Ethanologenesis from glycerol by the gut acetogen Blautia schinkii

Environmental Microbiology, Volume 25, Issue 12, Page 3577-3591, December 2023., 2023
We analysed the glycerol metabolism of Blautia schinkii with physiological, biochemical and gene expression studies. At low glycerol concentrations acetate and ethanol are formed in equal amounts. However, at high glycerol concentrations only ethanol is formed presenting a novel feature of human gut bacteria: Homoethanologenesis from glycerol ...

Effects of ex situ conservation on diversity and function of the gut microbiota of the Tibetan wild ass (Equus kiang)

Integrative Zoology, Volume 18, Issue 6, Page 1089-1104, November 2023., 2023
The Tibetan wild ass is the only wild Perissodactyla herbivore in the Qinghai‐Tibet Plateau. Abstract Ex situ conservation is the main method for the protection of endangered wildlife. To explore the effect of ex situ conservation on the gut microbiota of the kiang (Equus kiang), metagenomic sequencing combined with bioinformatics analysis was used to ...

Subtle sequence differences between two interacting σ54‐dependent regulators lead to different activation mechanisms

The FEBS Journal, Volume 289, Issue 23, Page 7582-7604, December 2022., 2022
RedR1 and RedR2 are bacterial enhancer‐binding proteins than only differ in 17 residues (labelled orange and lilac) but are controlled through opposite mechanisms: RedR2 is constitutive and kept inactive by binding the membrane protein BtdS. RedR1 is negatively controlled by its N‐terminal domain.

Cycling of reduced phosphorus compounds in soil and potential impacts of climate change

European Journal of Soil Science, Volume 72, Issue 6, Page 2517-2537, November 2021., 2021
Abstract Soil phosphorus (P) remains an ever‐increasing topic of importance, notably for its key role as a nutrient for driving food production but with parallel concerns over damaging water quality, all against a backdrop of uncertainty of long‐term rock phosphate supplies.

Oral microbiome shifts during pregnancy and adverse pregnancy outcomes: Hormonal and Immunologic changes at play

Periodontology 2000, Volume 87, Issue 1, Page 276-281, October 2021., 2021
Abstract Because of hormonal and immunologic changes, there are significant changes in the oral microbiome that emerge during pregnancy. Recent evidence further suggests that there is an association between the presence of periodontal disease and a pregnancy‐associated oral dysbiosis. Although this oral dysbiosis and pathogenic periodontal bacteria are

Nonpuerperal breast abscess due to Prevotella bivia

Clinical Case Reports, Volume 8, Issue 8, Page 1399-1402, August 2020., 2020
Contrary to puerperal abscess, nonpuerperal breast abscess is often caused by anaerobic bacteria; polymicrobial aerobic‐anaerobic infections are also frequent. Empiric first‐choice treatment with broad‐spectrum antibiotics should be considered. Abstract Contrary to puerperal abscess, nonpuerperal breast abscess is often caused by anaerobic bacteria ...
