Identification and Characterization of New Strains from Common Carp (), Potentially Possessing Probiotic Properties and Plastic Biodegradation Capabilities.

Finding and characterizing new bacterial strains, including probiotic strains, is a crucial task in today's world to expand the genetic data pool and identify new genes. In this study, we investigated the gut microbiota of one industrial species, , and identified representatives of various microbial genera, including , , , , and . Notably, we discovered two strains of with potentially probiotic properties. We conducted next-generation sequencing (NGS) of these strains, described their antibiotic resistance and antibacterial activity, and compared them with other representatives of the genus. These strains, characterized by rapid growth, the presence of the heat shock protein gene, and genes associated with microplastic degradation, provide a promising basis for further research, including studies on their potential application in plastic biodegradation.
