Background and Aim: Probiotics are beneficial microorganisms for humans animals. In this study, we developed a microencapsulated probiotic with antibacterial activity against avian pathogenic Escherichia coli (APEC). Materials Methods: Alignment of the 16S rRNA sequences isolate WU222001 those deposited in GenBank revealed that was Pediococcus acidilactici 99.6% homology. This bacterium charact...

Pediococci are homofermentative, gram-positive, nonmotile, catalase-negative facultative anaerobes of the family Streptococcaceae and are used in the biotechnology and food industries (1, 2, 7). The ecologic niche of pediococci in humans appears to be the enteral tract (7). Although pediococci have been described as harmless bacteria (5), they have been infrequently recovered from the human res...

A realistic description of the variability in bacterial growth and division is critical to produce reliable predictions of safety risks along the food chain. Individual-based modeling of bacteria provides the theoretical framework to deal with this variability, but it requires information about the individual behavior of bacteria inside populations. In this work, we overcome this problem by est...

Five bacteriocin-producing lactic acid bacteria (LAB):Enterococcus faecium ET05, Lactobacillus curvatus ET06, L. curvatus ET30, L. deldrueckii T32 and Pediococcus acidilactici ET34, selected by their capacity for growth and producing inhibition in vitro at high salt-on-water content, low emperature and anaerobic atmosphere, conditions simulating cold-smoked fish, were inoculated onto salmon fil...

during the recent years, there has been an increasing interest toward dietary administration of synbiotic to improve growth, immunity and physiology of fish. the aim of this study was to evaluate the effects of feeding on synbiotic (pediococcus acidilactici and fructooligosaccharide) enriched adult artemia franciscana on growth indices, intestinal microbiota and stress resistance of angel fish ...

The pediococci residing on plants resemble the lactobacilli, but they differ from the streptococci in their limited distribution and low population level on plants. They are a subgroup within the genus Pediococcus which grow freely in neutral media and require neither NaCl nor CO(2). They are most readily recognized by the ability to initiate growth in liquid media, acidified to pH 5.0, which c...

The class II bacteriocins pediocin PA-1, from Pediococcus acidilactici, and lactococcin A, from Lactococcus lactis subsp. lactis bv. diacetylactis WM4 have a number of features in common. They are produced as precursor peptides containing similar amino-terminal leader sequences with a conserved processing site (Gly-Gly at positions -1 and -2). Translocation of both bacteriocins occurs via a ded...
