The acceptor phage is a lytic phage comprising a synthetic genome wherein the target gene of interest is flanked by recombinase sites. The acceptor phage infects a first host bacteria expressing a recombination plasmid facilitating recombination. The phages then infect a second host bacteria expressing a counterselection system that accumulates recombined phage variants and selecting against non-recombined phages. The accumulated phage variants infect a third host bacteria. The phage library may then be sequenced and characterized.
