Metabolic interplay drives population cycles in a cross-feeding microbial community.
Journal Article Nature communications · October 2025 Population cycles are prevalent in ecosystems and play key roles in determining their functions. While multiple mechanisms have been theoretically shown to generate population cycles, there are limited examples of mutualisms driving self-sustained oscillat ...

Journal Article Cell systems · May 2025 The arginine dihydrolase pathway (arc operon) provides a metabolic niche by transforming arginine into metabolic byproducts. We investigate the role of the arc operon in probiotic Escherichia coli Nissle 1917 on human gut community assembly and health-rele ...
