Microbial compound preparation and preparation method thereof

Abstract

The invention relates to a microbial compound preparation containing Lactobacillus acidophilus and a processing technology thereof. The microbial compound preparation contains a Lactobacillus acidophilus fermentation culture; the Lactobacillus acidophilus is taken as an active ingredient; and the viable count of the Lactobacillus acidophilus in the microbial compound preparation is more than 7.7*10<10>cfu/g, and the average particle size is less than 10mu m. The Lactobacillus acidophilus fermentation culture is obtained by culturing in a fermentation culture medium containing 3 to 5 percent of porous starch, 4 to 5 percent of defatted milk powder, 5 to 7 percent of defatted soybean powder, 4 to 6 percent of tapioca flour, 3 to 5 percent of papaya powder, 1 percent of glutamic acid soda, 1to 2 percent of glucose, and 0.8 percent of table salt. Production processes are simple, and production cost is low. The microbial compound preparation can be prepared into medicinal preparations, health-care products, foods and nutritional supplements, can be taken as a core functional ingredient in feed additives, and has a broad application range.

Description

technical field [0001] The invention relates to a microbial compound preparation and a preparation method thereof, in particular to a microbial preparation containing Lactobacillus acidophilus and a preparation method thereof. belongs to the field of microbiology. Background technique [0002] Lactobacillus acidophilus belongs to the genus Lactobacillus, Gram-positive, does not produce spores, does not move, has no flagella, exists in single, double or short chain form, and can ferment sugar to produce lactic acid and ethanol , hydrogen peroxide and other anaerobic or facultative anaerobic microorganisms. The G+C content is 36.0%-37.4%, the optimum pH is 5.5-6.0, the optimum growth temperature is 35-38°C, basically no growth below 20°C, poor heat resistance, can use glucose, fructose, lactose, sucrose for homozygous fermentation , producing DL-type lactic acid. Lactobacillus acidophilus is one of the main microbial species in the intestinal tract of humans and animals. It...
