Interaction between Lactiplantibacillus plantarum RX-8 and Wickerhamomyces anomalus Y-5 under co-culture by proteomics analysis

ABSTRACT: In present study, it was found that the co-culture of Wickerhamomyces anomalus Y-5 and L. plantarum RX-8 could enhance bacteriocin production. To analyze the interaction between W. anomalus Y-5 and L. plantarum RX-8, a quantitative proteomic approach was used to analyze and compare the proteome in L. plantarum RX-8 and W. anomalus Y-5 under mono-culture and co-culture. In total, 339 differently expressed proteins (DEPs) were screened in comparison of L. plantarum RX-8 under mono-culture and co-culture, 645 proteins of W. anomalus Y-5 changed in mono-culture and co-culture. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis indicated that DEPs participated in various metabolic pathways such as PTS system, glycolysis, galactose metabolism, glutamate, aspartate, arginine and cysteine metabolism etc. These pathways were related to inducing mechanism on improving bacteriocin production by co-culture. Quantitative proteomic analysis-based strategies can therefore provide further evidence for new regulated targets to improve the production of bacteriocins.

Differences between static supernatant-, static biofilm- and flow biofilm-cells of two Lactiplantibacillus plantarum strains.

Project description:This study was conducted to analyze phenotypic and proteomic differences of two Lactiplantibacillus plantarum strains (WCFS1, model strain from human saliva, and CIP104448, stool isolate) when a biofilm was produced under static conditions (well researched), or with the addition of flow (novel).

Proteomic profiling of extracellular vesicles of the Lactiplantibacillus plantarum strains

Project description:The study was conducted on a model of Lactiplantibacillus plantarum, one of the most studied species widely used in the food industry as a probiotic microorganism and/or microbial starter culture. As a result of step-by-step selection from the L. plantarum 8p-a3 strain isolated from the «Lactobacterin» probiotic, the L. plantarum 8p-a3-Clr-Amx strain was obtained, showing increased resistance, compared with the parent strain, to amoxicillin-clavulanic acid (MIC 20 mcg/ml) and clarithromycin (MIC 10 mcg/ml). The L. plantarum strain DMC-S1 was isolated from the intestine of Drosophila melanogaster Canton-S line. Extracellular vesicles of this bacterium can play a significant role in the drug-resistance development and host-microbe interactions.

Fermentation of soy juice by Lactiplantibacillus plantarum confers a yogurt-like texture, flavours and health-promoting metabolites

Project description:The aim of the study was to decipher metabolisms responsible (i) for the peculiar adaptation of L. plantarum during soy juice fermentation and (ii) for the release of aroma compounds, amino and short-chain fatty acid, and metabolites with health-promoting properties in soy yogurt. The strategy was the sequencing and annotation of a strain (L. plantarum CIRM-BIA777, PRJEB77707) able to degrade galacto- oligosaccharides, the sampling of soy yogurt, RNA-seq to identify differentially expressed genes of L. plantarum and corresponding metabolisms throughout the kinetics of fermentation. Acids and volatile compounds were also quantified.

Transcriptome response of Salmonella enterica subsp. enterica serovar Typhimurium N-15 and Bifidobacterium thermophilum RBL67 in co-culture

Project description:Bifidobacterium thermophilum RBL67 (RBL67), a human fecal isolate and promising probiotic candidate, showed antagonistic and protective effects against Salmonella and Listeria in vitro. However, the underlying mechanisms fostering these health-related effects remain unknown. Therefor the transcriptome response of RBL67 and Salmonella enterica subsp. enterica serovar Typhimurium N-15 (N-15) in co-culture compared to the response in their respective mono-cultures. RNA was extracted from culture samples taken after 4 (N-15) or 5 h (RBL67) and RNAseq was performed on an Illumina HiSeq 2000 sequencer. Three biological replciates were performed resulting in 12 data sets: 3 RBL67 mono culture, 3 N15 mono-culture, 3 RBL67 co-culture, 3 N15 co-culture. Our study provided first insights into probiotic-pathogen interaction on transcriptional level and suggests a mechanism for how probiotic organisms can protect the host from infections. RNA was extracted from culture samples taken after 4 (N-15) or 5 h (RBL67) and RNAseq was performed on an Illumina HiSeq 2000 sequencer.
