The promising use of bacteriocin
and other metabolites from LAB has proved itself as a good natural preservative.
producing strain) is active against bacterial pathogens.
Based on the experimental results, the release of bacteriocin
from nanofibers and its antibacterial activity significantly reduce the number of bacteria.
This is due to competition for nutrients and the presence of inhibitors produced by the starter culture, including organic acids, hydrogen peroxide and bacteriocins
(O'Sullivan et al., 2002).
Sometimes a simple mechanism such as large colony size gives a microbe a competitive edge (Li & Li 2012), and other times a more sophisticated mechanism such as bacteriocins
is employed (Majeed et al.
The objective of the present study is to isolate a bacteriocin
producing bacterium with a wide spectrum antimicrobial property.
Antibacterial Property of Bacteriocin
plantarum NCIM2084 produced a bacteriocin
(plantaricin LP84) resistant to heat and catalase and was able to inhibit E.
They produce bacteriocins
, bioactive peptides with antimicrobial activity against Gram-positive bacteria such as Staphylococcus aureus, Bacillus cereus, Listeria monocytogenes and Clostridium botulinum (Nettles and Barefoot, 1993) and have been shown to protect mice against P.
To determine which substance (Lactic acid/acetic acids, [H.sub.2][O.sub.2], Bacteriocins
like substances) cause the antibacterial activity, CFS of the L.
