and probiotic activity.
An objective of present study was the screening and identification of bacteriocin
producing LAB from meat samples and to examine antibacterial activity of isolated bacteria (Lewus et al., 1991).
Antilisterial activity has been described for Enterococcus spp., which may synthesize several antimicrobial substances, such as organic acids, hydrogen peroxide, carbon dioxide, diacetyl, acetaldehyde and bacteriocins
, called enterocins (Naidu et al., 1999).
Technological characterization of bacteriocin
producing Lactococucus lactis strains employed to control Listeria monocytogenes in Cottage cheese.

. ISME J.
Peptone yeast beef medium (PYB in g/L: 10 g peptone, 5 g yeast extract and 3 g beef extract) was used as a bacteriocin
core production medium.
In the present study, isolate (Lactobacillus casei MRTL3) possessing simultaneous bacteriocin
and biosurfactant-producing ability was identified and characterized.
However, using cell-free supernatants treated with catalase to eliminate the possible presence of hydrogen peroxide and neutralized, no strain produced bacteriocin
and, consequently, no strain was able to inhibit E.
aeruginosa isolates for antibiotic sensitivity, nanoparticle sensitivity and susceptibility to Lactobacillus bacteriocins
in culture supernates.
production by lactic acid bacteria isolated from fish, seafood and fish products.
Isolation of bacteriocin
producing lactic acid bacteria from fish and its antimicrobial activity.
The strain Enterococcus faecium T136 produces two bacteriocins
: enterocin A, a member of the pediocin family of bacteriocins
, and a relatively new bacteriocin
called enterocin B.
