Infective cycle of dairy bacteriophages
(Nova Science Publishers, 2012)
Phages follow two strategies to survive: they can either infect and lyse the host cell (virulent/lytic phages) or insert its genome into the host chromosome (prophages). In either case, the first step is the adsorption of ...
Leuconostoc mesenteroides and Leuconostoc pseudomesenteroides bacteriophages: Genomics and cross-species host ranges
(Elsevier Science, 2017-09)
Unveiling virus-host interactions are relevant for understanding the biology and evolution of microbes globally, but in particular, it has also a paramount impact on the manufacture of fermented dairy products. In this ...
Characterization of two virulent phages of Lactobacillus plantarum
(American Society for Microbiology, 2012-12)
We characterized two Lactobacillus plantarum virulent siphophages, ATCC 8014-B1 (B1) and ATCC 8014-B2 (B2), previously isolated from corn silage and anaerobic sewage sludge, respectively. Phage B2 infected two of the eight ...
Technological performance of spontaneous phage-resistant derivatives of Leuconostoc mesenteroides and Leuconostoc pseudomesenteroides during milk fermentation
(Elsevier, 2018-03)
A total of 142 presumptive phage-resistant derivatives were isolated from six commercial phage-sensitive Leuconostoc mesenteroides and Leuconostoc pseudomesenteroides strains, using six phages either individually or in ...
Characterization of a New Virulent Phage (MLC-A) of Lactobacillus paracasei
(American Dairy Science Association, 2006-12)
A new virulent bacteriophage (MLC-A) was recently isolated in Argentina from a probiotic dairy product containing a strain of Lactobacillus paracasei. Observation of the lysate with an electron microscope revealed bacteriophage ...
Characterization of spontaneous phage-resistant derivatives of Lactobacillus delbrueckii commercial strains
(Elsevier Science, 2006-12)
A total of 44 spontaneous phage-resistant mutants were isolated from three commercial Lactobacillus delbrueckii strains by secondary culture and agar plate methods. Phenotypic characteristics related to their phage-resistance ...
Lysogeny in Lactobacillus delbrueckii strains and characterization of two new temperate prolate-headed bacteriophages
(Wiley Blackwell Publishing, Inc, 2008-11)
Aims: Frequency of lysogeny in Lactobacillus delbrueckii strains (from commercial and natural starters) and preliminary characterization of temperate bacteriophages isolated from them. Methods and Results: Induction of ...
Phage-resistance linked to cell heterogeneity in the commercial strain Lactobacillus delbrueckii subsp. lactis Ab1
(Elsevier Science, 2008-12)
The aim of this work was to study the relationship between the cell morphological heterogeneity and the phage-resistance in the commercial strain Lactobacillus delbrueckii subsp. lactis Ab1. Two morphological variants ...
