Characterization of two psychrophilic Pseudomonas bacteriophages isolated from ground beef.
Characterization studies were performed on two psychrophilic phages which were isolated from ground beef samples. Phage inactivation by exposure to heat, low pH, osmotic shock conditions, and freezing showed that these two isolates were different. One-step growth experiments indicated that one isolate had a burst size five times as large (500) and a latent period two times as long (4 hr) as the...
متن کاملSusceptibility of psychrotrophic pseudomonads of milk origin to psychrotrophic bacteriophages.
A total of 47 psychrotrophic pseudomonads isolated from raw milk came from Newfoundland (19 isolates), British Columbia (6 isolates), Ontario (19 isolates), and Cork, Ireland (3 isolates). The susceptibility of these was tested against 30 bacteriophages isolated from cold-storage beef. Distinct lysotypes were observed with isolates representing different geographic regions. Phages as agents in ...
متن کاملcontrol of brochothrix thermosphacta in pork meat using lactococcus lactis subsp. lactis i23 isolated from beef
this study evaluated the antimicrobial activities of two lactic acid bacteria, lactococcus lactis subsp. lactis i23 and lactococcus lactis subsp. lactis e91, against brochothrix thermosphacta in pork meat during storage at ambient temperature (30°c) for 168 h. the lab strains and the spoilage organism were inoculated on fresh pork samples at 1×106 cfug-1. results showed about 3 log reduction in...
متن کاملMetagenomics of Bacteriophages Isolated from Marine Sediments
Results: The modified method for bacteriophages isolation and purification developed in this work resulted in high concentration of viral particles, which was confirmed by electron and fluorescent microscopy. Some phages were observed to have unusually long tails, up to 1 μm in length. It is possible that this is the result of high concentrations of EPS (the main component of bacterial biofilm)...
متن کاملT-related bacteriophages isolated from Shigella sonnei.
The properties of three T-related phages-35, 55, and 3201-isolated from Shigella sonnei were studied. They were similar with respect to morphology of plaques, duration of the latent periods, lysis inhibition effect, and serological characteristics. These phages closely resembled the T-even phages. Phages 3201, 35, and 55 had the same host range and receptor specificity as phage T2.
