PCR method for detection and identification of Lactobacillus casei/paracasei bacteriophages in dairy products
(Elsevier Science, 2008-05)
Bacteriophage infections of starter lactic acid bacteria (LAB) pose a serious risk to the dairy industry. Nowadays, the expanding use of valuable Lactobacillus strains as probiotic starters determines an increase in the ...
Lactobacillus casei/paracasei: aislamiento de mutantes espontáneos fagorresistentes para uso industrial
(Centro de Publicaciones Universidad Nacional del Litoral, 2010-01)
ResumenLos fagos de bacterias probióticas son causa de enormes pérdidas económicas y severas limitaciones a las estrategias de control. En este trabajo se aislaron y caracterizaron mutantes de L. casei/paracasei empleando ...
Bacteriófagos de Lactobacillus casei/paracasei. Caracterización y estudio de la fagorresistencia
(2007-03-23)
Las infecciones fágicas a bacterias probióticas, particularmente Lactobacillus casei/paracasei, son económica y tecnológicamente más severas que sobre bacterias acidolácticas. Su estudio se ha incrementado por la diversificación ...
Technological and probiotic characterisation of Lactobacillus casei / paracasei strains and their phage resistant mutants
(Elsevier, 2014)
Technological, biological and functional attributes of two groups of spontaneous bacteriophage-resistant mutants were investigated to verify features similar to those of their respective phage-sensitive parent probiotic ...
Characterization of receptor sites for bacteriophages PL-1, J-1 and MLC-A using two strains of Lactobacillus casei
(Nova Science Publishers, 2009)
Receptor sites and adsorption process of two collection phages and the first Argentinian indigenous Lactobacillus paracasei bacteriophage (MLC-A), on purified cell walls were characterized. To identify the nature of ...
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 ...
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 ...
Genomic diversity of phages infecting probiotic strains of Lactobacillus paracasei
(American Society for Microbiology, 2015-10)
Strains of the Lactobacillus casei group have been extensively studied because some are used as probiotics in foods. Conversely, their phages have received much less attention. We analyzed the complete genome sequences of ...
Thermal and chemical resistance of Lactobacillus casei and Lactobacillus paracasei bacteriophages
(Wiley Blackwell Publishing, Inc, 2004-06)
Aims: The survival of two collection Lactobacillus casei and L. paracasei bacteriophages when subjected to thermal and chemical treatments was investigated. Methods and Results: Thermal resistance was evaluated by heating ...
