NOVELTY - A sterile active culture solution is manufactured by immersing microorganism material such as waste material, soil, humus or animal excrement in magnetized water containing minerals. The immersed mineral material is treated by fault aeration process for 10-20 days using activated catalyst to elute decomposed substance from microorganism, thereby inducing proliferation of microorganism and its metabolites.    USE - As material for organic farming, waste water purification, environmental improvement material, material for green spaces, stock raising drinking water, insect repellent, for improving replant failure and feed additive.    ADVANTAGE - The sterile active culture solution has increased quality and can be stabilized and preserved for a long time. The active culture solution is not influenced by environmental or temperature change. The solution effectively deodorizes bad smells in poultry farms and pigsties.    DETAILED DESCRIPTION - A sterile active culture solution is manufactured by forming magnetized water by immersing rock or ceramic containing minerals and magnetism in water for 1-5 days. The microorganism material such as stock raising waste material, soil, humus or animal excrement is immersed in the treated water. The immersed mineral material is treated by fault aeration process for 10-20 days using rock or ceramic as activated catalyst and a decomposition organic substance is made to elute from microorganism in the waste materials. The proliferation of microorganism and its metabolites are induced.    An INDEPENDENT CLAIM is also included for an apparatus for manufacturing sterile active culture solution which is equipped with a diffusion tube for aeration. The diffusion tube is attached to mineral material unit and a permeable container filled with magnetized water which supplies mineral material into second aeration tank. The container supplies treated water into first aeration tank. The apparatus further comprises a microorganism material unit having a bag like container (water-permeable) filled with microorganism material such as waste, soil and humus.
