Abstract

This study reports on the identification and characterization of bacteriophages isolated from cheese-production facilities that use undefined, mixed starter cultures. Phage screening was carried out on whey samples isolated from 3 factories, 2 utilizing one particular undefined starter mixture and 1 utilizing another undefined starter mixture. Phage screening was carried out using 40 strains isolated from the 2 mixed starter cultures, and phages were profiled using host range, electron microscopy, multiplex PCR, and DNA restriction analysis. Twenty distinct lactococcal phages were identified based on host range and DNA restriction profiles, all belonging to the 936-type phage species. Nineteen of these phages were found to be able to infect both recognized subspecies of Lactococcus lactis. Restriction of phage DNA isolated using a newly developed guanidinium thiocyanate disruption method showed that the genomes of the 20 isolated phages were between 26 and 31 kb in size. It is evident from this study that the use of mixed starters creates an ideal environment for the proliferation of different phages with slightly varying host ranges. Furthermore, in this environment, members of the 936-type phage species clearly dominated the phage population.

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 July 2013.
All research outputs
#6,729,240
of 12,418,082 outputs
Outputs from Journal of Dairy Science
#3,777
of 7,220 outputs
Outputs of similar age
#61,322
of 147,464 outputs
Outputs of similar age from Journal of Dairy Science
#19
of 43 outputs
Altmetric has tracked 12,418,082 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,220 research outputs from this source. They receive a mean Attention Score of 3.2. This one is in the 46th percentile – i.e., 46% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 147,464 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
