Application of antimicrobials for the elimination of Escherichia coli and Listeria monocytogenes in brine injected beefDownload
The application of antimicrobials to a brine-injected raw beef roast for the elimination/inhibition of heat resistant Escherichia coli and Listeria monocytogenes was investigated. The choice of antimicrobials for use in brine injected beef was based on minimum bactericidal concentration in brine...
Although nanocrystalline silver is used commercially to treat burns and wounds, the mechanisms of action (MOA) for its activity are not clear. The purposes of this work were to determine if nanocrystalline silver has anti-inflammatory activity, determine physicochemical properties critical for...
Mussels can obtain strong underwater attachment to virtually all kinds of surfaces including rocks, metals, wood structures, polymers and concretes by secreting mussel foot proteins to form byssus. Great efforts have been dedicated to understanding this behavior and it is found that an catecholic...
Paenibacillus polymyxa NRRL B-30509, Paenibacillus terrae NRRL B-30644 and P. polymyxa NRRL B-30507 were found to produce several bacteriocins and non-ribosomal peptides. All three strains produce tridecaptins, non-ribosomal lipopeptides antimicrobially active against food pathogen Campylobacter...
The lipopeptides, tridecaptin A1, tridecaptin B1 and cerexin A1 were isolated from Paenibacillus terrae NRRL B-30644, Paenibacillus polymyxa NRRL B-30507 and Bacillus mycoides ATCC 21929, respectively. A combination of chemical synthesis, peptide derivatization, high performance liquid...
Acidocin B (AcdB), a bacteriocin from Lactobacillus acidophilus M46 that was initially reported to be a linear peptide, was purified and shown to be circular based on MALDI-TOF MS and MS/MS sequencing. MS analysis further revealed that AcdB is comprised of 58 amino acid residues, instead of 59...
Lantibiotics (lanthionine containing antibiotics) are highly post-translationally modified peptides used by bacteria as a form of chemical warfare. In light of the challenges faced today in the field of antibacterial therapy, these potent natural products are useful lead compounds for the...
“Blown-pack” spoilage of beef by psychrotrophic Clostridium spp. occurs sporadically and resistance of the endospores to most interventions makes them very difficult to control. Current interventions used to control spoilage and pathogenic bacteria, such as acid washes and heat treatments, do...
