Isolation and Characterization of a New Lactobacillus delbrueckii ssp. bulgaricus Temperate Bacteriophage
lacbacillus bacteriophage
2008/3/28
Lactobacillus delbrueckii ssp. bulgaricus strain CRL 539 was shown to be lysogenic and inducible with mitomycin C. The conditions were determined for an optimal induction of temperate bacteriophage lb...
Bacteriophage Resistance in Lactococcus lactis Engineered by Replacement of a Gene for a Bacteriophage Receptor
phage resistance bacteriophage pip gene replacement
2008/3/27
The objective of this study was to construct a food-grade, phage-resistant strain of Lactococcus lactis by replacing a specific chromosomal gene with an allele that had been mutated in vitro. Lactococ...
Incidence of Inducible Bacteriophage in Lactobacillus helveticus Strains Isolated from Natural Whey Starter Cultures
Lactobacillus helveticus lysogeny bacteriophage starter cultures
2008/3/27
We studied the incidence of inducible Lactobacillus helveticus strains among 74 isolates from natural whey starter cultures that are used for the production of Italian Grana and Provolone cheeses. Mit...
Effect of Dilution Rate on Bacteriophage Development in an Immobilized Cell System Used for Continuous Inoculation of Lactococci in Milk
Lactococcus lactis ssp. lactis bacteriophage immobilized cells continuous fermentation
2008/3/25
The response to bacteriophage contamination of a free cell and an immobilized cell bioreactor was studied during continuous pH-controlled fermentation of milk with Lactococcus lactis ssp. lactis. Afte...
Conductimetric Analyses of Bacteriophage Infection of Two Groups of Bacteria in DL-Lactococcal Starter Cultures
bacteriophage analysis conductance indirect conductance method starter culture activity
2008/3/22
Two conductimetric methods were used for simple and rapid detection of bacteriophages against the two major groups of bacteria in DL-lactococcal, mixed-strain starter cultures. Bacteriophages against ...
