Bacteriophages play important roles in ecological processes such as nutrient cycling, horizontal gene transfer, and microbial evolution. Despite being the most numerous biological entities on the planet, there are relatively few fully sequenced phage genomes in publicly available databases. While phage communities have been studied in a variety of ecosystems, the genetic and phenotypic diversity present on Earth has yet to be fully explored. We recently isolated four Pseudomonas aeruginosa infecting phages, three from inland freshwater lakes and a fourth from soil. Here we present the characterization of these environmental phages, including the complete genome sequence, growth characteristics, and morphology. Comparisons with characterized genomes as well as metaviromic sequences from similar ecosystems provide insight into the pervasiveness of our four isolates.
