Antifungal Effect of Phenyllactic Acid Produced by Lactobacillus casei Isolated from Button Mushroom

Utilization of phenylalanine, phenyllactic acid, and phenylpyruvic acid by Lactobacillus casei.

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...

Antifungal activity of phenyllactic acid against molds isolated from bakery products.

Phenyllactic acid (PLA) has recently been found in cultures of Lactobacillus plantarum that show antifungal activity in sourdough breads. The fungicidal activity of PLA and growth inhibition by PLA were evaluated by using a microdilution test and 23 fungal strains belonging to 14 species of Aspergillus, Penicillium, and Fusarium that were isolated from bakery products, flours, or cereals. Less ...

Antibacterial Activity of Lactobacillus plantarum and Lactobacillus casei on Burkholderia cepacia Isolated from Imam Ali Hospital

Background: Nosocomial infections are the causes of the most common of morbidity and mortality, prolonged hospital stay, and increased hospital costs worldwide. Today probiotic bacteria, as antibacterial agents, attracted the attention of clinicians. The current study aimed at determining the antibacterial activity of Lactobacillus plantarum and L. casei species against Burkholderia cepacia iso...

Proteolysis by Lactobacillus casei

A study of the proteinase activity of Lactobacillus casei grown in milk and of cell-free extract of L. cawi has been reported on in a previous paper (Brandsaeter and Nelson, 1956). Whereas the proteinases of L. casei have been studied to some extent earlier, very little has been done to characterize the peptidases of this organism. Other lactobacilli hydrolyze some peptides (Christophersen and ...
