(EP1010754-A1)      NOVELTY - A microorganism (1) being nonhemolytic, such as Bacillus sp. OYK-01-600 (FERM BP-6394) bacteria, and having antimicrobial activities against toxic bacteria, is new.    DETAILED DESCRIPTION - The microorganism (1) has a volume 4 times or more than that of a standard hay bacillus (IFO3134 ), has no induction period at the beginning of cultivation, and immediately initiates exponential growth such that, for example 103 /ml of microorganisms will become 107/ml in 4hr. Therefore the metabolic energy generated by growth is 10000 times or more that of the standard hay bacillus. (1) has antimicrobial activities against toxic bacteria such as Staphylococcus aureus, including methicillin-resistant Staphylococcus acureus, pathogenic Escherichia coli including O-157, Leginonella pneumophilia, Klebsiella pneumoniac, etc. (1) is at least one bacteria selected from Bacillus sp.OYK-01-600 (FERM BP-6394), Bacillus sp.OYK-03-600 (FERM BP-6395) and Bacillus sp.OYK-04-000 (FERM BP-6396).    USE -   The microorganism (1) is used for producing compost.    ADVANTAGE -   A difference in growth rate can inhibit bacteria that emit an offensive odor and many other noxious infectious bacteria. When used for the production of compost, a rapid temperature rise in a fermentation tank caused by the initial heat generation facilates the production of full- ripe compost.
