MOLECULAR-GENETIC DETECTION OF BACTERIOPHAGES AND PHAGE ASSOCIATIONS IN RAW MATERIALS, INDUSTRIAL MEDIA, AND DAIRY PRODUCTS SAMPLED AT DAIRY-PROCESSING PLANTS OF THE REPUBLIC OF BELARUS
Abstract
A total of 183 samples of dairy raw materials, industrial media, and fermented dairy products collected from dairy-processing enterprises of the Republic of Belarus were examined. Among phagepositive samples, 36.1 % contained lactophages of the 936 group, 25.1 % contained lactophages of the C2 group, and 19.1 % contained lactophages of the P335 group. Of the four bacteriophage groups infecting Streptococcus thermophilus, the cos group was the most prevalent (7.65 % of samples), followed by the 5093 group (3.28 % of samples), while bacteriophages of the pac and 987 groups were detected in 1.09 % and 1.63 % of samples, respectively. Phage associations comprising two to five types of lactic acid bacterial phages were identified in 60.5 % of the analyzed samples. The species composition of bacteriophages in different categories of fermented dairy products was analyzed.
