Sentences with word «bacteriocins»

Most P. aeruginosa produce bacteriocins called pyocins, typically several of them.

These bacteria compete with pathogenic bacteria for nutrients, as well as produce inhibitory substances such as bacteriocins and organic acids that can kill or limit the growth of bacterial pathogens (9).

The model organism Pseudomonas aeruginosa is famous for multidrug resistance, but compounds called bacteriocins may be able to outflank it.

Natural micro-flora (friendly bacteria) that may help the digestion process, thus providing more efficient utilization of food and produce bacteriocins which act as natural antibiotics.

Perhaps bacteriocins, if not antibiotics, exist not to help bacteria but rather to ensure their own survival.

«When people again started proposing bacteriocins as novel therapeutics, we wondered if they could evolve resistance,» said Inglis, who is now a research scientist at Washington University in St. Louis.

The presence of biosynthetic genes for bacteriocins is common to all genomes, except for microcin in UM270.

Bacteriocin biosynthesis contributes to the anti-inflammatory capacities of probiotic Lactobacillus plantarum — X. Yin — Beneficial Microbes

Lactobacillus reuteri is probably most famous because of the three bacteriocin substances that it produces: reuterin, reutericin, and reutericylin.

They fight other bacteria, by releasing substances that are toxic to other bacteria, named bacteriocins, to kill the bad bacteria.

I'd like to think it creates bacteriocins (its own natural antibiotics) and pH changes that can then allow Bifido to properly reproduce and thrive as indicated.

Helps the digestion process, thus providing more efficient utilization of food and produce bacteriocins which act as natural antibiotics against bad bacteria.

Moreover, the team is now isolating and studying the bacteriocins, which Dr. Lee says «have tremendous potential.»

One possible tool: bacteriocins — natural, bacteria - derived, narrow - spectrum antibiotics.

In contrast, 99.9 percent of bacteria produce bacteriocins.

To find out, he and his colleagues ran an «evolution experiment,» growing a strain of bacteria sensitive to a bacteriocin in the presence of a strain that produces the bacteriocin but is itself immune to it.

They're not the same thing at all, but they kill bacteria, so we call them bacteriocins.»

'' «Bacteriocin» is a catch - all term that describes functionally and structurally disparate things,» he said.

In an experiment published in 2013, Inglis and colleagues showed that bacteriocins can act primarily as selfish genetic elements promoting their own transmission in the population.

Inglis attributes this success to the fact that the bacteriocin targets a receptor on the bacteria's cell surface that is essential to its survival.

One group of compounds again in the news is the bacteriocins, potent antimicrobial peptides (bits of proteins) that bacteria secrete that kill closely related bacteria.

«Some bacteriocins poke holes in the cell membrane, some degrade DNA.

Their results, published Feb. 26 in the online edition of ISME Journal, the journal of the International Society Microbial Ecology, showed this bacteriocin isn't resistance proof, but that strains that became resistant to it also became weaker, Inglis said.

Because they are specific to particular strains of bacteria, bacteriocins will not replace general antibiotics, but they could be used to target strains of multidrug resistant or highly virulent bacteria.

The canonical answer, biologist R. Fredrik Inglis said, is that antibiotics kill a broad spectrum of bacteria — they might, for example, kill all susceptible gram - negative bacteria — but bacteriocins are narrow spectrum agents, inhibiting the growth of only closely related bacterial strains.

As evolutionarily conserved weapons, bacteriocins have great potential as alternatives to conventional antibiotics.»

Biological control mechanisms include synthesis of secondary metabolites against bacterial and fungal pathogens, including toxins and bacteriocins.
