High‐Resolution LC–MS/MS Characterization of Budmunchiamine‐Type Alkaloids in Albizia niopoides

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Budmunchiamines are macrocyclic spermine alkaloids that constitute a distinctive class of polyamine natural products predominantly found in species of the genus Albizia. Comprehensive characterization of these compounds remains challenging because of their structural diversity and the limited availability of reference standards. This

The Mycorrhizal Fungal Species Funneliformis mosseae Reshapes Rhizosphere Microbial Metabolic Pathways of Soybeans Under Tetracycline Stress

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
The presence of residual antibiotics (tetracycline) poses a threat to food safety in the black soils of northeastern China and a mycorrhizal fungal species Funneliformis mosseae could mitigate the negative effects. This study tracked the changes in soybeans' rhizospheric microbial profiles and the associated metabolites during the bioremediation ...

Insights Into the Antibiofilm Activity of Carbon Quantum Dots Against a Panel of Different Microorganisms: A Review

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carbon quantum dots (CDs) have emerged as versatile nanoplatforms for combating biofilm‐associated infections through multiple mechanisms, including EPS disruption, membrane damage, ROS generation, and quorum sensing inhibition. This review highlights how CD physicochemical properties and surface engineering strategies influence antibiofilm activity ...
