Antimicrobial properties of the peptide substance Bacillus Subtilis PSF-19

26.08.2019

Annotation

the subject of the study is a strain of Bacillus subtilis PSF-19 isolated by us from vegetable raw materials (Passiflora preparation), which is capable of producing antimicrobial substance (AMV) suppressing pathogenic bacteria. The article discusses the method and conditions of extraction from the culture fluid fraction of AMV, active against Listeria monocytogenes – one of the dangerous intestinal pathogens that infect food. Using biochemical methods and mass spectroscopy, the molecular weight and the peptide nature of the active fraction of AMV were determined. A fraction of AMV with a molec...
