Study of the influence of antagonist cultures on the development of technically harmful microorganisms during the production and subsequent storage of fermented dairy products

In the article there are the results of studies of the antagonistic cultures: lactobacilli and propionic acid bacteria. We studied the their influense on the development of technically harmful microorganisms during the production and subsequent storage of fermented dairy products (sour cream and cottage cheese). It was established that the investigated lactic acid bacteria and propionic acid bacteria strains had exhibited antagonistic activity to technically harmful microorganisms in dairy raw materials, during the production and storage of sour cream and cottage cheese. It has been shown that antagonistic activity is a strain-specific characteristic and depends on the antagonist culture inoculation dose and can manifest itself at different stages of the technological process.
