Product Specifications

Lactobacillus acidophilus content ≥1.0*10¹¹CFU/g, powder, moisture ≤7%

Strain characteristics

Isolated from healthy human intestinal tract, acid production, osmotic pressure resistance and other biological characteristics.

Source of strain

Lactobacillus acidophilus was collected from Guangxi, Tibet, Yunnan and other regions, and a variety of Lactobacillus series strains were screened out by sampling the soil around the living areas and food of local residents.

Colony morphology

1. Under the electron microscope, the size of the cells is generally 0.6~0.9*1.5~6.0μm, and they are arranged in single, double or 2-3 short chains. The thalli are usually slender rod shaped, without flagella and without movement.

2. On MRS Medium, the colonies formed were small, with smooth edges, raised and smooth surfaces, twinkling with oil, and the colonies were opaque and did not produce pigment.

Growth characteristics

1.the suitable growth temperature is 35~38℃, 20℃ no growth, high growth temperature 43℃~48℃, poor heat resistance; The suitable pH is 5.5~6.0, the initial growth pH is 5.0~7.0, acid resistance is strong, can grow in the environment where other lactic acid bacteria can not grow.

2. Lactobacillus acidophilus has a particularly strong ability of acid and bile salt resistance. When the bile salt concentration is 0.3% and pH value is 2.0, the survival rate of Lactobacillus acidophilus can reach 62.2%. Lactobacillus acidophilus has obvious permeability resistance, and its maximum tolerance concentration is 9% NaCI.

3. Culture in the laboratory, MRS Medium can be used for culture.

4.Biochemical characteristics: Lactobacillus acidus growth and reproduction need certain vitamins, folic acid and other growth factors, the most suitable growth temperature culture growth is slow, long production cycle; Protein resolution is weak and the rate of producing acid in milk is low, mainly due to its incomplete proteolytic enzyme system, REDOX potential and trace elements. The growth of Lactobacillus acidophilus can be promoted by adding substances that reduce REDOX potential and growth promoting substances to milk.

Scope of application

It is suitable for people of all ages except infants. Dosage: 10 billion CFU per person/day.

Storage & Shelf Life

Store in a cool and dry place (sealed), or refrigerate below 4℃, shelf life is 24 months.

Packing specification: 1KG/ bag, 25 kg/barrel
