One-step transformation of CO to methane by Escherichia coli with a synthetic biomethanation module.
Biochem Biophys Res Commun
January 2025
The biomethanation process is widely recognized as a significant approach to mitigating carbon dioxide emissions while simultaneously generating methane. However, only a few microorganisms that required intricate culturing conditions were identified for biomethanation. Here, Escherichia coli that featured easy cultivation and versatile chassis was genetically modified for biomethanation for the first time.

Its health hazards extend to dangerous complications, which mostly end in death according to statistics around the world. Tobacco use is influenced by several factors, which may include social pressures from peers, family influences, and media portrayals of smoking.

- Ammonia (NH) is a toxic gas that negatively impacts the environment and the immune systems of chickens, although the exact mechanisms behind these effects are not fully understood.
- In this study, researchers used advanced imaging techniques to observe structural damage in the bursa of Fabricius and thymus in chickens exposed to NH, including swollen mitochondria and other cellular changes.
- The exposure also led to an enhanced immune response, activating specific inflammatory pathways and upregulating important genes related to inflammation, which may inform future treatments to support poultry health.
Article Synopsis
- The text highlights the growing interest in lignin, a biopolymer, due to its potential for creating eco-friendly products, with β-etherases being critical for breaking down its complex structure.
- It provides an overview of recent advancements in β-etherase research, including their substrate selectivity, oxidative activity, and engineering methods, which enhance our understanding of their applications.
- The review also addresses the challenges and promising future of β-etherases in lignin valorization for sustainable and economically viable biorefinery processes.
Background: Levofloxacin, a fluoroquinolone, is an extensively used antibiotic effective against both positively and negatively staining bacteria. It works by inhibiting bacterial topoisomerase type II and topoisomerase type IV, resulting in impaired DNA synthesis and bacterial cell death. Eryptosis is another term for apoptotic cell death of erythrocyte marked by cell shrinkage, phosphatidylserine (PS) flipping, and membrane blebbing.
