This invention relates to an antimicrobial peptide and its applications. The amino acid sequence of the antimicrobial peptide is at least one of the sequences shown in SEQ ID No. 1 to SEQ ID No. 8. The antimicrobial peptide exhibits excellent broad-spectrum antimicrobial activity, for example, against Acinetobacter spp. (…). Acinetobacter ), Pseudomonas aeruginosa ( Pseudomonas aeruginosa ) and Bacillus spp. ( Bacillus This bacterium possesses antibacterial activity. Against the backdrop of increasingly severe global bacterial resistance and the gradual ineffectiveness of traditional antibiotics against multidrug-resistant bacteria, this provides a new treatment option for carbapenem-resistant bacteria such as Acinetobacter baumannii, Pseudomonas aeruginosa, and Bacillus subtilis, which pose a significant threat to public health, and offers new possibilities for solving the clinical dilemma of "no available drugs."

Sb2-4, and belongs to the technical field of microorganisms. The endophytic acinetobacter (Acinetobacter sp.) Sb 2-4 is preserved in the China Center for Type Culture Collection on December 1, 2025, the preservation number is CCTCC NO: M20252724, and the 16S rRNA sequence is shown as SEQ ID NO.1. The endophytic acinetobacter can be used for degrading diethyl phthalate, dibutyl phthalate and butyl benzyl phthalate at the same time, and the effect of a biological treatment means of PAEs is improved.

The invention provides a group of growth promoting-decontamination flora and application thereof, and belongs to the technical field of phthalate polluted soil remediation. The growth promoting-decontamination flora comprises the following components: Acinetobacter sp. Sb < 2-4 >, Gordonia phtheria 107, Gordonia phtheria 107, Gordonia phtheria 19743, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia phtheria 109, Gordonia Wherein the endophytic acinetobacter Sb 2-4 is preserved in the China Center for Type Culture Collection on December 01, 2025, and the preservation number of the endophytic acinetobacter Sb 2-4 is CCTCC (China Center for Type Culture Collection) NO: M20252724.

The invention belongs to the technical field of environmental microorganisms and ecological restoration, and provides a barren-resistant acinetobacter, an agrobacterium tumefaciens, a complex microbial inoculant thereof and application of the complex microbial inoculant in promoting vegetation restoration of pinus tabulaeformis in mining areas, the preservation number of the barren-resistant acinetobacter YSR-01 is CGMCC No.35513, the preservation number of the agrobacterium tumefaciens YSP-02 is CGMCC No.35515, and the preservation dates of the acinetobacter and the agrobacterium tumefaciens are both August 4, 2025. The two strains are compounded to prepare the complex microbial inoculant. The microbial agent can effectively improve the nutrient condition of barren soil in a mining area through the synergistic effect of potassium and phosphorus dissolving, and growth of host plants (such as Chinese pines) is remarkably promoted due to the excellent barren resistance and colonization capacity of the microbial agent. Experiments prove that the growth promoting effect of mixed application of the two strains is obviously better than that of single application, and the method has important value for accelerating ecological reconstruction of mining areas.

The invention discloses a bacterial strain capable of efficiently degrading 2-MIB, the bacterial strain is Acinetobacter sp.FRL14566, the preservation number of the bacterial strain is GDMCC NO.66093, and the nucleotide sequence of the bacterial strain is as shown in SEQ ID No.1.
