In vivo bioluminescence imaging of the spatial and temporal colonization of lactobacillus plantarum 423 and enterococcus mundtii ST4SA in the intestinal tract of mice
(BMC (part of Springer Nature), 2018-10-30)
Background: Lactic acid bacteria (LAB) are major inhabitants and part of the normal microflora of the gastrointestinal tract (GIT) of humans and animals. Despite substantial evidence supporting the beneficial properties ...
Evaluation of a nisin-eluting nanofiber scaffold to treat Staphylococcus aureus-induced skin infections in mice
(American Society for Microbiology, 2013-08)
Staphylococcus aureus is a virulent pathogen and a major causative agent of superficial and invasive skin and soft tissue infections (SSSTIs). Antibiotic resistance in S. aureus, among other bacterial pathogens, has rapidly ...
Lactobacillus equigenerosi strain Le1 invades equine epithelial cells
(American Society for Microbiology, 2012)
Lactobacillus equigenerosi strain Le1, a natural inhabitant of the equine gastrointestinal tract, survived pH 3.0 and incubation in the presence of 1.5% (wt/vol) bile salts for at least 2 h. Strain Le1 showed 8% cell surface ...
Copper-containing anti-biofilm nanofiber scaffolds as a wound dressing material
(Public Library of Science, 2016)
Copper particles were incorporated into nanofibers during the electrospinning of poly-D,L-lactide (PDLLA) and poly(ethylene oxide) (PEO). The ability of the nanofibers to prevent Pseudomonas aeruginosa PA01 and Staphylococcus ...
Migration of bacteriocins across gastrointestinal epithelial and vascular endothelial cells, as determined using in vitro simulations
(Nature Research (part of Springer Nature), 2019-08-07)
Little is known about the migration of bacteriocins across human cells. In this study, we report on migration of three bacteriocins nisin, plantaricin 423 and bacST4SA across colonic adenocarcinoma (Caco-2) cells and human ...
Heterologous expression of the class IIa bacteriocins, plantaricin 423 and mundticin ST4SA, in escherichia coli using green fluorescent protein as a fusion partner
(Frontiers Media, 2020)
The antilisterial class IIa bacteriocins, plantaricin 423 and mundticin ST4SA, have previously been purified from the cell-free supernatants of Lactobacillus plantarum 423 and Enterococcus mundtii ST4SA, respectively. Here, ...
Lactic acid bacteria : taxonomy antimicrobial characteristics and probiotics
(Stellenbosch : Stellenbosch University, 2002)
Inaugural address delivered by Prof Leon Milner Theodore Dicks during 2002, Stellenbosch University.
Characterization of Leucocin B-KM432Bz from Leuconostoc pseudomesenteroides isolated from Boza, and comparison of its efficiency to Pediocin PA-1
A bacteriocin-producing bacterium was isolated from boza and identified as Leuconostoc pseudomesenteroides KM432Bz. The antimicrobial peptide was purified and shown to be identical to other class IIa bacteriocins: leucocin ...
Antimikrobiese nanovesels vir waterbehandeling : poli(vinielalkohol)- en poli(akrielonitriel)- nanovesels met silwer-nanopartikels
Daar moet verbeter word op bestaande watersuiweringsmetodes ten einde mikrobiologies veilige en bekostigbare drinkwater te verskaf. Nanovesels word reeds gebruik in waterfiltrasiesisteme en nanofiltrasie mag selfs as ’n ...
Release of bacteriocins from nanofibers prepared with combinations of poly(D,L-lactide) (PDLLA) and poly(ethylene oxide) (PEO)
Plantaricin 423, produced by Lactobacillus plantarum, and bacteriocin ST4SA produced by Enterococcus mundtii, were electrospun into nanofibers prepared from different combinations of poly(D,L-lactide) (PDLLA) and poly(ethylene ...
