Method of treating organic waste, agent for treating organic waste and microorganisms to be used therein

Bacillus subtilis Bacillus pallidus There are provided a method of treating organic waste, which is excellent in the smooth temperature elevation in the early stage of the treatment and satisfactory in temperature-maintenance in a high temperature range, and by which the stable treatment of organic waste is achieved and the evaporation of moisture is promoted, thereby a stable effect of treating organic waste and an increased treatment scale being achieved; an agent for treating organic waste; and microorganisms to be used therein. The method is characterized by the use of a mesophilic bacterium showing its activity at 15 to 50° C. and a thermophilic bacterium showing its activity at 50 to 70° C. in the organic waste. As the mesophilic bacteria, bacteria which have an exothermic action and form spores under a temperature of 50° C. or higher are preferable and is more preferable. Among these bacteria, a C-3102 strain (FERM BP-1096) is especially preferable. As the thermophilic bacteria, is preferable and, among these bacteria, a TK6004 strain (FERM BP-08597) is more preferable.
