“…According to the comparisons with the complete 16S rRNA gene sequences in the EzTaxon database, the highest level of sequence similarity occurred with Flavobacterium artemisiae SYP-B1015 T (98.2%) (Zhao et al 2018 ), followed by Flavobacterium crocinum HYN0056 T (97.4%) (Baek et al 2018 ) and Flavobacterium compostarboris 15C3 T (97.3%) (Kim et al 2012a , b ). The 16S rRNA gene based phylogeny tree suggests that strain Kb82 T forms a distinct phyletic lineage within Flavobacterium genus (Fig.…”

A Gram-negative bacterial strain, named Kb82, was isolated from agricultural soil and a polyphasic approach was used for characterisation and to determine its taxonomic position. Based on 16S rRNA gene sequence analysis, the highest similarity was found with Flavobacterium artemisiae SYP-B1015 (98.2%). The highest ANI (83.3%) and dDDH (26.5%) values were found with Flavobacterium ginsenosidimutans THG 01 and Flavobacterium fluviale HYN0086T, respectively. The isolate is aerobic with rod-shaped cells, positive for catalase and negative for oxidase tests. The DNA G+C content is 34.7 mol%. The only isoprenoid quinone is menaquinone 6 (MK-6). The major fatty acids are iso-C15:0, summed feature 3 (C16:1ω7c/C16:1ω6c) and iso-C17:0 3OH. The major polar lipid is phosphatidylethanolamine. On the bases of phenotypic characteristics and analysis of 16S rRNA gene sequences, it is concluded that strain Kb82T represents a novel species in the Flavobacterium genus, for which the name Flavobacterium hungaricum sp. nov. is proposed. The type strain of the species is strain Kb82T (= LMG 31576T = NCAIM B.02635T).

Bile acids (BA) are among the most abundant metabolites produced by the gut microbiome. Primary BAs produced in the liver are converted by gut bacterial 7-α-dehydroxylation into secondary BAs, which can differentially regulate host health via signaling based on their varying affinity for BA receptors. Despite the importance of secondary BAs in host health, the regulation of 7-α-dehydroxylation and the role of diet in modulating this process is incompletely defined. Understanding this process could lead to dietary guidelines that beneficially shift BA metabolism. Dietary fiber regulates gut microbial composition and metabolite production. We tested the hypothesis that feeding mice a diet rich in a fermentable dietary fiber, resistant starch (RS), would alter gut bacterial BA metabolism. Male and female wild-type mice were fed a diet supplemented with RS or an isocaloric control diet (IC). Metabolic parameters were similar between groups. RS supplementation increased gut luminal deoxycholic acid (DCA) abundance. However, gut luminal cholic acid (CA) abundance, the substrate for 7-α-dehydroxylation in DCA production, was unaltered by RS. Further, RS supplementation did not change the mRNA expression of hepatic BA producing enzymes or ileal BA transporters. Metagenomic assessment of gut bacterial composition revealed no change in the relative abundance of bacteria known to perform 7-α-dehydroxylation. P. ginsenosidimutans and P. multiformis were positively correlated with gut luminal DCA abundance and increased in response to RS supplementation. These data demonstrate that RS supplementation enriches gut luminal DCA abundance without increasing the relative abundance of bacteria known to perform 7-α-dehydroxylation.

“…S1–S11) were isolated and characterized. The closest relatives of some of the newly described taxa were previously isolated from aquatic environments, such as Rhizobacter profundi DS48-6-5 T ( 74 ), isolated from freshwater sediment in Korea; Aquabacterium pictum W35 T ( 75 ), isolated from Tama River in Japan; Aquincola tetriaricarbonis L10 T ( 76 ), isolated from contaminated groundwater (Germany); or Flavobacterium album HYN0059 T ( 77 ), isolated from a freshwater lake (Korea). Other closest relatives were described in different types of soils, such as Hymenobacter psychrotolerans Tibet-IIU11 T ( 78 ) in permafrost sediment in China, Sphingomonas suaedae XS-10 T ( 79 ) in the rhizosphere of Suaeda salsa (China), Phenylobacterium immobile E T ( 80 ) in chloridazon-contaminated soil, and Phenylobacterium muchangoponense A8 T ( 81 ) in beach soil (Korea), or Pseudomonas campi S1-A32-2 T ( 82 ) in grassland soil.…”

The mine Svornost in Jáchymov (Joachimstahl), Czech Republic is a former silver-uranium mine and the world’s first and for a long time only radium mine, nowadays the deepest mine devoted to the extraction of water which is saturated with radon and has therapeutic benefits given its chemical properties. This healing water, which is approximately 13 thousand years old, is used under medical supervision for the treatment of patients with neurological and rheumatic disorders.
