microorganisms. Efficient isolation and culture technology usually requires expensive equipment and reagents, which is a technical and economic barrier. However, pure culture of microorganisms can ensure the singleness and purity of the research object, thereby improving the accuracy and repeatability of experimental results. Through pure culture, researchers can gain a deep understanding of the physiological characteristics, metabolic pathways and ecological effects of specific microorganisms, which is helpful for the development of new drugs and industrial applications. Therefore, there is an urgent need for an economical and efficient microbial culture device to isolate a large number of microorganisms with application value from the environment.

[0003] Existing traditional microbial culture techniques have many shortcomings, mainly including low success rate, single isolated microbial species, susceptibility to cross-contamination, and high resource consumption. These shortcomings are mainly due to the fact that traditional culture techniques rely on a single culture medium and specific environmental conditions, which makes it difficult to meet the diverse growth needs of different microorganisms. In traditional culture techniques, most microorganisms cannot grow on a single culture medium, resulting in only a few microorganisms that can adapt to these conditions being successfully isolated. This not only limits our understanding of microbial diversity, but also leaves many microorganisms with potential application value undiscovered and unused. In addition, traditional techniques are susceptible to contamination by other microorganisms during the separation and culture process, resulting in reduced accuracy and reliability of experimental results. At the same time, in order to find suitable culture conditions, researchers need to conduct a large number of experiments, which is not only time-consuming and labor-intensive, but also requires a large amount of reagents and equipment, increasing research costs.

[0004] Therefore, in order to address the shortcomings of traditional microbial cultivation technology, such as low success rate, single separated species, susceptibility to contamination and high resource consumption, a gradient geochemical environment microbial enrichment and separation system is provided. Summary of the invention

[0005] The purpose of the present invention is to overcome the existing defects and provide a gradient geochemical environment microorganism enrichment and separation system, thereby improving the enrichment and separation efficiency of microorganisms.

[0007] Preferably, the glass barrel is in a columnar form, and is used to carry environmental samples, culture fluid, and quartz sand or other fillers that are conducive to the survival and separation of microorganisms, thereby forming different geochemical gradient layers.

[0008] Preferably, different geochemical gradient layers include but are not limited to changes in pH value, oxygen concentration, and nutrient elements.

[0013] Preferably, the feeding port is used to fill the glass barrel with environmental samples and quartz sand or other fillers that are conducive to the survival and separation of microorganisms.

[0014] The beneficial effects of the present invention are: The present invention can better simulate the complex conditions in the natural environment through the diversified geochemical gradients formed in the glass barrel, so that more types of microorganisms can grow under suitable conditions, thereby improving the success rate of cultivation; The present invention can enrich and separate a large number of different types of microorganisms by sampling at different gradient layers, thus overcoming the problem of separating a single species in traditional culture technology; The sampling port design of the present invention allows multiple sampling during the enrichment process, which helps to timely detect and control cross contamination and ensure the accuracy and reliability of the experimental results; The invention has a simple design and diversified culture conditions.

[0021] The design module 7 is used to design corresponding solid or liquid culture medium according to the detected geochemical and nutrient element characteristics for further separation and purification.

[0022] In the embodiment, the glass barrel 1 is in a columnar form, which is used to carry environmental samples, culture medium, and quartz sand or other fillers that are conducive to the survival and separation of microorganisms, thereby forming different geochemical gradient layers. The different geochemical gradient layers include but are not limited to changes in pH value, oxygen concentration, and nutrients; it can better simulate the complex conditions in the natural environment, allowing more types of microorganisms to grow under suitable conditions, thereby improving the success rate of cultivation.

[0023] In the embodiment, the sampling port 2 is used to extract microbial samples from different geochemical gradient layers in the glass barrel 1; by sampling from different gradient layers, a large number of different types of microorganisms can be enriched and separated, overcoming the problem of separating a single species in traditional culture technology, and multiple sampling can be performed during the enrichment process, which helps to timely detect and control cross contamination and ensure the accuracy and reliability of experimental results. In addition, the device is simple in design and has diversified culture conditions.
