The invention discloses a Gluconobacter oxydans gene engineering bacteria for producing 2-KLG and its application. According to the invention, by means of a genetic engineering technology, sorbose dehydrogenase (SDH) and sorbosone dehydrogenase (SNDH) genes derived from Ketogulonigenium vulgare are connected by a connecting peptide and then expressed in Gluconobacter oxydans so as to obtain G. oxydans engineering bacteria for high efficiency production of 2-KLG. The G. oxydans is a strain commonly used in a first step fermentation process during two-step fermentation production of 2-KLG. The expression of sdh and sndh genes in G.oxydans can dissolve the dependence problem of small bacteria on associated bacteria, thus realizing direct conversion from D-sorbitol to 2-KLG, and simplifying the vitamin C production process. With a 2-KLG yield of 32.4g/L, the Gluconobacter oxydans gene engineering bacteria has very good application prospects.

The invention discloses a field separation method for tomicus piniperda-associated bacteria. The method comprises the following steps: determining a tomicus piniperda invasion hole on a suffered pine tree in a forest, peeling off the surface bark of the mother gallery of tomicus piniperda pests along the direction of the mother gallery of the tomicus piniperda pests by taking the invasion hole as an origin, so as to expose the phloem tissues of the eaten mother gallery of the tomicus piniperda, if larvae galleries are already formed at the both sides of the mother gallery, exposing the larvae galleries, inspecting and confirming whether the spores, hyphae, perithecia and blue-stain phloem tissues of tomicus piniperda-associated bacteria exist in the various eaten galleries of the tomicus piniperda, and adopting corresponding separation measures for the tomicus piniperda-associated bacteria according to the growth and development progresses and the blue-stain phloem tissue conditions of the tomicus piniperda-associated bacteria. The method disclosed by the invention integrates field sampling with laboratory strain separation, and is simple in steps and convenient to operate; the separation obtaining success rate of the tomicus piniperda-associated bacteria is high; the many links of bringing the wood blocks infected by the associated bacteria or the phloems with galleries, and the blue-stain tissues back to a laboratory at first, and then separating are effectively simplified, the separation time for the associated bacteria is saved, the separation is accurate, and the separation efficiency is increased.

The invention provides hydrophobic self-cleaning resin slurry, a hydrophobic self-cleaning resin dental material and application of the resin slurry and resin dental material, and relates to the technical field of oral materials. The hydrophobic self-cleaning resin slurry provided by the invention is prepared from the following raw materials: a dimethacrylate monomer, triethylene glycol dimethacrylate, perfluoroalkyl acrylate, a diluent, nano silicon dioxide, gamma-methacryloyloxypropyltrimethoxysilane, camphorquinone and a light curing accelerator. The perfluoroalkyl acrylate is added, so that the surface energy of the material is reduced. By introducing nano silicon dioxide, the mechanical property of the resin is improved, the microscopic roughness of the resin is increased, a lotus-leaf-like hydrophobic micro-nano hierarchical structure is constructed, the hydrophobic surface of the micro-nano structure can retain air, an air layer is formed on the surface of the material, and the contact area with protein and bacteria is reduced. Therefore, the adhesion of related bacteria in the oral cavity and the formation of bacterial biofilms are inhibited, and the material has excellent self-cleaning biological decontamination performance.
