Characterization of a bacteriocin-like substance produced by Bacillus amyloliquefaciens isolated from the Brazilian Atlantic forest.

Characterization of Bacteriocin like inhibitory substance produced by a new Strain Brevibacillus borstelensis AG1 Isolated from ‘Marcha’

In the present study, a bacterium isolated from Marcha- a herbal cake used as traditional starter culture to ferment local wine in North East India, was evaluated for bacteriocin like inhibitory substance production and was tested against six food borne/spoilage causing pathogens viz. Listeria monocytogenes MTCC 839, Bacillus subtilis MTCC 121, Clostridium perfringens MTCC 450, Staphylococcus a...

Isolation of the Bacillus subtilis antimicrobial peptide subtilosin from the dairy product-derived Bacillus amyloliquefaciens.

AIMS To purify and characterize an antimicrobial protein (bacteriocin) isolated from the dairy product-derived Bacillus amyloliquefaciens. METHODS AND RESULTS An unknown bacterial species cultured from the Yogu Farm probiotic dairy beverage was identified through 16S ribosomal RNA analysis as B. amyloliquefaciens, a phylogenetically close relative of Bacillus subtilis. The cell-free supernata...

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

Detection and Characterization of Weissellicin 110, a Bacteriocin Produced by Weissella cibaria

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...

Antibacterial activity and characterization of bacteriocin of Bacillus mycoides isolated from whey

Bacteriocin produced by Bacillus mycoides isolated from whey showed strong inhibition against food borne serious pathogens, Listeria monocytogenes and Leuconostoc mesenteroides. Antibacterial substance was partially purified by salt saturation method. Partially purified bacteriocin withstood temperature up to 100°C, found active at wider pH range (4 to 11) and was sensitive to trypsin. This inh...
