Plants produce different types of phenolic compounds. The majority of these compounds are glycosylated. Phenolic O-glycosides are also common. Recently, C-glycosylation of phenolic compounds has received attention because of the biological importance of phenolic C-glycosides. To date, three classes of C-glycosyltransferases (CGTs) have been characterized based on the type of sugar acceptor: flavonoid CGT, coumarin CGT, and xanthone CGT. Phylogenetic analysis of glycosyltransferases has revealed that CGTs form a distinct class that is clearly different from that of O-glycosyltransferases. The characterized CGTs have been introduced into microbial systems to synthesize phenolic C-glycosides. Here, we review recent progress in the development of CGTs and their application in the synthesis of phenolic C-glycosides using microbial systems.

Objective: Few studies have investigated links between fraction exhaled nitric oxide (FeNO), the home and the school environment. FeNO is a biomarker of T helper 2 (Th2) airway inflammation. We investigated associations between FeNO and airway symptoms, allergies, household and classroom exposure among pupils in ten primary schools in Stockholm (N = 415).

This study investigated the spatial distribution patterns of airborne bacterial concentrations and microbial community structures in a modern commercial layer facility housing approximately 50,000 laying hens equipped with advanced environmental control systems. Air samples were systematically collected at 50 strategically distributed locations using a six-stage Andersen microbial air sampler, while environmental samples (dust, manure, intestinal contents) were characterized using 16S rRNA gene sequencing. Results demonstrated a distinct longitudinal gradient in airborne bacterial concentrations, progressively increasing from the air inlet (883±177 CFU/m³) to exhaust fans (12,650±813 CFU/m³), with a facility-wide mean concentration of 5,618±530 CFU/m³.

A vast amount of plastic waste enters the ocean every year and the Mediterranean Sea is particularly affected by this issue. Biodegradable polymers like poly(lactic acid) (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), may help mitigate this problem. We investigated bacterial biofilm development and succession on these polymers over one year in the Western Mediterranean Sea.

The primary goal of captive primate management is to ensure optimal health and welfare of the animals in our care. Given that the gut microbiome interacts closely with host metabolism, immunity, and even cognition, it represents a potentially powerful tool for identifying subtle changes in health status across a range of body systems simultaneously. However, thus far, it has not been widely tested or implemented as a monitoring tool.

Background: This study focuses on the detection and co-occurrence of Acanthamoeba and Klebsiella pneumoniae in freshwater river systems. Both microorganisms are known for their pathogenic potential, with Acanthamoeba capable of causing infections such as amoebic keratitis, and K. pneumoniae being a common cause of community infections.
