Abstract Kefir milk, known for its high nutritional value and health benefits, is traditionally produced by fermenting milk with kefir grains. These grains are a complex symbiotic community of lactic acid bacteria, acetic yeasts, other microorganisms. However, the intricate coexistence mechanisms within these microbial colonies remain mystery, posing challenges in predicting their biological functional traits. This uncertainty often leads to variability milk's quality safety. review delves into unique structural characteristics grains, particularly distinctive hollow structure. We propose hypotheses on formation, which appears be influenced aggregation behaviors members alliances.

DSFs are cis-2-unsaturated fatty acids containing acid carbon chains of various lengths and cis double-bond configurations. DSF-producing bacteria widely distributed in nature.Based on their genomic origins, DSF-mediated intraspecies communication pathways generally affiliated to three different groups, respectively represented by Xanthomonas campestris pv.

This communication, known as quorum sensing (QS), is mediated by the exchange of small signalling molecules called autoinducers. AI-2 QS, regulated metabolic enzyme LuxS (S-ribosylhomocysteine lyase), acts a universal mechanism across gram-positive gram-negative bacteria crucial for diverse bacterial processes. In this study, we demonstrated that in Streptococcus suis ( S. ), notable zoonotic pathogen, QS enhances galactose utilization, upregulates Leloir pathway capsular polysaccharide (CPS) precursor production, boosts CPS synthesis, leading increased resistance macrophage phagocytosis.
