The invention discloses a method for preparing the anti-tumor compound Eupenifeldin and its special bacterial strain. The special bacterial strain for preparing the anti-tumor compound Eupenifeldin provided by the present invention is specifically Phoma sp. XZ068, and its preservation number in the General Microbiology Center of China Committee for the Collection of Microorganisms is CGMCC No. 10481. Experiments have proved that the present invention utilizes Phoma sp. (Phoma sp.) XZ068CGMCC No.10481 to prepare the method for the antitumor active compound Eupenifeldin, and the yield is high (the crude extract of 10.3g ethyl acetate obtains 400mg pure compound Eupenifeldin through separation and purification, The purity is more than 99%, and the yield is 3.9%), and the method of the invention is simple to operate, low in cost, time-saving and labor-saving.

The invention relates to a decahydronaphthalene compound and an application thereof. According to the invention, the decahydronaphthalene compound is separated and extracted from a fermentation liquidof a symbiotic and endophytic fungus Phoma sp. of Sinularia sandensis, wherein the decahydronaphthalene compound has T-cell subtype regulation activity, is low in cytotoxicity and can be used for preparing immunomodulatory drugs. The invention provides a lead compound for developing novel immunoregulatory drugs, opens up a new way for deep research and development of the novel immunoregulatory drugs, and facilitates development and utilization of marine medicinal resources.

The invention discloses a lilium regale germin-like protein gene LrGLP2 with antifungal activity. The gene LrGLP2 has the nucleotide sequence as shown in SEQ ID:1 and encodes germin-like protein. A relevant technology of functional genomics proves that the gene LrGLP2 has a function of improving the plant antifungal activity. The antifungal gene LrGLP2 is constructed to a plant expression vector and is transferred into tobacco to perform overexpression; and the transgenic tobacco plant has strong in vitro antifungal activity. The LrGLP2 transgenic tobacco protein has different degrees of inhibition effects on the growth of botryosphaeria dothidea, phomopsis fungi, fusarium oxysporum and botrytis cinerea.

The invention discloses a bacillus polymyxa strain and application thereof. The Bacillus polymyxa strain of the present invention, the Bacillus polymyxa strain is PBSZ123, the preserved name is Bacillus polymyxa (Paenibacillus polymyxa), and it is preserved in the General Microorganism Center (CGMCC) of China Microorganism Culture Preservation Management Committee, the depository unit The address is No. 3, Yard No. 1, Beichen West Road, Chaoyang District, Beijing. Date of deposit: August 14, 2019; Collection number: CGMCC No.18386. The bacillus polymyxa of the present invention is isolated from the endophyte of the polyphylla, and has a good inhibitory effect on the main pathogenic bacteria of the polyphylla, Botrytis cinerea, Phoma leaf spot, and Polychaete spp.

The invention discloses a method for synthesizing dialkylhydrogenated noppylbenzyl quaternary ammonium salt compounds and the antibacterial application of such compounds. The invention is obtained by directly synthesizing dialkylhydrogenated noppylamine and benzyl halides in one step Dialkylhydrogenated noppyl benzyl quaternary ammonium salt, in an organic solvent, dialkylhydrogenated noppylamine and benzyl halide (chlorine, bromine, iodine) are fed into a stirring bar and equipped with a certain material ratio respectively Condensate in the Erlenmeyer flask of the reflux device, heat to react, the reaction temperature is controlled at 100-150°C, and the reaction time is controlled at 1-3d. After the reaction, the product is filtered, washed, recrystallized and vacuum-dried to obtain 7 kinds of dialkylhydrogenated notylbenzyl quaternary ammonium compounds respectively, and 7 kinds of dialkylhydrogenated notylbenzyl quaternary ammonium Both Phoma citri and Anthracnose citrus had good inhibitory effect. The invention has rich raw materials, simple operation, mild reaction conditions and simple post-purification treatment. Compared with traditional antibacterial agents, this type of antibacterial compound has the advantages of simple structure, safety and non-toxicity, less environmental pollution, etc., and has a good application prospect.
