Extreme thermal resistance of phages isolated from dairy samples: updating traditional phage detection methodologies
(Elsevier, 2013-06)
Starter culture failures due to bacteriophage attacks reduce product quality and may cause financial losses. It was the aim of this work to revise and update the Standard IDF microbiological methodology for phage detection ...
Virulence of Leuconostoc phages: Influence of stress conditions associated to dairy processes on their host-phage interactions
(Elsevier Science, 2019-05)
In this work, we assessed the impact of technological cell stress conditions, commonly present in industrial dairyprocesses, on the host strain-phage interactions in Leuconostoc. Adsorption and burst size of LDG ...
Bacteriophages on dairy foods
(Wiley Blackwell Publishing, Inc, 2019-01)
This review focuses on the impact of bacteriophages on the manufacture of dairy foods. Firstly, the impact of phages of lactic acid bacteria in the dairy industry, where they are considered enemies, is discussed. The sources ...
Review: Efficiency of physical and chemical treatments on the inactivation of dairy bacteriophages
(Frontiers Research Foundation, 2012-01)
Bacteriophages can cause great economic losses due to fermentation failure in dairy plants. Hence, physical and chemical treatments of raw material and/or equipment are mandatory to maintain phage levels as low as possible. ...
Diversity among Lactobacillus paracasei phages isolated from a probiotic dairy product plant
(Wiley Blackwell Publishing, Inc, 2009)
Aims: To evaluate the phage diversity in the environment of a dairy industry which manufactures a product fermented with a probiotic strain of Lactobacillus paracasei.Methods and results: Twenty-two Lact. paracasei phages ...
Adsorption of temperate phages of Lactobacillus delbrueckii strains and phage resistance linked to their cell diversity
(Wiley Blackwell Publishing, Inc, 2011-04)
Aims: The aim of this work was to study the adsorption step of two new temperate bacteriophages (Cb1/204 and Cb1/342) of Lactobacillus delbrueckii and to isolate phage-resistant derivatives with interesting technological ...
Streptococcus thermophilus Phages in Whey Derivatives: From Problem to Application in the Dairy Industry
(MDPI AG, 2022-04)
Fifteen samples of whey protein concentrate (WPC) were tested against 37 commercial Streptococcus thermophilus strains to detect infective bacteriophages. Seventy-three diverse phages were isolated from 12 samples, ...
Diversity of Streptococcus thermophilus Phages in a Large-Production Cheese Factory in Argentina
(American Dairy Science Association, 2006-12)
Phage infections still represent a serious risk to the dairy industry, in which Streptococcus thermophilus is used in starter cultures for the manufacture of yogurt and cheese. The goal of the present study was to analyze ...
Biocides for dairy bacteriophage inactivation
(Nova Science Publishers, 2012)
One of the main problems encountered in dairy fermentations is phage infection, which can alter the quality of fermented products or delay manufacturing processes. Several control strategies, such as sanitizers, thermal ...
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 ...
