The application discloses a mussel polysaccharide and a preparation method and application thereof. The mussel polysaccharide MP-I with a novel structure is prepared from Mytilus coruscus through the process steps of water extraction and concentration, enzymatic deproteinization, alcohol precipitation and anion exchange, and the like. Animal experiments prove that the mussel polysaccharide MP-I prepared by the application can effectively improve intestinal flora and relieve intestinal inflammation by inhibiting the expression of inflammatory signal pathways such as JAK2 / STAT3 and NF-kappa B. Therefore, the mussel polysaccharide MP-I is a natural and safe drug or food for improving inflammatory bowel disease, can effectively improve the inflammatory bowel disease, is safe, non-toxic and free of side effects, the raw material is abundant, the steps are simple, the cost is low, and the effect is remarkable.

This invention relates to the field of molecular biology, and in particular to a molecular marker, primer pair, and their applications related to mussel species. The invention provides a molecular marker related to mussel species, comprising molecular marker 1 with the nucleotide sequence shown in SEQ ID NO.1 and molecular marker 2 with the nucleotide sequence shown in SEQ ID NO.2, and designs an amplification primer pair based on molecular marker 1 and molecular marker 2. Results from specific embodiments of the invention show that this primer pair can accurately identify *Mussela purpurea*, *Mussela thick-shelled*, and hybrid mussels. Therefore, the molecular marker and primer pair provided by this invention can be used to identify and screen *Mussela purpurea*, *Mussela thick-shelled*, or hybrid mussels of *Mussela purpurea* and *Mussela thick-shelled*, promoting the orderly development of artificial breeding and aquaculture production of mussels.

The invention relates to the technical field of biology, in particular to mytilus coruscus exosome-like nano-vesicles and application thereof in preparation of osteogenesis products. The functional activity research system of the exosome-like nano vesicles from aquatic products can be improved in the academic level, meanwhile, novel safe and efficient active substances are explored for the bone health field, high-value utilization of shellfish resources can be promoted, the academic value is remarkable, and the method has important industrial application prospects.

The invention relates to the technical field of molecular biology, in particular to a C-type lectin gene MytiCTL17A and application of coding protein of the C-type lectin gene MytiCTL17A. The invention discovers and verifies that the C-type lectin protein MytiCTL17A from mytilus coruscus has calcium ion dependence, remarkable and broad-spectrum microalgae agglutination activity for the first time. Experiments prove that the protein can effectively agglutinate multiple different microalgae (including chlorella and two kinds of isochrysis) in taxonomy, and an obvious agglutination block mass is formed in a short time. Compared with lectin reported in early literatures, the protein provided by the invention shows excellent broad spectrum, which means that a single preparation can cope with various microalgae problems, and has wider application potential. The protein provides a brand new core material basis for developing a new generation of efficient, environment-friendly and broad-spectrum microalgae treating agent.
