System for detecting content of cyanobacteria toxin in marine products

Abstract

The invention belongs to the technical field of cyanobacteria toxin content detection, and discloses a system for detecting content of cyanobacteria toxin in marine products. The system for detectingthe content of cyanobacteria toxin in marine products comprises a volume acquisition module, a power acquisition module, a weight acquisition module, a central control module, a crushing module, a soaking module, an extraction module, a DNA concentration detection module, a toxin yield determination module, a calculation module and a display module. The protein is extracted from marine product cyanobacteria through the DNA concentration detection module, the obtained protein has good thermal stability and acid-base tolerance, then the DNA concentration of the protein in an extracting solutionis detected under the wavelength of 260 nm through a NanoDropND-100 spectrophotometer, the detection accuracy is greatly improved, and detection is simple; meanwhile, the accuracy of measuring the yield of the cyanobacteria toxin is greatly improved through the toxin yield measuring module.

Description

technical field [0001] The invention belongs to the technical field of cyanobacteria toxin content detection, in particular to a detection system for cyanobacteria toxin content in seafood. Background technique [0002] Cyanobacteria, formerly known as blue algae or blue-green algae, are a class of long evolutionary history, negative Gram stain, no flagella, chlorophyll a, but no chloroplast (different from eukaryotic living algae), large single-celled prokaryotes capable of aerobic photosynthesis. The difference from photosynthetic bacteria is that photosynthetic bacteria (Rhodospirillum) carry out relatively primitive photosynthetic phosphorylation, do not release oxygen during the reaction process, and are anaerobic organisms, while cyanobacteria can perform photosynthesis and release oxygen. Its development makes the entire earth's atmosphere develop from anaerobic state to aerobic state, thus giving birth to the evolution and development of all aerobic organisms. So f...

Problems solved by technology

[0003] In summary, the existing problems in the prior art are: the existing detection system for cyanobacterial toxin content in seafood is complicated to detect the concentration of cyanobacterial DNA, and the error is large; at the same time, the detection of cyanobacterial toxin output is inaccurate
