Occurrence and genetic diversity of prophage sequences identified in the genomes of L. casei group bacteria.

ABSTRACT: It is widely believed that microorganisms belonging to L. casei group can have positive effects on the human body. Therefore, these bacteria are used in many industrial processes, including the production of dietary supplements and probiotic preparations. When using live microorganisms in technological processes, it is important to use those without phage sequences within their genomes that can ultimately lead to lysis of the bacteria. It has been shown that many prophages have a benign nature, meaning that they don't directly lead to lysis or inhibit microbial growth. Moreover, the presence of phage sequences in the genomes of these bacteria increases their genetic diversity, which may contribute to easier colonization of new ecological niches. In the 439 analyzed genomes of the L. casei
