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...

Problems solved by technology

However, almost all bacteria can generally survive under low temperature conditions, which greatly increases the chance of contamination by miscellaneous bacteria, which will cause serious damage to the target flora, thereby reducing the number of viable bacteria and performance of the target flora

At the same time, the equipment required by the freeze-drying method is expensive, the operation is complicated, and the cycle is long, so it is not suitable for industrial production.

In addition, there is a high-temperature spray-drying method, but because the higher temperature will not only kill the miscellaneous bacteria, but also kill the target flora
