ABSTRACT We studied the potential inhibitory effect of Lactobacillus casei strain Shirota (from fermented milk product Yakult [Yakult Ltd., Tokyo, Japan]) on Helicobacter pylori by using (i) in vitro inhibition assays with H. SS1 (Sydney 1) and nine clinical isolates (ii) vivo mouse model infection over a period 9 months. In activity against all was observed presence viable L. cells but not cell-free culture supernatant, although there profound urease activity. experiments were performed...
Lactic acid bacteria (LAB) were isolated from Greek traditional wheat sourdoughs manufactured without the addition of baker's yeast. Application sodium dodecyl sulfate-polyacrylamide gel electrophoresis total cell protein, randomly amplified polymorphic DNA-PCR, DNA-DNA hybridization, and 16S ribosomal DNA sequence analysis, in combination with physiological traits such as fructose fermentation mannitol production, allowed us to classify into species Lactobacillus sanfranciscensis, brevis,...
ABSTRACT The population dynamics of pseudomonads in gilt-head sea bream Mediterranean fish ( Sparus aurata ) stored under different conditions were studied. Phenotypic analysis and sodium dodecyl sulfate-polyacrylamide gel electrophoresis whole-cell proteins performed to identify a total 106 Pseudomonas strains isolated from S. temperatures (at 0, 10, 20°C) packaging (air modified atmosphere 40% CO 2 -30% N O ). lundensis was the predominant species, followed by fluorescens , while fragi...
Kefir is a high nutritional fermented dairy beverage associated with wide range of health benefits. It constitutes unique symbiotic association, comprising mainly lactic acid bacteria, yeasts, and occasionally acetic which strongly influenced by the geographical origin grains, type milk used, manufacture technology applied. Until recently, kefir microbiota has been almost exclusively studied culture-dependent techniques. However, high-throughput sequencing, alongside omics approaches,...
Taxonomic studies were performed on some Streptococcus-like organisms isolated from naturally fermented Greek Kasseri cheese. By SDS-PAGE analysis of whole-cell proteins the group was found to be quite different Streptococcus thermophilus. Comparative 16S and 23S rRNA sequence analyses showed that isolates represent a new species within genus Streptococcus, where they are most closely related bovis cluster. On basis these phylogenetic results phenotypic differences, species, macedonicus, is...
Streptococcus macedonicus ACA-DC 198, a strain isolated from Greek Kasseri cheese, produces food-grade lantibiotic named macedocin. Macedocin has molecular mass of 2,794.76 +/- 0.42 Da, as determined by electrospray spectrometry. Partial N-terminal sequence analysis revealed 22 amino acid residues that correspond with the lantibiotics SA-FF22 and SA-M49, both which were pathogen pyogenes. inhibits broad spectrum lactic bacteria, well several food spoilage pathogenic including Clostridium...
