The invention belongs to the field of biotechnology, and particularly relates to bacillus amyloliquefaciens MY001 and application thereof. According to the technical scheme of the bacillus amyloliquefaciens MY001 and the application thereof, the bacillus amyloliquefaciens MY001 with the chitin degradation capability is screened and separated from soil in which asparagus is planted and is preservedin China General Microbiological Culture Collection Center on July 26th, 2017, the strain name is bacillus amyloliquefaciens MY001, and the preservation number is CGMCC NO.14460; the bacterial strainof the bacillus amyloliquefaciens MY001 can be used for inhibiting phomopasis asparagi germs; a specific application method for the bacillus amyloliquefaciens MY001 comprises the step of adding 1% ofcolloidal chitin into a bacillus amyloliquefaciens MY001 microbial inoculum with the concentration of 1*10<7> cfu / mL so as to form a complex microbial inoculant; and the complex microbial inoculum has great significance in preventing and treating phomopasis asparagi.

The invention provides an injection-use pharmaceutical composition comprising cefathiamidine and tazobactam sodium, and the pharmaceutical composition has a cooperatively antibacterial effect. The pharmaceutical composition comprises the following ingredients: by weight, 1-4 parts of the cefathiamidine, 1-2 parts of the tazobactam sodium, 2-6 parts of PLGA; 0.2-0.5 parts of L-arginine; 0.5-1 parts of PVP; 0.5-1 parts of mannitol; 0.5-1 parts of glycine; and 1-2 parts of tween. The pharmaceutical composition has the advantages of high stability, good redissolubility, simple preparation processes, a good inhibitory effect on staphylococcus aureus, staphylococcus epidermidis and staphylococcus epidermidis, and a definite curative effect, can reduce the dosage of a single prescription preparation and shorten the treatment period, and has broad market prospects.

The invention discloses an antibacterial implanted tooth root and a manufacturing method thereof. The implanted root comprises: an implant body, a connecting screw fixed in the implant body, an abutment fixed on the connecting screw and used for connecting a crown, formed on The antibacterial film on the surface of the implant, the elastic sealing film arranged between the implant and the abutment, the groove ring formed on the implant, the groove ring formed on the abutment and corresponding to the snap-in connection of the groove ring part, the sealing protrusion arranged on the abutment; the elastic sealing film forms an inner seal with the groove ring and the clamping part; the elastic sealing film forms an outer seal with the sealing protrusion and the edge of the implant; Realize inner seal and outer seal at the same time to achieve antibacterial, by adding antibacterial film on the surface of the implant, to achieve antibacterial and at the same time increase the proliferation and adhesion of cell tissue, speed up the recovery speed and effect of implant teeth, and prolong the Lifespan of dental implants.

The invention discloses a non-post-processing bacteriostatic blend. The blend is formed by three groups of fibers. The first group of fibers is fibers having an antibacterial property without bacteriostatic processing. The second group of fibers is fibers with softness and high moisture regain, and rigidity resistance is lower than 80cN and convention moisture regain is greater than 8%. The thirdgroup of fibers is chlorofibre fibers and / or modacrylic fibers with chloride, wherein cross-sectional flatness is greater than 1.08 and the convention moisture regain is less than 2.5%. The three groups of fibers comprise, by weight, 3% to 26% of the first group of fibers, 18% to 48% of the second group of fibers and 26% to 79% of the third group of fibers. In the invention, the fibers with the high moisture regain are adopted to absorb moisture as quickly as possible and transmit the moisture to the reverse side of the blend; the hydrophobic fiber with a special mechanism can transmit the water to the longitudinal direction of the fiber, the evaporation area of moisture is expanded, and the blend is dried as soon as possible to form the microscopic environment of moisture absorption and sweat releasing or moisture absorption and warm keeping; and a moist micro-environment required for bacterial reproduction is reduced so that a bacteriostatic fiber can achieve a bacteriostatic effect.

The invention provides a compound ceftiofur sodium injection with significant antibacterial action. The compound ceftiofur sodium injection comprises the following components in parts by weight: 1-4 parts of ceftiofur sodium, 1-2 parts of magnolol, 0.5-1 part of sodium sulfite, 0.5-1 part of glycine and 1-2 parts of Tween. The injection disclosed by the invention is high in stability and simple in preparation process, has a good inhibiting effect on swine escherichia coli, has an accurate curative effect on porcine colibacillosis, is capable of reducing the dosage of a prescribed preparation and shortening the treatment cycle, and has a wide market prospect.

The invention discloses a zinc phthalocyanine-chitosan oligosaccharide conjugate as well as a preparation method and application thereof. The zinc phthalocyanine-chitosan oligosaccharide conjugate refers to a conjugate of terminal carboxyl mono-substituted zinc phthalocyanine and chitosan oligosaccharide or quaternary ammonium derivatives thereof. The zinc phthalocyanine-chitosan oligosaccharide conjugate can be applied to photodynamic antibiosis, photodynamic cancer resistance, photodynamic diagnosis and photodynamic disinfection. The zinc phthalocyanine-chitosan oligosaccharide conjugate disclosed by the invention has zinc phthalocyanine and chitosan oligosaccharide or chitosan oligosaccharide ammonium salt double functional groups, and the synergy therapy effect can be achieved during photodynamic antibiosis; meanwhile, the chitosan oligosaccharide has excellent water solubility and biocompatibility, and can achieve the effects of effectively improving the amphiphilic property and biocompatibility of the zinc phthalocyanine, reducing the toxicity and improving the clinical application value of the zinc phthalocyanine.
