The use of LAB for protective culture has some advantages on bacteriocin
and its other antimicrobial metabolites, as the living LAB can adopt itself to the changing environment and conditions of foods during processing and storage, producing antimicrobials and other metabolites constantly (Settanni and Corsetti, 2008).
Possibility of usage of lactic acid bacteria (LAB) as substrates of other chemical preservatives of food and production of bacteriocin
which is of great economic interest had been reported earlier (Admas, 1999).
antiseptic drug has been produced in this research by using lactobacillus, and it has been stabilized on the produced nanofibers at the same time with the beginning of electrospinning process.
Amino acid and nucleotide sequence, adjacent genes, and heterologous expression of hiracin JM79, a sec-dependent bacteriocin
produced by Enterococcus hirae DCH5, isolated from Mallard ducks (Anasplatyrhynchos).
Antimicrobial activity and occurrence of bacteriocin
structural genes in Enterococcus spp.
Diverse mechanisms describing the bacteriocin
mode of action were outlined but the cell membrane still remains the main target of these AMPs.
Initially the isolate was screened for its ability to produce biosurfactant and bacteriocin
using various qualitative and quantitative methods.
Plates were incubated for additional 18h and then checked for clear inhibition zones around spots of the presumed bacteriocin
Next, the culture was centrifuged at 5500 rpm (9000g) for 5 -10 min and the clear supernatant was used as an unpurified bacteriocin
If inhibition zone were found in the third well, the isolates were considered to be able to produce bacteriocin
like substances) (18).
