PROBLEM TO BE SOLVED: To provide a microbial preparation used for purification of water quality, decomposition of sludge, soil improvement or the like which does not require a large-scale apparatus, has excellent dispersibility and can be used simply and quickly, and in which sulfur bacteria are carried stably so as to exert purification capability.SOLUTION: There is provided a powdery microbial preparation in which a carrier containing neutral porous particles having a particle size of 50 μm or less by 70 vol.% or more is allowed to carry sulfur bacteria. Further, there is also provided a bag-shaped microbial preparation in which silica sand and white sand are mixed into the powdery microbial preparation, and which is encapsulated into a bag having water permeability. |
