Effects of pectin methyl-esterification on intestinal microbiota and its immunomodulatory properties in naive mice.

Pectins are dietary fibers that are attributed with several beneficial immunomodulatory effects. Depending on the degree of esterification (DE), pectins can be classified as high methoxyl pectin (HMP) or low methoxyl pectin (LMP). The aim of this study was to investigate the effects of pectin methyl-esterification on intestinal microbiota and its immunomodulatory properties in naive mice.

sp. nov. isolated from var. Rijnsburger, an onion landrace.

The novel, aerobic, Gram-stain-positive, rod-shaped bacterial strain, ZW T2_19, was isolated from an onion sample ( var. Rijnsburger). Analyses of the 16S rRNA gene sequence revealed that ZW T2_19 represented a member of the genus but may represent a novel species of this genus.

Time-dependent fermentation of different structural units of commercial pectins with intestinal bacteria.

Many of the proposed health-related properties of pectins are based on their fermentability in the large intestine, but detailed structure-related studies on pectin fermentation have not been reported so far. Here, pectin fermentation kinetics were studied with a focus on structurally different pectic polymers. Therefore, six commercial pectins from citrus, apple, and sugar beet were chemically characterized and fermented in in vitro fermentation assays with human fecal samples over different periods of time (0 h, 4 h, 24 h, 48 h).

Metabolism of glyphosate by the human fecal microbiota.

Glyphosate is the most frequently used herbicide worldwide and its application is under discussion due to health concerns. As humans may be exposed to glyphosate, the present study investigated the metabolism of glyphosate by the human fecal microbiota in vitro. Human fecal samples were collected from 15 different volunteers and fecal suspensions were prepared.

Metabolism of Daidzein and Genistein by Gut Bacteria of the Class .

The intake of isoflavones is presumed to be associated with health benefits in humans, but also potential adverse effects of isoflavones are controversially discussed. Isoflavones can be metabolized by gut bacteria leading to modulation of the bioactivity, such as estrogenic effects. Especially bacterial strains of the a well-known bacterial family of the human gut microbiota, are able to convert the isoflavone daidzein into equol.

Genome analysis reveals that the correct name of type strain DSM 22242 is Clavel 2013.

The strain DSM 22242 (=CCUG 57646=NR06) was taxonomically described in 2013 and named as Clavel 2013. In 2018, the name of the strain DSM 22242 was changed to (Clavel 2013) Nouioui 2018 due to taxonomic investigations of the closely related genera and within the phylum . However, the first whole draft genome of strain DSM 22242 was published by our group in 2019.

Microbiological findings in early and late implant loss: an observational clinical case-controlled study.

Background: Implants are a predictable and well-established treatment method in dentistry. Nevertheless, looking at possible failures of dental implants, early and late loss have to be distinguished. The intent of the study was to report microbiological findings on the surface of implants with severe peri-implantitis, which had to be explanted.

Influence of salt concentration and iodized table salt on the microbiota of fermented cucumbers.

The fermentation of vegetables is a traditional preservation method, that experiences a renaissance even in domestic households. Table salt is added to the fermentation batches to favor the growth of lactic acid bacteria usually. On an industrial scale, the fermentation brine is typically prepared with non-iodized table salt.

Antibiotics resistance and toxin profiles of Bacillus cereus-group isolates from fresh vegetables from German retail markets.

Background: This study aimed to evaluate the safety of raw vegetable products present on the German market regarding toxin-producing Bacillus cereus sensu lato (s.l.) group bacteria.

Gordonibacter faecihominis is a later heterotypic synonym of Gordonibacter urolithinfaciens.

In this study, the phylogenetic position of Gordonibacter faecihominis and Gordonibacter urolithinfaciens was investigated using phenotypic and molecular (rep-PCR, ARDRA, 16S rRNA gene sequencing and whole-genome sequencing) methods. Our results show that Gordonibacter faecihominis cannot be distinguished from Gordonibacter urolithinfaciens on the basis of the results of this polyphasic approach. Therefore, it is proposed that the two species Gordonibacter faecihominis and Gordonibacter urolithinfaciens belong to the same species.

Characterization of the microbiota and volatile components of kocho, a traditional fermented food of Ethiopia.

Kocho is a traditional product in Ethiopia, prepared by fermenting parts of 'false banana' plants (). Fermentation practices of kocho vary depending on the region of Ethiopia. In this study, 14 kocho samples originating from four different areas were investigated.

Whole-Genome Sequencing of the Fungus Penicillium citrinum Reveals the Biosynthesis Gene Cluster for the Mycotoxin Citrinin.

Penicillium citrinum is a food-contaminating ascomycete that consistently produces large amounts of the mycotoxin citrinin. Citrinin exhibits, besides its toxicity, antibiotic effects and thus potentially forces antibiotic resistance. Within the genome sequence, we identified the biosynthesis gene cluster for citrinin, which appears to be highly conserved within the genus .

Does the antidiabetic drug metformin affect embryo development and the health of brown trout ( f. )?

Background: Due to the rising number of type 2 diabetes patients, the antidiabetic drug, metformin is currently among those pharmaceuticals with the highest consumption rates worldwide. Via sewage-treatment plants, metformin enters surface waters where it is frequently detected in low concentrations (µg/L). Since possible adverse effects of this substance in aquatic organisms have been insufficiently explored to date, the aim of this study was to investigate the impact of metformin on health and development in brown trout ( f.
