NOVELTY - A microorganism having the efficiency of removing offensive odor from organic waste is new.    USE - The microorganism and microbial agent are useful for fermenting organic waste. The microorganism and agent are useful for preventing or removing an offensive odor from organic waste. The microorganism is useful for producing an insecticide, microbicide, preservative, feed additive, fermented food, and probiotic agent, preventing decomposition, and promoting digestion and fermentation.    DETAILED DESCRIPTION - A microorganism is selected from Saccharomyces exiguous SJP6728AF1 (KCCM-1 0675P), Saccharomyces exiguous SJP6729AF2 (KCCM-10677P), Candida fructus SJP6730AF3 (KCCM-10679P), Candida zeylanoides SJP6840AF4 (KCCM- 10695P), Kazachstania aerobia SJP6844AF5 (KCCM-10696P), Candida humilis SJP6726AF6 (KCCM-10697P), Candida zeylanoides SJP6843AF7 (KCCM-10698P), Lactobacillus paraplantarum SJP66722A5 (KCCM-10676P), Bacillus badius SJP673161 (KCCM-10680P), Paenibacillus lactis SJP6732B2 (KCCM-10726P), Paenibacillus sp. AY397772 SJP6719B3 (KCCM-10727P), Brevibacillus borstelensis SJP6734B4 (KCCM-10728P), Paenibacillus polymyxa SJP6735B6 (KCCM-10678P), Lactobacillus casei SJP6841L2 (KCCM-10729P), Lactobacillus brevis SJP6720L3 (KCCM-1510730P), Leuconostoc citreum SJP6723L4 (KCCM-10731P), or Camobacterium maltaromaticum SJP6742L5 (KCCM-10732P). INDEPENDENT CLAIMS are:    (1) a microbial agent, for the fermentation of organic waste, containing one or more microorganisms cited above;    (2) an agent, for preventing or removing an offensive odor from organic waste, containing one or more microorganisms cited above;    (3) an insecticide or microbicide containing one or more microorganisms cited above;    (4) a preservative or a feed additive containing one or more microorganisms cited above;    (5) a method for preparing a fermented food which comprises fermenting a food using one or more microorganisms cited above;    (6) a fermented food prepared by the method of (5), which contains one or more microorganisms cited above; and    (7) a probiotic agent containing one or more microorganisms cited above.
