The ornithine-arginine cycle supported a toxic, metalimnic Planktothrix rubescens bloom

The study investigates the metabolic pathways of a toxic Planktothrix rubescens bloom using metagenomics and metabolomics, revealing the role of the ornithine-arginine cycle in its ecological success.

Non-redundant cardiolipin synthase family proteins shape lipid composition and stress resilience in Bacteroides fragilis

This study identifies non-redundant roles of ClsA and ClsB in shaping lipid composition and stress resilience in Bacteroides fragilis.

Specific Bacterial Taxa and Their Metabolite, DHPS, Linked to Alzheimers Disease, Parkinsons Disease, and Amyotrophic Lateral Sclerosis.

The paper identifies a microbial-derived metabolite, DHPS, and its associated bacterial taxa linked to three neurodegenerative diseases, suggesting a role for sulfur metabolism in disease progression.

Metabolite discovery through global annotation of untargeted metabolomics data

The paper introduces NetID, a global network optimization method for annotating untargeted metabolomics data, identifying novel metabolites in yeast and mouse datasets.
