The objective of this study was to isolate multifunctional bacteriocin-producing strains; characterize the expressed bacteriocin for control Listeria monocytogenes and vancomycin-resistant Enterococcus; evaluate safety studied explore their antifungal activity.Two Pediococcus strains were isolated from silage samples obtained an organic farm in Belogradchik, Bulgaria. identified by 16S rRNA sequencing analysis characterized as bacteriocins producers. Strong antimicrobial activity detected...
Three out of one hundred eighty putative LAB isolates from Korean traditional fermented soybean paste were identified to be unique and bacteriocinogenic strains. Based on phenotypic 16S rRNA sequencing analysis, selected strains as Enterococcus faecium ST651ea, E. ST7119ea ST7319ea. The properties the studied evaluated against Listeria monocytogenes ATCC15313, innocua ATCC33090 vancomycin-resistant VRE19 clinical origin. ST7319ea expressed bacteriocins with an activity 12,800 AU/mL, 25,600...
Antibiotics have been one of the most important discoveries in area applied medical microbiology; however, as a result various factors, we are currently facing dramatic and relatively dangerous increase number cases antibiotic resistance, need for new types antimicrobials continues to grow. New approaches needed combat antibiotic-resistant pathogens. Bacteriocins, part group antimicrobial peptides, can be considered alternatives and/or complements known antibiotics. Their narrow spectra...
The bacteriocin-producing strain Enterococcus faecium ST10Bz, isolated from boza, a Bulgarian cereal-based beverage, exhibited strong activity against Listeria strains, vancomycin-resistant and other but not most of the lactic acid bacteria (LAB) strains included in test panel. Bacteriocin ST10Bz was proven as stable antimicrobial, even after exposure to various environmental conditions, including varying pH values, temperatures, commonly used chemicals industry laboratory practice. L....
Aims The objective of this study was to isolate a bacteriocin-producing strain and characterize the expressed bacteriocin for control Listeria monocytogenes with aim biopreservation application. Methods Results Soil samples from Korean organic farm were subjected microbiological analysis isolation potential bacteriocinogenic LAB, based on three-level approach, using L. ATCC 15313 as an indicator test micro-organism. From total 17 isolates inhibitory potential, seven confirmed be producers....
Preservation of probiotics by lyophilization is considered a method choice for developing stable products. However, both direct consumption and reconstitution dehydrated probiotic preparations before application “compromise” the survival functional characteristics microorganisms under stress upper gastro-intestinal tract. We evaluated impact different food additives on viability, mucin adhesion, zeta potential freeze-dried putative probiotic, Lactiplantibacillus (Lp.) plantarum HAC03....
Bacillus velezensis ST03 and ST32, amyloliquefaciens ST06 ST109, subtilis ST08 were isolated from artisanal-produced kimchi identified based on 16S rRNA partial sequencing. DNA obtained the investigated bacilli generated positive results for lichenicidin, iturin, subtilosin, surfactin a strain-specific basis. The strains found to produce antimicrobial metabolites with activity levels ranging between 800 1600 AU/mL basis, as determined against Listeria monocytogenes ATCC15313. Moreover, all...
Two Bacillus spp. isolated from kimchi, tequilensis ST816CD and subtilis ST830CD, were characterized for their antimicrobial properties safety. The proteinaceous nature of inhibitory metabolites was confirmed after exposure to proteolytic enzymes, resulting in partial loss the effect. This indicated that different non-proteinaceous substances may also be produced by these strains. hypothesis later when genes associated with production surfactants detected DNA. expressed not affected...
In this study, we have evaluated the effects of previously characterized bacteriocins produced by E. faecium strains ST651ea, ST7119ea, and ST7319ea, against biofilm formation biofilms formed L. monocytogenes ATCC15313 vancomycin-resistant VRE19. The on ATCC151313 were crystal violet assay further confirmed quantifying viable cells cell metabolic activities through flow cytometry TTC assay, respectively, indicating that bacteriocin required to completely eradicate are at least 1600 AU mL−1,...
The control of Listeria monocytogenes is a relevant goal for dairy products, process that begins from the supply feed and management animals' health. In present study, we evaluated safety two bacteriocinogenic Pediococcus strains show both can be considered as safe, based on their haemolytic activity, biogenic amine production antibiotic resistance, all through phenotypical biomolecular approaches. Both have shown potential producer γ-aminobutiric acid (GABA) carry an incomplete set genes...
Multidrug resistance in foodborne and clinical pathogens is a worldwide health problem. The urgent need for new alternatives to the existing antibiotics emerging. Bacteriocin-like inhibitory substances can be considered part of generation antimicrobials, which potentially applied food industry care practices. This study aimed select
Abstract The gastrointestinal tract (GIT) harbors the largest group of microbiotas among microbial communities human host. resident organisms typical a healthy gut are well adapted to environment while alteration these populations can trigger disorders that may affect health and well‐being Various investigations have applied different tools study bacterial in their correlation with such as inflammatory bowel disease (IBD), obesity, diabetes. This proposes fluorescent situ hybridization,...
