specific Embodiment approach 1
[0019] Specific embodiment 1: A strain of Pseudomonas mediterranea MJM-3 in this embodiment is preserved in the General Microbiology Center of China Microbiological Culture Collection Management Committee, and the preservation address is No. 1, Beichen West Road, Chaoyang District, Beijing No. 3, the deposit date is June 26, 2012, and the deposit number is CGMCC NO.6292.
[0020] In this embodiment, Pseudomonas mediterranea (Pseudomonas mediterranea) MJM-3 is a Gram-negative bacterium, which forms round, opaque, light yellow, smooth protrusions, neat edges, and sticky colonies on the ADF medium (such as figure 1 shown).
[0021] Perform Gram staining, catalase, methyl red, acetylmethylmethanol, starch hydrolysis, indole, citrate on the isolated strain MJM-9 according to the Manual for the Identification of Common Bacterial Systems and the Berger's Handbook of Bacteria The detection and identification of physiological and biochemical experiments. The results showed that Pseud...
specific Embodiment approach 2
[0024] Embodiment 2: A strain of Pseudomonas mediterranei of this embodiment is used as bacterial fertilizer for crop cultivation.
[0025] The Pseudomonas mediterranea MJM-3 of this embodiment has ACC deaminase activity, produces plant growth hormone IAA, and synthesizes siderophiles; it can effectively promote plant nutrient absorption and regulate plant nutrition in a saline-alkali stress environment. Growth and improve the ability of plants to resist stress under adverse conditions. Its application in crop cultivation can improve fertilizer efficiency and increase yield.
[0026] The Mediterranean Pseudomonas (Pseudomonas mediterranea MJM-3) of this embodiment can inhibit or alleviate the adverse effects of plant diseases on plants by indirectly secreting siderophores, etc., and directly stimulate and regulate plant hormones by producing plant hormones and enzymatically reducing ethylene levels. Growth. The PGPR of the 1-aminocyclopropane-1-carboxylic acid (1-aminocyclopr...
