Competitive Dominance by a Bacteriocin-Producing Vibrio harveyi Strain

Isolation of a Streptococcus mutans strain producing a novel bacteriocin.

A strain of Streptococcus mutans has been isolated that produces a bacteriocin with novel properties. Its antibiotic spectrum includes 123 of 124 strains of S. mutans tested and a variety of other gram-positive microorganisms. Experiments with dialysis membranes indicate that the molecular weight of the bacteriocin is less than 1,000. Mutants of the producer strain were obtained that are defici...

Bacteriocin-Producing Strain of Lactococcus lactis subsp. diacitilactis S50.

Lactococcus lactis subsp. diacitilactis S50 produces a bacteriocin, designated bacteriocin S50, which has a narrow antibacterial spectrum. It was active only against Lactococcus species, including a nisin producer exhibiting a bactericidal effect. The activity of bacteriocin S50 was sensitive to proteases. It retained antimicrobial activity after being heated to 100 degrees C for up to 60 min a...

Genome sequence of the bacteriocin-producing Lactobacillus curvatus strain CRL705.

Lactobacillus curvatus is one of the most prevalent lactic acid bacteria found in fermented meat products. Here, we present the draft genome sequence of Lactobacillus curvatus CRL705, a bacteriocin producer strain isolated from an Argentinean artisanal fermented sausage, which consists of 1,833,251 bp (GC content, 41.9%) and two circular plasmids of 12,342 bp (pRC12; GC, 43.9%) and 18,664 bp (p...

Genome 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...
