The invention discloses a method for preparing bacillus natto culture by using distiller's grains and its application, which belong to the technical field of fermentation engineering. The method comprises the following steps: bacterial species activation, primary seed culture, distiller's grains pretreatment, preparation of a fermentation medium, and solid fermentation to obtain the bacillus nattoculture. In the fermentation process of the present invention, the solid-state fermentation is used to produce bacillus natto. The entire fermentation process follows aseptic operation procedures, which enables solid-state culture production of bacillus natto to achieve pure-type culture and large-scale amplification production. The fermentation medium related to the invention solves the problemsof low number of viable bacteria existing in the fermentation with the distiller's grains as a main raw material, solves the problems of easy contamination of miscellaneous bacteria in liquid culture, low nutrient utilization rate, and difficult separation of bacteria and metabolites, and can greatly increase the yield of the bacillus natto.
