Novel connections between B-vitamins and microbial communities along biogeochemical gradients in a large temperate estuary

The paper quantifies B-vitamins and microbial communities in a temperate estuary, finding key B-vitamins influence plankton composition and revealing spatial and temporal dynamics.

Predatory bacteria impact C. elegans life-history traits by modulating microbiota community dynamics and thereby vitamin B12 availability

This study shows predatory bacteria alter C. elegans microbiota, increasing vitamin B12 availability, which extends lifespan by suppressing a detoxification pathway.

Chemosynthetic Symbioses as Hidden Hubs of DMSP and Organosulfur Cycling in Marine Sediments

This study identifies DMSP and DMS cycling as integral to the metabolism of gutless oligochaete symbioses, revealing widespread organosulfur metabolism across species.

Seasonal patterns in b-vitamins and cobalamin co-limitation in the Northwest Atlantic

This study measures b-vitamins and cobalamin in the Northwest Atlantic over 5 years, showing seasonal differences in their concentrations and their impact on phytoplankton growth.

Production of the cobalamin lower ligand, α-ribazole, by a diatom under cobalamin-deplete conditions

This paper shows a diatom produces the cobalamin lower ligand, α-ribazole, under cobalamin-deplete conditions, suggesting eukaryotic contributions to cobalamin remodeling in marine ecosystems.
