Genetically Programmed Control of Overflow Metabolism
Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1624-1633, June 2026.ABSTRACT Overflow metabolism is a highly undesirable phenomenon that occurs in virtually all cell factories. Although several schemes have been applied to avoid overflow metabolism, this problem remains far from being solved. In this study, a genetic sensor for detecting overflow metabolism was designed, and its substrate specificity and reversibility ...

Biotechnology and Bioengineering, Volume 123, Issue 6, Page 1648-1660, June 2026.Conventional bulk media are often unsuitable for single‐cell cultivation and analysis because they provide excess nutrients or lack essential components. Redesigning the medium allows for controlled, defined growth, enabling the development of a robust minimal medium that supports quantitative and reproducible single‐cell analysis across different ...

Historical Contingency Drives Freshwater Microbial Community Assembly Across Successional Time
Ecology and Evolution, Volume 16, Issue 6, June 2026.Using a 60‐day full‐factorial reciprocal transplant microcosm experiment, we quantified the relative contributions of historical contingency, environmental selection, and dispersal limitation to freshwater bacterial community assembly. We show a pronounced temporal shift from early dispersal‐driven assembly to late‐stage dominance of historical ...

Persistence Criteria for a Chemostat with Variable Nutrient Input [PDF]
, 2001 The standard single-species chemostat model is modified to include a variable nutrient input which is assumed only to be nonnegative, bounded, and continuous.

Niche Overlap Is Not Enough: Same Overlap, Contrasting Fluctuations
Ecology Letters, Volume 29, Issue 6, June 2026.Niche overlap summarizes competitive coupling at equilibrium, but it can fail to predict out‐of‐equilibrium dynamics such as temporal abundance correlations. We show that communities with identical niche overlap can exhibit opposite correlation patterns, and that a yield‐depletion mismatch (depletion dissimilarity minus yield dissimilarity ...

Microbial interactions as modular: Implications for ecosystem dynamics and evolution
Ecological Monographs, Volume 96, Issue 2, May 2026.Abstract Microbial communities contribute to numerous processes that profoundly impact planetary and human health. They therefore hold potential for addressing many of today's pressing global challenges. Microbial ecosystems have been studied at many levels, ranging from the molecular processes of individual cells to the emergent properties and ...

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains
Oikos, Volume 2026, Issue 5, May 2026.Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.
