Characterisation and selection of probiotic lactobacilli for a preliminary minipig feeding trial and their effect on serum cholesterol levels, faeces pH and faeces moisture content.
A lowering effect on serum cholesterol levels was indicated after three weeks probiotic feeding, concomitant with an increase in the moisture content of the faeces and Lactobacillus cell numbers, while triglycerides, pH and number of lactic acid bacteria in faece were not significantly influenced by probiotic supplementation.

Evaluation of Enterococcus mundtii ST4SA and Lactobacillus plantarum 423 as probiotics by using a gastro-intestinal model with infant milk formulations as substrate.
Survival of strains ST4SA and 423 improved when used as combined cultures in the GIM and compared well with the survival of commercially available probiotics subjected to the same conditions. Expand
Proposal to reclassify Leuconostoc oenos as Oenococcus oeni [corrig.] gen. nov., comb. nov..
Phylogenetic studies, in particular 16S and 23S rRNA sequencing studies, have revealed that L. oenos represents a distinct subline that is separate from other Leuconostoc spp. Expand
Lactobacillus plantarum isolated from molasses produces bacteriocins active against Gram-negative bacteria
Abstract Two bacteriocins, ST28MS and ST26MS, produced by Lactobacillus plantarum isolated from molasses, inhibited the growth of Lactobacillus casei, Lactobacillus sakei, Staphylococcus aureus,Expand
Isolation and characterization of fructophilic lactic acid bacteria from fructose-rich niches.
Fourteen strains of fructophilic lactic acid bacteria were isolated from fructose-rich niches, flowers, and fruits and were divided into two groups, one of which contained three unidentified strains of Lactobacillus that grew well on D-fructose and onD-glucose with the electron acceptors, but at a delayed rate.

Effect of Growth Medium on Bacteriocin Production by Lactobacillus plantarum ST194BZ, a Strain Isolated from Boza**
No plasmids were recorded for strain ST194BZ, suggesting that the genes encoding bacteriocin production are located on the genome, and this strain inhibits the growth of Lactobacillus casei, LactOBacillus sakei and Pseudomonas aeruginosa. Expand
Characterization of bacteriocin ST8KF produced by a kefir isolate Lactobacillus plantarum ST8KF
The results suggest that bacST8KF may be a secondary metabolite and shows that its mode of activity is bacteriostatic, and it is shown that it is sensitive to proteolytic enzymes and heat resistant. Expand
Characterization of two bacteriocins produced by Pediococcus acidilactici isolated from "Alheira", a fermented sausage traditionally produced in Portugal.
Two isolates (HA-6111-2 and HA-5692-3) from different sausages were identified as strains of Pediococcus acidilactici, which are sensitive to treatment with Triton X-114 and Trit on X-100, but resistant to Tween 20, Tween 80, SDS, Oxbile, NaCl, urea and EDTA. Expand
Screening for bacteriocin-producing lactic acid bacteria from boza, a traditional cereal beverage from Bulgaria: Comparison of the bacteriocins
Bacteria isolated from boza produced bacteriocins active against Lactobacillus casei, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis, suggesting that the genes encoding the bacteriOCins are located on the genomes. Expand
Pediocin ST18, an anti-listerial bacteriocin produced by Pediococcus pentosaceus ST18 isolated from boza, a traditional cereal beverage from Bulgaria
Lactic acid bacteria isolated from boza, a cereal-fermented beverage from Belogratchik, Bulgaria, were screened for the production of bacteriocins and one of the strains produced pediocin ST18, which had bacteriostatic action towards L. innocua, with no cell lyses. Expand
