The genus Lactobacillus comprises 261 species (at March 2020) that are extremely diverse at phenotypic, ecological and genotypic levels. This study evaluated the taxonomy of Lactobacillaceae Leuconostocaceae on basis whole genome sequences. Parameters were included core phylogeny, (conserved) pairwise average amino acid identity, clade-specific signature genes, physiological criteria ecology organisms. Based this polyphasic approach, we propose reclassification into 25 genera including...
To determine structure-function relationships of antibacterial phenolic acids and their metabolites produced by lactic acid bacteria (LAB).Minimum inhibitory concentrations (MICs) 6 hydroxybenzoic hydroxycinnamic were determined with Lactobacillus plantarum, hammesii, Escherichia coli Bacillus subtilis as indicator strains. The activity increased at lower pH. A decreasing number hydroxyl groups enhanced the acids, but had minor effects on acids. Substitution methoxy hydroxybenzoic, not...
This study aimed to identify phenolic acids and flavonoids in the red sorghum variety PAN 3860 determine changes their concentrations during fermentation with lactobacilli. Sorghum sourdoughs fermented two binary strain combinations, Lactobacillus plantarum casei or fermentum reuteri, were compared chemically acidified controls. Four glycerol esters tentatively identified, caffeoylglycerol, dicaffeoylglycerol, coumaroyl-caffeoylglycerol, coumaroyl-feruloylglycerol, that have previously not...
Background Particulate matter (PM) is a key pollutant in ambient air that has been associated with negative health conditions urban environments. The aim of this study was to examine the effects orally administered PM on gut microbiome and immune function under normal inflammatory conditions. Methods Wild-type 129/SvEv mice were gavaged Ottawa PM10 (EHC-93) for 7–14 days mucosal gene expression analyzed using Ingenuity Pathways software. Intestinal permeability measured by lactulose/mannitol...
Lactobacilli are used widely in food, feed, and health applications. The taxonomy of the genus Lactobacillus, however, is confounded by apparent lack physiological markers for phylogenetic groups lactobacilli unclear relationships between diverse groups. This study core pan-genomes 174 type strains Lactobacillus Pediococcus to establish identify metabolic properties differentiating genome tree separated homofermentative pediococci from heterofermentative lactobacilli. Aldolase...
The intestinal microbiota is involved in ulcerative colitis (UC) pathogenesis. Prebiotics are hypothesized to improve health through alterations gut composition and/or activity. Our aim was therefore determine if inulin-type fructans induce clinical benefits UC, and identify linked compositional functional shifts of the luminal (fecal) mucosal (biopsy) bacterial communities. Patients (n = 25) with mild/moderately active UC received 7.5 g 12) or 15 13) daily oral oligofructose-enriched inulin...
Abstract BACKGROUND Encapsulation is commonly used to protect probiotics against harsh stresses. Thus, the fabrication of microcapsules with special structure critical. In this work, S/O/W (solid‐in‐oil‐in‐water) emulsion were prepared for probiotics, butterfat containing as inner core and whey protein isolate fibrils (WPIF) antioxidants (epigallocatechin gallate, EGCG; glutathione, GSH) outer shell. RESULTS Based on high viscosity good emulsifying ability WPIF, dry well‐dispersed...
Microbial spoilage in meat impedes the development of sustainable food systems. However, our understanding origin microbes is limited. Here, we describe a detailed longitudinal study that assesses microbial dynamics processing facility using high-throughput culture-dependent and culture-independent approaches to reveal diversity, dispersal, persistence, biofilm formation spoilage-associated microbes. Culture-dependent revealed large diversity within facility, including 74 undescribed...
ABSTRACT The amino acid release was determined in wheat doughs supplied with salt, acid, dithiothreitol, or starter cultures to evaluate the relevance of concentration on bread flavor. Wheat flour proteinases almost linearly released acids and highest activity found acidified reduced doughs. effects concentrations depended their composition. Yeasts exhibited a high demand for acids, however, total were not markedly affected by lactic bacteria. individual contents pH during fermentation...
