The wine body is coordinated in flavor, heavy in fragrant, enough in dryness, rounded and smooth. Differences in flavor, taste and color of the wine body caused by different components, brewing time and oak processing processes are avoided. The quality stability and flavor consistency of the finished wine are improved.

The invention discloses a fused antibacterial peptide, and a preparation method and an application thereof. Cecropin B (CB) and tachyplesin I (TP I) are serially connected to construct a fused antibacterial peptide CB-TP I, and the DNA sequence of the fused antibacterial peptide CB-TP I is synthesized through optimizing CB gene and TP I gene and is inserted to a fungal specific double T-DNA safe expression vector; and a fungus is transferred to produce a transgenic mycelium of the fused antibacterial peptide, and the extracted fused antibacterial peptide has the characteristics of greatly improved antibacterial ability, low dosage and no drug resistance. The produced fused antibacterial peptide mycelium is dried at a low temperature to directly prepare a feed additive, so the protein separation and purification process is omitted, the quality difference among all batches is small, the output is large, and the cost is low. The fused antibacterial peptide can increases the disease of livestock and poultry and reduce the use of antibiotics, and has wide social and economic benefits.

The invention relates to a method for suspension culture of Newcastle disease virus (NDV) by using a full-suspension passage cell line. The method comprises the following steps: inoculating the full-suspension EB66 cell line having a growth density of 8*10<6> cells/mL to 16*10<6> cells/mL with the NDV by using a two-stage culture method, continuously culturing after the virus is inoculated, and sampling every 12 hours so as to determine the EID50 of the virus; harvesting the virus when the titer of the virus is maximum, and storing the harvested virus so as to complete the culture of the NDV.The method adopts the duck embryonic stem cell EB66 passage cell line to culture the chicken NDV, thus effectively improving the titer and purity of the obtained virus, further enabling produced vaccines to have higher quality, and lowering the production cost.
