Abstract:
... With the increase of antimicrobial resistances due to the widespread use of antibiotics, the search of new probiotics to control aquaculture diseases has a growing public interest. The aim of this study was to isolate bacteria with antimicrobial effect from the gut of marine healthy fishes and select lactic acid bacteria (LAB) as potential probiotics, being strains considered as generally regarded ...

Enterococcus; GRAS substances; Lactobacillus; Lactococcus; Pediococcus; antimicrobial peptides; food biopreservation; lactic acid bacteria; meat; mechanism of action; milk; nisin
Abstract:
... Bacteriocins are ribosomal-synthesized antimicrobial peptides that inhibit the growing of pathogenic and/or deteriorating bacteria. The most studied bacteriocin-producing microorganisms are lactic acid bacteria (LAB), as they have great potential application in food biopreservation, since the majority have GRAS (Generally Recognized as Safe) status. The LAB-producing bacteriocins and/or bacterioci ...

Abstract:
... Aromatic plants comprise many biologically active compounds such as mainly anti-microbial, anti-oxidant, anti-parasitic, anti-fungal and anti-inflammatory characteristics. The demand for these plants and their derivatives has became popular since they are natural and generally recognized as safe products. Thus, chemical composition of volatile oils, obtained from Myrtus communis (Myrtle), Citrus s ...

Abstract:
... Twenty three enterococci were isolated from Lighvan cheese. Enterococcal isolates identified by 16S rDNA sequencing, were evaluated for their safety and also examined for antibacterial activity and presence of the genes coding for enterocins. Four enterococcal isolates exhibited inhibitory activity against Listeria innocua and E. faecalis and harbored the bacteriocin genes (enterocins A, B, P, X a ...

Abstract:
... Enterococci, no more regarded as GRAS (Generally Recognized As Safe) organism, are emerging as an important source of nosocomial infections worldwide. The main contributors in pathogenesis of enterococci are the presence of various virulent factors and antibiotic resistance genes. We aimed to examine the prevalence, dissemination, antibiotic resistance and virulent factors associated with enteroco ...

Abstract:
... Direct-fed microbials (DFM) have been employed in ruminant production for over 30 yr. Originally, DFM were used primarily in young ruminants to accelerate establishment of the intestinal microflora involved in feed digestion and to promote gut health. Further advancements led to more sophisticated mixtures of DFM that are targeted at improving fiber digestion and preventing ruminal acidosis in mat ...

Abstract:
... The long history of safety has contributed to the acceptance of probiotics as a safe food adjunct. Consequently, many probiotic products and their applications have been granted GRAS (generally regarded as safe) status. However, this classification has been frequently generalized for all probiotic strains regardless of their application. Cases of probiotics from the genera Lactobacillus, Leuconost ...

Abstract:
... Unlike most of lactic acid bacteria, the Enterococcus genus is not considered “generally recognized as safe” (GRAS). Safety assessment for enterococci remains controversial. While enterococci are considered “positive" or useful in cheese technology, isolates of this genus have emerged as opportunistic pathogens for humans. Thus these bacteria have the paradoxical position of being useful in dairy ...
