NOVELTY - Producing microbial bio-organic fertilizer, by inoculating fermentation broth comprising NJN-6 strain on mixture comprising puffed feathers, rapeseed compost and pig manure compost, fermenting mixture, subjecting microbial NJN-6 solid inoculum to evaporation process and packaging obtained bio-organic fertilizer, where the NJN-6 is a Bacillus subtilis (CGMCC NO: 3183).    USE - The method is useful for producing microbial bio-organic fertilizer used for promoting growth of banana and controlling wilt disease and various soil-borne diseases of banana (all claimed).    ADVANTAGE - The method enables production of microbial bio-organic fertilizer having high content of beneficial amino acids. The cost of the microbial bioorganic fertilizer is saved by 32%. The microbial bio-organic fertilizer provides good beneficial effect.    DETAILED DESCRIPTION - Method for producing microbial bio-organic fertilizer, involves (a) inoculating 50 l/ton fermentation broth comprising NJN-6 strain and having bacterial content of 1x 108 colony-forming units (cfu)/g or more on mixture comprising 10% puffed feathers, 10% rapeseed compost and 80% pig manure compost, subjecting obtained mixture to composting or solid fermentation process for 7-9 days, turning fermentation mixture daily, and monitoring temperature during the fermentation process such that temperature during the fermentation process should not exceed 50 degrees C and bacterial content of the NJN-6 strain in the fermentation broth reaches 1x 108 cfu/g or more after completion of the fermentation process to obtain microbial NJN-6 solid inoculum, and (b) subjecting the microbial NJN-6 solid inoculum to evaporation process at not greater than 60 degrees C until moisture content reaches 30% or less and packaging obtained bio-organic fertilizer, where the NJN-6 is a Bacillus subtilis (CGMCC NO: 3183), and the rapeseed compost is prepared by adding Stenotrophomonas maltophilia strain 37-1 (CGMCC NO: 1543) as fermentation strain to raw meal, adjusting water content of the meal to 55-65% and pH to 6-7.5, subjecting the meal to an open solid fermentation process at 50 degrees C, turning the meal every day such that fermentation reactor is maintained at 35-50 degrees C for 5 days, adjusting pH and moisture content of obtained acid containing fermented mixture after each time turning process to 6-7 and 55-65% respectively, spraying acid on the fermented mixture until pH of the fermentation mixture is adjusted to 5, performing low-temperature drying or natural drying process and obtaining microbial hydrolyzate as rapeseed compost. An INDEPENDENT CLAIM is included for microbial bioorganic fertilizer produced by the above-mentioned method.
