title: Lipopolysaccharide is the receptor for kappa phage in Serratia marcescens.
abstract: Kappa phage active on Serratia marcescens can form plaques on white and red strains with identical efficiencies. To identify the kappa phage receptor, the inactivation of the phage was studied after incubation with several bacterial subcellular fractions. The experiments demonstrated that kappa phage adsorbs to outer membrane fractions of susceptible cells. Proteinase K did not affect the rate of inactivation. Lipopolysaccharide proved to be the primary receptor for kappa phage. Prodigiosin content of the lipopolysaccharide fraction was low.
