The invention discloses an antibacterial natural latex product based on a quaternary ammonium salt antibacterial agent and a preparation technology of the antibacterial natural latex product, and belongs to the technical field of latex materials. The antibacterial natural latex product is prepared from the following components by weight: 90 to 100 parts of natural latex, 1 to 9 parts of sulfur, 1 to 5 parts of a vulcanization accelerator, 1.5 to 2 parts of an anti-aging agent, 1 to 6 parts of zinc oxide, 0.5 to 2 parts of sodium fluosilicate, 1 to 3 parts of potassium castorate, 0.1 to 2 parts of potassium oleate, 0.5 to 1 part of potassium permanganate and 0.1 to 3 parts of the quaternary ammonium salt antibacterial agent. The antibacterial natural latex product is based on the antibacterial characteristic of a low-concentration quaternary ammonium salt compound. The adopted quaternary ammonium salt compound has the advantage of stable performance, and the compound is tightly combined with latex polymer molecules and cannot permeate the skin of people or an animal by changing the physicochemical property of material surface. The latex product prepared in the invention has the advantages of high antibacterial property, hygiene, high practicability and the like, and has a broad market prospect.

The invention discloses two strains of functional microorganisms, Bacillus pierreae, respectively, the preservation numbers are GDMCC NO: 61542, GDMCC NO: 61541, and the names are Paenibacillus peoriae GXMD-hs-28 or Paenibacillus peoriae GXMD-hs-35. The strain is simple to screen and easy to cultivate, and the inventor has also established a corresponding cultivation method. Studies have shown that the fermentation broth of GXMD‑hs‑28 or GXMD‑hs‑35 has a good control effect on citrus canker. The effect is comparable. The discovery of this strain enriches the available microbial resources in my country, and has the advantages of stable bacteriostatic effect, high efficiency and environmental friendliness, and has a good application prospect in the prevention and treatment of citrus canker.

The invention discloses an antibacterial printing paste composition, a method for preparing glazed tiles using the same, and glazed tiles. A kind of bacteriostatic printing paste composition, comprises bacteriostatic agent, also comprises bacteriostatic material bonding dispersant and bacteriostatic material protective agent; Calculated by weight percentage, the raw material component of described bacteriostatic material bonding dispersing agent comprises 5 ~20% carbo resin, 5~15% saponite soil, 20~55% silicon boron frit powder, 15~30% alumina and 5~15% opal; calculated according to weight percentage, the antibacterial material protective agent The raw material components include 20-30% zirconia, 10-20% tin oxide, 3-10% yttrium oxide, 5-15% opal, 10-25% lithium carbonate and 5-15% rutile. The prepared glazed tile has good antibacterial performance, good antibacterial durability and long antibacterial time, which solves the problem of poor antibacterial effect and durability when the traditional antibacterial agent is directly mixed into raw glaze.

Derivative polypeptide derived from a grass carp interferon and an application of the derivative polypeptide. An amino acid sequence of the derivative polypeptide is as shown in SEQ ID NO:1; the interferon-derived polypeptide has a high-efficiency antibacterial effect and can take effect against drug-resistant Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Streptococcus agalactiae, Vibrio fluvialis or Aeromonas hydrophila. The interferon-derived polypeptide is less toxic to eukaryotes and can effectively reduce the mortality of mice in a mouse disease model caused by pathological bacteria. The interferon-derived polypeptide which is small in molecular weight is easily synthesized and has a good application value.
