NOVELTY - An antagonistic bacteria for preventing and treating bacterial wilt of continuously planted tobacco comprising strain NJL-25 and strain NJL-14, is new.    USE - The antagonistic bacteria is useful for preventing and treating bacterial wilt of continuously planted tobacco and producing microorganism organic fertilizer (all claimed).    ADVANTAGE - The antagonistic bacteria can quickly propagate to form dominant group in the soil after the organic fertilizer is applied into the soil; and the product can reach greater than 97.6% of biological preventing and treating rate on the bacterial wilt in the soil affected by the bacterial wilt of the tobacco.    DETAILED DESCRIPTION - An antagonistic bacteria for preventing and treating bacterial wilt of continuously planted tobacco comprising strain NJL-25 and strain NJL-14, where the strain NJL-25 belongs to Brevibacillus brevis, preserved in General Microorganism Center of China Committee for Culture Collection of Microorganism in July 9, 2009; the preservation number of the strain NJL-25 is CGMCC NO. 3175; the major biological characters of the NJL-25 strain comprises: gram-positive, the cell is represented as rod; the intumescent sporocyst contains elliptic spores; the colony is smooth and it is bred in a strictly aerobic environment; the catalase is negative and the V.P. reaction is negative, and the methyl red test is negative; the processes of fermenting sucrose, fructose, mannitol and sorbitol generate acid but not generate gas; nitrate reductase is negative, the amylohydrolysis is negative, the gelatin hydrolysate is positive, and the decompressed casein is positive; it not generates sulfureted hydrogen but generates indole; the proper growth temperature is at 30 degrees C and the proper pH is at 7.0; the strain NJL-14 belongs to Bacillus cereus, preserved in General Microorganism Center of China Committee for Culture Collection of Microorganism in July 10, 2009; the preservation number of the strain NJL-25 is CGMCC NO. 3174; the major biological characters of the NJL-25 strain include the follows: gram-positive, the cell is represented as rod; the porocyst is not remarkably intumescent; the spores are round or columnar ones which are secundair or nearly secundair; the surface of the strain is rough; the strain is flat and irregular; it is of facultative aerobic growth; the catalase is positive and the V.P. reaction is positive, and the methyl red test is positive; the processes of fermenting glucose, sucrose, fructose, maltose and sorbitol generate acid but not generate gas; nitrate reductase is positive, the amylohydrolysis is positive, the gelatin hydrolysate is positive, and the decompressed casein is positive; it not generates sulfureted hydrogen and indole; the proper growth temperature is at 30 degrees C and the proper pH is at 7.0, is new. INDEPENDENT CLAIMS are:    (1) a microorganism organic fertilizer produced by the antagonistic bacteria for preventing and treating bacterial wilt of continuously planted tobacco; and    (2) a method for producing the microorganism organic fertilizer for preventing and treating bacterial wilt of continuously planted tobacco comprising: (a) respectively inoculating the antagonistic bacteria NJL-25 and NJL-14 proposed into the potato dextrose agar (PDA) culture medium; producing the antagonistic bacteria by liquid fermentation until the number of bacteria or spores in the fermenting liquid is not lower than 1x1010 pieces/ml under the following conditions: initial pH value is at 7.0-7.2, the fermentation temperature is at 30 degrees C, by dissolved oxygen; the ventilation range is 30-100% and stirring speed is at 170 rpm to obtain spores on the latter middle stage of the fermentation; (b) inoculating the NJL-25 and NJL-14 fermenting liquid into the rotten pig manure compost and microorganism decompressed mixture of the vegetable bran by amount of 50 L/ton, and performing solid fermentation to the NJL-25 and NJL-14 fermenting liquid at 30-50 degrees C; during fermenting, turning the stack once every day; fermenting the NJL-25 and NJL-14 fermenting liquid for 5-7 days until the contents of both antagonistic bacteria NJL-25 and NJL-14 are greater than 1x108 pieces/g to obtain solid bacteria of antagonistic bacteria NJL-25 and NJL-14; (c) by the rotten pig manure compost and the microorganism decompressed mixture solid bacterium of vegetable bran, mixing the antagonistic bacterium NJL-25 solid bacterium and the NJL-14 solid bacterium at ratio of 1:1 by volume to obtain solid mixing bacterium of the rotten pig manure compost and solid mixing bacterium of the microorganism decompressed mixture solid bacterium of vegetable bran; and (d) completely mixing the solid mixing bacterium of the rotten pig manure compost and solid mixing bacterium of the microorganism decompressed mixture solid bacterium of vegetable bran at ratio of 50-70%: 30-50% by volume; after-ripening the mixture for 2-3 days; meanwhile, turning the stack for twice; evaporating the microorganism organic fertilizer at a temperature not greater than 60 degrees C until the water content is lower than 30%; packaging the microorganism organic fertilizer; and discharging the microorganism organic fertilizer out of the factory to obtain the needed microorganism organic fertilizer capable of preventing and treating bacterial wilt of continuously planted tobacco.
