Characterization of a bacteriocin-like substance produced by a vaginal Lactobacillus salivarius strain.

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

Characterization of antimicrobial substance from Lactobacillus salivarius KL-D4 and its application as biopreservative for creamy filling

Lactobacillus salivarius KL-D4 isolated from duck intestine produced bacteriocin which was stable at high temperature and a wide pH range of 3-10. Its cell free supernatant at pH 5.5 exhibited wide inhibitory spectrum against both G+ and G- bacteria. The highest bacteriocin production was obtained in MRS broth supplemented with 0.5 % (w/v) CaCO3 at 6 h by gentle shaking. PCR walking using speci...

Subspecies diversity in bacteriocin production by intestinal Lactobacillus salivarius strains.

A recent comparative genomic hybridization study in our laboratory revealed considerable plasticity within the bacteriocin locus of gastrointestinal strains of Lactobacillus salivarius. Most notably, these analyses led to the identification of two novel unmodified bacteriocins, salivaricin L and salivaricin T, produced by the neonatal isolate L. salivarius DPC6488 with immunity, regulatory and ...

Effect of Bacteriocin Produced by Lactobacillus casei with Probiotic Potential Isolated from Milk on the Ability of Biofilm Production by Streptococcus salivarius Obtained from Dental Plaque

Background and purpose: Dental plaque is a biofilm that is formed on the surface of the tooth. Carious lesions are caused by inappropriate ecological changes in microbial flora of the plaque biofilm. In this study, the effect of Lactobacillus casei bacteriocin, isolated from dairy products, was investigated on Streptococcus salivarius biofilm formation. Materials and methods: In this experimen...
