Purification and amino acid sequences of piscicocins V1a and V1b, two class IIa bacteriocins secreted by Carnobacterium piscicola V1 that display significantly different levels of specific inhibitory activity
Article Abstract:
The bacteriocin piscicocin V1a has a molecular mass of 4,416 Da and contains 44 amino acid residues, while piscicocin V1b is a 4,526 Da peptide identical to carnobacteriocin BM1 of Carnobacterium piscicola. Both the bacteriocins contain the consensus YGNGV sequence. Their C-terminal is involved in membrane anchoring and the N-terminal in receptor recognition. The bacteriocins are bactericidal, and inhibit various gram-positive bacteria. Piscicocin V1a is more active than piscicocin V1b.

Quantitative detection of Listeria monocytogenes in biofilms by real-time PCR
Article Abstract:
A quantitative method based on a real-time PCR assay is developed to enumerate Listeria monocytogenes in biofilms. The number of L. monocytogenes detected growing in biofilms was recoded to be 6X10(super 2) CFU/cm(super 2).
