Catabolism of serine by Pediococcus acidilactici and Pediococcus pentosaceus.
The ability to produce diacetyl from pyruvate and l-serine was studied in various strains of Pediococcus pentosaceus and Pediococcus acidilactici isolated from cheese. After being incubated on both substrates, only P. pentosaceus produced significant amounts of diacetyl. This property correlated with measurable serine dehydratase activity in cell extracts. A gene encoding the serine dehydratase...
متن کاملSepticemia caused by vancomycin-resistant Pediococcus acidilactici.
A case of septicemia caused by vancomycin-resistant Pediococcus acidilactici is discussed. This appears to be the first reported case of septicemia caused by this organism. The characteristics and antimicrobial susceptibilities of this organism are described.
متن کاملRecombinant laccase from Pediococcus acidilactici CECT 5930 with ability to degrade tyramine
Biogenic amines degradation by bacterial laccases is little known, so we have cloned and heterologously expressed, in E. coli, a new laccase from Pediococcus acidilactici CECT 5930 (Lpa5930), a lactic acid bacterium commonly found in foods able to degrade tyramine. The recombinant enzyme has been characterized by physical and biochemical assays. Here we report the optimization of expression and...
متن کاملLactose-fermenting Salmonella.
Salmonella species are generally considered to be unable to ferment lactose and sucrose according to Bergey's Manual. Recently, however, J. M. Bulmash, McD. Fulton, and J. Jiron (J. Bacteriol. 89:259, 1965) and L. J. Kunz and W. H. Ewing (J. Bacteriol. 89:1629, 1965) have reported two separate species of Salmonella capable of fermenting lactose and sucrose. The organism reported here again illu...
متن کاملUse of a bacteriocin produced by Pediococcus acidilactici to inhibit Listeria monocytogenes associated with fresh meat.
A bacteriocin produced by Pediococcus acidilactici had an inhibitory and bactericidal effect on Listeria monocytogenes associated with fresh meat. MICs were significantly lower than minimum killing concentrations. When meat was inoculated with L. monocytogenes, the bacteriocin reduced the number of attached bacteria in 2 min by 0.5 to 2.2 log cycles depending upon bacteriocin concentration. Mea...
