Although membrane-containing dsDNA bacterial viruses are some of the most prevalent predators in aquatic environments, we know little about how they function due to their intractability in the laboratory. Here, we have identified and thoroughly characterized a new type of membrane-containing bacteriophage, Jorvik, that infects the freshwater mixotrophic model bacterium Rhodobacter capsulatus. Jorvik is extremely virulent, can persist in the host integrated into the RuBisCo operon and encodes two experimentally verified cell wall hydrolases. Jorvik-like prophages are abundant in the genomes of Alphaproteobacteria, are distantly related to known viruses of the class Tectiliviricetes, and we propose they should be classified as a new family. Crucially, we demonstrate how widely used phage manipulation methods should be adjusted to prevent loss of virus infectivity. Our thorough characterization of environmental phage Jorvik provides important experimental insights about phage diversity and interactions in microbial communities that are often unexplored in common metagenomic analyses. Jorvik is a circular dsDNA membrane-containing phage distinct from model phage PM2 Jorvik-like prophages are abundant in genomes of Alpha-proteobacteria Host regulator CtrA and recombinase XerCD are likely required for the life cycle Spontaneous lytic variant clears host cultures at multiplicity of infection <0.01 Virology; Ecology; Microbiology
