Background: Bacteriocins are small peptides which are ribosomally synthesized and have been shown to have wide range of antimicrobial activity. The aim of this study was to optimize the production of L. paracasei MG847589 bacteriocin. Furthermore, the potential antibacterial properties of the novel bacteriocins were characterized and evaluated against Staphylococcus aureus. Methods: The presen...

Bacteriocins are proteinaceous antibacterial compounds that exhibit bactericidal activity against species closely related to the producer strain. The aim of this research was to investigate the production of bacteriocin by Bacillus spp. isolated from intestinal bacterial flora of the Caspian Frisian Roach (Rutilus frisii kutum). A bacteriocin produced by the bacterium Bacillus cereus strain RF ...

Background: Weissellicin 110 is the only bacteriocin reported in Weissella cibaria up to now. This bacteriocin represents several unique features. This is the first report on the gene sequence that encodes for the bacteriocin. Objectives: Providing a rapid detection method to isolate the weissellicin 110 encoding gene and determination of the bacteriocin distribution were the objectives. Materi...

Background: Staphylococcus aureus is a major food-borne pathogen worldwide and a frequent contaminant of fruit juices. This study aimed to evaluate the antibacterial activity of bacteriocin-containing Cell-Free Culture Supernatants (CFCS) of Pediococcus pentosaceus IO1 against S. aureus inoculated in fruit juices, as well as their impact on the juice sensory attributes. Methods: The orange and...

Rhizobium strains nodulating green gram [Vigna radiata (L.) Wilczek] were found to produce bacteriocin on modified Bergersen's medium and inhibited the growth of homologous Rhizobium strains. Four bacteriocin producing and four bacteriocin non-producing strains were compared for their effect on nodulation, in planta nitrogenase activity and plant dry weight of green gram. The bacteriocin produc...

Background and Objective: Lactobacilli are known for their probiotic activities and potential to combat pathogens. This study aimed to investigate the antimicrobial activity of Lactobacillus strains isolated from various sources against pathogenic bacteria, with the objective of identifying potential bacteriocin producers. Methods: A total of 140 samples were collected from different sources. ...

─Among antimicrobial materials produced by Pediococcus pentosaceus, bacteriocin have gained the greatest interest in food preservation as a natural substance. A bacteriocin producing P. pentosaceus was isolated from vegetables and human stool in a previous study. Purification, activity measurement, and characteristics of the bacteriocin was also determined. The yield of the bacteriocin was 9.08...

Bacteriocin production is a spiteful behavior of bacteria that is central to the competitive dynamics of many human pathogens. Social evolution predicts that bacteriocin production is favored when bacteriocin-producing cells are mixed at intermediate frequency with their competitors and when competitive neighborhoods are localized. Both predictions are supported by biofilm experiments. However,...

Twenty-two bacteriocin-producing Enterococcus isolates obtained from food and animal sources, and demonstrating activity against Listeria monocytogenes, were screened for bacteriocin-related genes using a bacteriocin PCR array based on known enterococcal bacteriocin gene sequences in the NCBI GenBank database. The 22 bacteriocin-positive (Bac+) enterococci included En. durans (1), En. faecalis ...
