Catabolic System of Syringic Acid, a Key Intermediate of Lignin-Derived Aromatic Compounds, via a Novel Linear Pathway in <i>Pseudomonas</i> sp. NGC7 Open
Syringic acid (SA) is a key intermediate in the bacterial catabolism of syringyl lignin-derived aromatic compounds. However, bacterial SA catabolism remains largely unknown. Here, we investigated the SA catabolic system in Pseudomonas sp. …

Comparative Assessment of Biochar Stability Using Multiple Indicators Open
Biochar application is one strategy proposed to improve carbon sequestration in soil. Maintaining high carbon content in soil for a long period requires stable biochar. In this work, we assessed biochar stability by two methodologies, i.e.…
