Garvieacin Q, a novel class II bacteriocin from Lactococcus garvieae BCC 43578.
Lactococcus garvieae BCC 43578 produces a novel class II bacteriocin, garvieacin Q (GarQ), 70 amino acids in length and containing a 20-amino-acid N-terminal leader peptide. It is cleaved at the Gly-Gly site to generate the mature GarQ (5,339 Da), which is especially inhibitory against Listeria monocytogenes ATCC 19115 and other L. garvieae strains.
متن کاملGenome sequence of the bacteriocin-producing strain Lactococcus garvieae DCC43.
This work describes the draft genome sequence of Lactococcus garvieae DCC43. The 2.2-Mb draft genome contains 2,227 predicted protein-coding genes, among which is a region encoding the bacteriocin garvicin ML. No antibiotic resistance genes or capsule-related virulence genes were identified. Two plasmid replication regions indicate that this strain likely contains plasmids. Comparative genomics...
متن کاملIdentification and Characterization of Lactococcus Garvieae and Antimicrobial Activity of Its Bacteriocin Isolated from Cow’s Milk
This study was conducted to isolate lactic acid bacteria (LAB) from cow’s milk and characterize through morphological, physiological, biochemical, carbohydrate fermentation and its antimicrobial property. The bacteria were isolated by serial dilution of milk samples and confirmed through biochemical, physiological and 16s rRNA sequencing. The antibiotic susceptibility test of bacteria, antimicr...
متن کاملGenome sequence of Lactococcus garvieae IPLA 31405, a bacteriocin-producing, tetracycline-resistant strain isolated from a raw-milk cheese.
This work describes the draft genome sequence of Lactococcus garvieae IPLA 31405, isolated from a traditional Spanish cheese. The genome contains a lactose-galactose operon, a bacteriocin locus, two integrated phages, a transposon harboring an active tet(M) gene, and two theta-type plasmid replicons. Genes encoding virulence factors were not recorded.
متن کاملLactococcin Q, a novel two-peptide bacteriocin produced by Lactococcus lactis QU 4.
A bacteriocin-producing strain, Lactococcus lactis QU 4, was isolated from corn. The bacteriocin, termed lactococcin Q, showed antibacterial activity only against L. lactis strains among a wide range of gram-positive indicator strains tested. Lactococcin Q was purified by acetone precipitation, cation exchange chromatography, and reverse-phase chromatography. Lactococcin Q consisted of two pept...
