Embodiment 1

[0035] Prepare the culture medium, the composition is the glucose of 20g / L, the potato of 50g / L and the yeast extract of 10g / L.

[0036] Gluconobacter oxydans with the preservation number CGMCC NO.8039 was inoculated and cultured in the above-mentioned medium until the cell concentration reached 10 9 CFU / mL to obtain bacterial agent.

[0037] A typical colony diagram of this strain is shown in figure 1 and figure 2 shown.

Embodiment 2

[0039]Use Gluconobacter oxydans with the preservation number CGMCC NO.8039 to treat Botrytis cinerea, Botrytis cinerea, Plasmopara uiticola (Berk.dt Curtis), grape powder Uncinula necator, Penicillium expansum, Botrytis cinerea, Penicillium expansum (Link) Thom, Gloeosporium piperatum, Fusarium oxysporum f.sp. Lycopersici Snyder et Hansen), Monilinia fructicola, Monilinia laxa, Monilinia fructigena, Monilinia fructicola, Aspergillus niger ( Aspergillus niger), P.digitatum (Fr.) Sall, Penicillium italicum, and Fusarium oxysporum, and Caenorhabditis elegans and / or southern root Knot nematode (Meloidogyne incognita) was tested for antibacterial effect, and the results shown in Table 1 were obtained.

[0040] Among them, postharvest peach brown rot fungus, apple postharvest gray mold fungus, and apple postharvest penicillium fungus were selected as indicator fungi, and plate confrontation culture method and fruit in vivo artificial punching inoculation method were adopted.

Abstract

The invention discloses Gluconobacter oxydans strain, the preservation number of the strain is CGMCC NO.8039. On the other hand, the invention also provides a bacteria agent, wherein the bacteria agent contains live bacteria of the Gluconobacter oxydans strain and a culture medium. On the other hand, the invention also provides the application of the Gluconobacter oxydans strain and / or the bacteria agent in the prevention and treatment of diseases of fruits. In another aspect, the invention also provides a method for prevention and treatment of diseases of fruits, and the method includes contact of the bacteria agent of the live bacteria of the Gluconobacter oxydans strain with the fruits. Through the technical proposal, the Gluconobacter oxydans strain can effectively realize the prevention and treatment of diseases of fruits, and is free of residue of harmful chemical substances.
