Genome sequence of the novel virulent bacteriophage PMBT14 with lytic activity against Pseudomonas fluorescens DSM 50090R
Psychrotrophic gram-negative Pseudomonas spp. represent a serious problem in the dairy industry as they can cause spoilage of milk and dairy products. Bacteriophages have moved into focus as promising biocontrol agents for such food spoilage bacteria. The virulent Siphoviridae phage PMBT14 was isolated on a mutant variant of P. fluorescens DSM 50090 challenged with an unrelated virulent P. fluorescens DSM 50090 Podoviridae phage (i.e., mutant strain DSM 50090R). PMBT14 has a 47,820-bp dsDNA genome with 76 predicted open reading frames (ORFs). Its genome shows no significant sequence similarity to that of known phages, suggesting that PMBT14 represents a novel phage. Phage PMBT14 could be a promising biocontrol agent for P. fluorescens in milk or dairy foods.
