Preparation of CdS@C Photocatalyst Using Phytoaccumulation Cd Recycled From Contaminated Wastewater

open access: yesFrontiers in Chemistry, 2021
Cadmium is one of the most toxic heavy metal contaminants in soils and water bodies and poses a serious threat to ecosystems and humans. However, cadmium is also an important resource widely used in many industries. The recovery of cadmium in the form of

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Methanogenesis in the presence of oxygenic photosynthetic bacteria may contribute to global methane cycle

open access: yesNature Communications
Accumulating evidences are challenging the paradigm that methane in surface water primarily stems from the anaerobic transformation of organic matters.

Active prophages as key drivers of microbial adaptation in global soil ecosystems

open access: yesmBio
Soils harbor the most complex microbial diversity on Earth, in which bacteria are ubiquitously infected by temperate phages. While integrated prophages often enhance host fitness, active (inducible) prophages are traditionally perceived as “molecular ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Impacts of Land-Use Change from Primary Forest to Farmland on the Storage of Soil Organic Carbon

open access: yesApplied Sciences
Land-use change (LUC) is a significant contributor to the increase in atmospheric CO2 concentrations, with previous studies demonstrating its profound impact on soil organic carbon (SOC).

An obesity-associated gut microbiome reprograms the intestinal epigenome and leads to altered colonic gene expression

open access: yesGenome Biology, 2018
Background The gut microbiome, a key constituent of the colonic environment, has been implicated as an important modulator of human health. The eukaryotic epigenome is postulated to respond to environmental stimuli through alterations in chromatin ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
