New type non-lantibiotic bacteriocins: circular and leaderless bacteriocins

Beneficial Microbes, 2012
Bacteriocins are antimicrobial peptides that are ribosomally synthesised by bacteria. Bacteriocins produced by Gram-positive bacteria, including lactic acid bacteria, are under focus as the next generation of safe natural biopreservatives and as therapeutic alternatives to antibiotics.

Mining, heterologous expression, purification, antibactericidal mechanism, and application of bacteriocins: A review.

Comprehensive Reviews in Food Science and Food Safety, 2020
Bacteriocins are generally considered as low-molecular-weight ribosomal peptides or proteins synthesized by G+ and G- bacteria that inhibit or kill other related or unrelated microorganisms.

Bacteriocins and Bacteriocin-Like Substances from Lactobacillus

1994
Grossowics et al. (1947), Wager (1948), White & Hill (1949), Ritter (1951), Wheater et al. (1951, 1952), Polonskaya (1952) and Guillot (1958) were among the first investigators reporting on antibacterial activity associated with Lactobacillus spp. (Lb. acidophilus, Lb. delbrueckii subsp. lactis, Lb. helveticus).

Plantaricin bacteriocins: As safe alternative antimicrobial peptides in food preservation—A review

, 2020
Many peptides are excreted by gram‐positive (+) and gram‐negative (−) bacteria, possessing antimicrobial properties, called bacteriocins. Common bacterial species produce bacteriocins are called lactic acid bacteria.

Bacteriocin production and sensitivity

Folia Microbiologica, 2004
Using an overlay test the production of bacteriocin-like activity and resistance was found in 6 of the total of 7 isolates (5 enterococcal and 2 streptococcal). The majority of strains were sensitive to all bacteriocin producers tested. After acetone precipitation, bacteriocin precipitates were tested for thermal stability.

Acinetobacter bacteriocin typing

Journal of Hospital Infection, 1986
A technique for typing Acinetobacter sp. by bacteriocin production has been developed. One hundred and seventy-six cultures from patients in outbreaks, in the community and environmental sources were identified, tested for sensitivity to gentamicin and bacteriocin typed; 154 were A. anitratus and the remainder A.lwoffi.

Bacteriocins of ruminal bacteria

Folia Microbiologica, 2001
Similar sequences of distribution of structural genes encoding enterocin A (isolated from the ruminal strain E. faecium BC25) and enterolysin A (isolated from the ruminal amylolytic strain S. bovis II/1) were demonstrated by PCR using oligonucleotide primers specific for these bacteriocins within the ruminal enterococcal and streptococcal strains ...

Purification of Antilisterial Bacteriocins

2004
In recent years, numerous contamination outbreaks, involving various pathogens (i.e., Listeria and Salmonella), have increased concern over food preservation. Research efforts have focused on the discovery of new molecules targeting such foodborne pathogens and therefore able to inhibit and or kill them.

Export of Bacteriocins

2003
Bacteriocins are bactericidal proteins that are produced by bacteria. They usually kill only bacterial cells that are closely related to the producing bacteria. The narrow host range is determined by the sophisticated uptake mechanisms that these proteins use to enter susceptible bacterial cells.
