Numerous studies have connected the gut microbiome with diet-induced obesity; however, mechanistic explanations for the host-microbial interactions are needed. Perry et al. (2016) present studies suggesting that microbially produced acetate (MPA) increases post-prandial insulin release via a sequential and integrated gut, brain, and pancreatic signaling network promoting energy retention.

The short-chain fatty acids (SCFAs) propionate and butyrate have beneficial health effects, are produced in large amounts by microbial metabolism and have been identified as unique acyl lysine histone marks. To better understand the function of these modifications, we used chromatin immunoprecipitation followed by sequencing to map the genome-wide location of four short-chain acyl histone marks, H3K18pr, H3K18bu, H4K12pr and H4K12bu, in treated and untreated colorectal cancer (CRC) and normal cells as well as in mouse intestines in vivo. We correlate these marks with open chromatin regions and gene expression to access the function of the target regions.

Lactic acid bacteria (LAB), traditionally consumed as fermented foods, are now being applied to the medical field beyond health-functional food as probiotics. Therefore, it is necessary to continuously discover and evaluate new strains with suitable probiotic characteristics, mainly focusing on safety. In this study, we isolated eight new strains from postmenopausal vaginal fluid using culturomics approaches, an emerging area of interest.

Nickel (Ni) is required in trace amounts (less than 500 µg kg) in plants to regulate metabolic processes, the immune system, and to act as an enzymatic catalytic cofactor. Conversely, when nickel is present in high concentration, it is considered as a toxic substance. Excessive human nickel exposure occurs through ingestion, inhalation, and skin contact, ultimately leading to respiratory, cardiovascular, and chronic kidney diseases.

Background: Parageobacillus thermoglucosidasius is a facultatively anaerobic thermophile that is able to produce hydrogen (H) gas from the oxidation of carbon monoxide through the water-gas shift reaction when grown under anaerobic conditions. The water-gas shift (WGS) reaction is driven by a carbon monoxide dehydrogenase-hydrogenase enzyme complex. Previous experiments exploring hydrogenogenesis with P.

Cellobiose lipids (CBLs) are a class of glycolipid biosurfactants produced by various fungal strains. These compounds have gained significant interest due to their surface-active and antifungal properties, which are comparable to traditional synthetic surfactants and antimicrobials. Despite their potential applicability in various cosmetic, pharmaceutical, and agricultural formulations, significantly less research has been focused on their production and purification in comparison to other glycolipid biosurfactants, such as mannosylerythritol lipids (MELs) and sophorolipids.
