Human Gut Microbiota of Healthy Individuals Show Resilience to Acute Aflatoxin B1 Exposure Despite Solvent-Driven Community Shifts

Hannah Glesener, Nicole Dorn, Qiwen Cheng…·Rosa Krajmalnik‐Brown

This study shows that acute aflatoxin B1 exposure does not significantly alter human gut microbiota composition or function, with observed changes attributed to solvent effects rather than direct toxin impact.

Reconsidering the Use of Dimethyl Sulfoxide for Xenobiotic-Gut Microbiota Interaction Studies

Qiwen Cheng, Hannah Glesener, Aurely Sanchez Carreon…·Rosa Krajmalnik‐Brown

This study shows that DMSO significantly alters gut microbiota metabolism and enriches Desulfovibrio desulfuricans, overshadowing xenobiotic effects.
