Micro-ecological complex bacterial agent and method of preparing micro-ecological complex bacterial agent

The invention relates to a micro-ecological composite fungus preparation and a method for preparing the same, in particular to a micro-ecological preparation and a method for preparing the same. The method solves the problems that the prior micro-ecological preparation can only temporarily increase and supplement the amount of probiotics in intestinal canal of a human body in a short period, and has poor competitiveness and viability so that the probiotics are used up after a period of time of stopping taking the micro-ecological preparation. The micro-ecological composite fungus preparation mainly comprises bacillus natto, lactic acid kluyveromyces, lactobacillus acidophilus and soybean oligosaccharides. The method comprises the following steps: culturing micro-ecological funguses; intermediately culturing the micro-ecological funguses; culturing and centrifuging the micro-ecological funguses after the micro-ecological funguses are transferred into a high concentration culture fluid; and adding auxiliary materials to the micro-ecological funguses, pre-freezing and vacuum freeze-drying the mixture, and adding the soybean oligosaccharides to the mixture to obtain the micro-ecological composite fungus preparation. The total number of viable beneficial bacteria in the micro-ecological composite fungus preparation is between 1.0 x 10 and 9.9 x 10 per gram, the micro-ecological composite fungus preparation not only has huge unit number, but also has high survival rate of the viable bacteria of more than 98 percent two years later.
