Description

Technical Field

[0001] The utility model relates to the technical field of microbial research and teaching devices, and in particular to a self-luminous bacteria display and observation device. Background Art

[0002] Luminescent bacteria, mostly marine, are responsible for the bioluminescence of the ocean surface, along with bioluminescent plankton. Under normal physiological conditions, luminescent bacteria emit visible fluorescence with a wavelength between 450 and 490 nm, visible to the naked eye in darkness. While luminescent bacteria vary in morphology, their physiological characteristics are remarkably similar. They generally do not liquefy gelatin and do not produce toxic substances when breaking down proteins. They often parasitize various animals, causing "luminescence disease," or parasitic luminescence. These bacteria are typically transmitted to offspring via their host's eggs. Some bioluminescent fish and squid live in symbiosis with luminescent bacteria, utilizing their bioluminescence. These bacteria generally prefer low temperatures, with an optimum temperature of approximately 18°C, and do not emit light above 37°C. Luminescence is an enzymatic oxidation reaction that requires FM-NH2, a long-chain saturated aldehyde (O2), and luciferase. FMNH2 is generally considered to be luciferin. There are many kinds of luminous bacteria, reaching more than 100 species, typical ones include Achromobacter fisheri, Vibrio phosphoresce, Bacillus photogenus, etc.

[0003] The use of luminescent bacteria to create biosensors is a hot topic of research. The luminescence intensity of luminescent bacteria exhibits a good linear relationship with the concentration of certain pollutants, enabling them to stably, sensitively, and rapidly reflect changes in environmental pollutant concentrations. Therefore, the use of luminescent bacteria to create recognition elements has become a hot topic in sensor research and development both domestically and internationally. The expression of luminescent genes (luxgenes) contained in luminescent bacteria directly results in bioluminescence, which is highly intuitive and easy to detect. Consequently, these bacteria are widely used in genetic manipulation, serving as marker and reporter genes to study gene transduction, expression, and regulation.

[0004] Currently, the most studied luminescent bacteria include Photobacterium phosphoreum, which can reproduce in the carcasses and meat of cattle and horses; when it invades the human body, it produces luminescent urine. Photobacterium phosphoreum is also used in GB / T15441-1995, "Determination of Acute Toxicity of Water - Luminescent Bacteria Method."

[0005] Research institutions need specialized displays and observation devices for luminescent bacteria in their research, education, and science promotion. However, no such devices are currently available on the market. Utility Model Content
