Marine Bacteria Alteromonas spp. Require UDP-glucose-4-epimerase for Aggregation and Production of Sticky Exopolymer

This study shows that UDP-glucose-4-epimerase is required for aggregation and exopolymer production in marine bacteria Alteromonas spp., highlighting their role in particulate organic matter aggregation.

Spatial and Temporal Resolution of Cyanobacterial Bloom Chemistry Reveals an Open-Ocean Trichodesmium thiebautii as a Talented Producer of Specialized Metabolites

The paper identifies a consistent specialized metabolome in Trichodesmium thiebautii blooms and isolates a new macrocyclic compound, suggesting potential ecological roles for these metabolites.

Nutrient colimitation is a quantitative, dynamic property of microbial populations

This study quantifies nutrient colimitation in microbial populations, showing it occurs in lab conditions and nature, with different effects on growth rate and yield.

Effects of interspecies interactions on marine community ecosystem function

This study shows that interactions between microbial species affect chitin degradation rates through changes in chitinase expression, challenging the idea of unidirectional trophic cascades in microbial communities.

Microbial population dynamics decouple growth response from environmental nutrient concentration

The paper examines how microbial population dynamics affect the adaptation of half-saturation concentrations in growth response models, showing that bottlenecks and dilutions lead to different evolutionary outcomes.
