(CN1346883-A)   NOVELTY - Preparing (M) high density antagonistic microbe base material comprises: (a) inoculating a mixture of native microbes (as main components) to an organic medium containing rice bran to obtain crude bacteria by subculture; (b) inoculating the crude bacteria in a culture medium consisting of crushed soil from volcanic rocks/minerals, combined nutrients and water; and (c) culturing and subjecting to air ventilation along with rise in temperature.    USE - (M) Is useful for preparing high density antagonistic microbe base material for use in soil improvement. The base material speedily prevents damages by fungi of soil, for e.g. wilt including bacterial wilt. The base material can be used alone and/or in combination with other typical organic fertilizers to scatter and/or initial manure to distribute over a wide area to be treated. The base material imparts harmony between different microbes in soil and recovering performance and healthy environments of soil, and also accelerates the formation of nutrient from organic materials and to prevent contamination of rivers and/or lakes. The base material is employed in the waste of livestock industry, to reduce the bad odor and is also utilized as a manure and/or compost including night soil.    DETAILED DESCRIPTION - Preparing (M) high density antagonistic microbe base material (M) comprises:    (a) inoculating a mixture or native microbes including Actinomycetes of Streptomyces genus, bacteria of Corynebacterium, filamentous fungi of Aspergillus genus and yeast of Saccharomyces genus as main components to organic medium containing rice bran as principle ingredient to obtain crude bacteria by subculture;    (b) inoculating the obtained crude bacteria in a culture medium consisting of crushed soil from volcanic rocks/minerals, combined nutrients and water;    (c) culturing for a desired period and then being subjected to air ventilation under agitating the cultured material along the rise in temperature.    An INDEPENDENT CLAIM is also included for an high density antagonistic microbe base material prepared by (M).
