Abstract:
:Sixty-three strains of lactic streptococci isolated from commercial lactic streptococcal starter cultures were examined for lysogeny by treatment with ultraviolet light or mitomycin C. After treatment with the inducing agent, all strains, whether or not they lysed, were examined for evidence of phage release by electron microscopy. Thirty-eight strains yielded intact phages or phage particles of varying morphology. All the temperate phages had isometric heads and noncontractile tails; some had collars and structurally distinctive baseplates. Indicator host strains were found for phages induced from seven different strains. Three strains that released phages spontaneously yielded titers of 10(3) to 10(4) plaque-forming units per ml. When strains that spontaneously released phages were grown in mixed culture with indicator strains, increased phage titers of 10(6) to 10(7) plaque-forming units per ml were observed. These findings indicate that lysogenic lactic streptococcal strains may serve as a reservoir for phages that attack sensitive strains in mixed- or multiple-strain lactic starter cultures.
