Abstract
The article presents the results of analytical and experimental studies of the influence of the process of their immobilization in the structure of bacterial nanocellulose (BNC) on the vital activity of lactic acid bacteria. The work used a starter culture of acidophilus bacillus in skim milk and bacterial nanocellulose obtained by static cultivation of a symbiotic culture of Medusomyces gisevii in a semi-synthetic nutrient medium. It has been established that adding more than 5% BNC leads to the formation of a clot already at the sterilization stage, so you should either add less than this dosage or change the method of adding BNC. Immobilization of acidophilus bacteria on BNC does not increase the number of bacteria, but stimulates their acid formation. Cultivation for more than 3 days is impractical, because both the acidity and the number of microorganisms begin to decrease after this time, and on the 7th day no viable cells are detected in the samples.
