The paper establishes and characterizes a marine bacterial library, identifying genetic variations, growth patterns, and methodological challenges in strain maintenance and analysis.

This study uses transcriptomics and proteomics to show that Prochlorococcus survives nitrogen limitation through a mutualistic relationship with Alteromonas, which recycles nitrogen via organic matter degradation.

The paper assesses four mechanisms of phytoplankton-bacteria interactions using models and experiments, finding two distinct modes of interaction and highlighting the need for additional mechanisms like allelopathy.

The paper shows that DOM from nitrogen-starved and virus-infected Prochlorococcus triggers different microbial responses in the Eastern Mediterranean Sea.

The paper examines how nitrogen and phosphate starvation affect cell death in 15 Prochlorococcus strains, identifying sensitivity patterns linked to DNA repair and protein quality control genes.

The paper describes a collaborative curation workshop to improve the metabolic reconstruction of Alteromonas macleodii ATCC 27126 using genomic and physiological data, identifying key metabolic pathways and gaps.

This study investigates how different molecular classes of dissolved organic matter (DOM) are utilized by heterotrophic marine bacteria in the Eastern Mediterranean Sea, revealing diverse utilization patterns among bacterial clades.
