Postbiotic Supernatants From Psychobiotic Strains Modulate Antioxidant and Serotonergic Responses

eFood, Volume 7, Issue 3, June 2026.
Cell‐free postbiotic supernatants obtained from psychobiotic strains exhibit strain‐dependent antioxidant and serotonergic effects. SCFA‐rich metabolites enhance antioxidant protection and modulate serotonin release in enterochromaffin cells, supporting their potential as functional ingredients for gut and brain health.

Antibacterial Activities of Bacteriocins: Application in Foods and Pharmaceuticals

Frontiers in Microbiology, 2014
Bacteriocins are a kind of ribosomal synthesized antimicrobial peptides produced by bacteria, which can kill or inhibit bacterial strains closely-related or non-related to produced bacteria, but will not harm the bacteria themselves by specific immunity ...

Phase transition in a spatial Lotka-Volterra model

, 2000
Spatial evolution is investigated in a simulated system of nine competing and mutating bacterium strains, which mimics the biochemical war among bacteria capable of producing two different bacteriocins (toxins) at most.

In vitro screening of probiotic lactic acid bacteria and prebiotic glucooligosaccharides to select effective synbiotics [PDF]

, 2010
Probiotics and prebiotics have been demonstrated to positively modulate the intestinal microflora and could promote host health. Although some studies have been performed on combinations of probiotics and prebiotics, constituting synbiotics, results on ...

Nanoshell Fabrication Techniques for Probiotic Encapsulation: A Comprehensive Review

eFood, Volume 7, Issue 3, June 2026.
ABSTRACT Probiotics, beneficial microorganisms, confer numerous health benefits when administered. However, their efficacy is hindered by harsh gut conditions, including acidity, bile acids, and enzymatic degradation. To overcome these challenges, encapsulation and nanoshell technology have emerged as a pivotal strategy to enhance probiotic stability ...

Microbial Safety of Legumes—A Review: Bacterial Contamination, Foodborne Outbreaks, and Traditional and Innovative Mitigation Strategies

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Demand for plant‐based foods, including legumes, is growing as a result of consumer preferences shifting toward food sustainability and plant‐based, protein‐rich foods. However, to ensure the food safety of such alternatives, assessing the prevalence of foodborne pathogens related to these products is critical, especially with their increasing

Revisiting the Multifaceted Roles of Bacteriocins

Microbial Ecology
AbstractBacteriocins are gene-encoded antimicrobial peptides produced by bacteria. These peptides are heterogeneous in terms of structure, antimicrobial activities, biosynthetic clusters, and regulatory mechanisms. Bacteriocins are widespread in nature and may contribute to microbial diversity due to their capacity to target specific bacteria ...

Kefir: A Potential Gut Microbiota Modulator: A Systematic Review of Human Interventional Studies

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Daily cow's milk kefir intake transiently enriches gut microbiota, modulates the intestinal environment by increasing SCFA and reducing pH and oxygen, and exerts antimicrobial effects via SCFAs, bacteriocins, exopolysaccharides, and microbial fractions, highlighting its potential for gut health promotion.
