Diversity in the Utilization of Different Molecular Classes of Dissolved Organic Matter by Heterotrophic Marine Bacteria

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.

Active microbial communities facilitate carbon turnover in brine pools found in the deep Southeastern Mediterranean Sea

The paper investigates microbial communities in deep-sea brine pools using metagenomics, identifying key taxa and metabolic pathways that drive carbon turnover.

Tar patties are hotspots of hydrocarbon turnover and nitrogen fixation during a nearshore pollution event in the oligotrophic southeastern Mediterranean Sea

The paper characterizes microbial communities on tar patties and control surfaces after an offshore oil spill, showing their role in hydrocarbon degradation and nitrogen fixation in the oligotrophic Mediterranean Sea.

Quantification of Aquatic Unicellular Diazotrophs by Immunolabeled Flow Cytometry

This study develops a flow cytometry-based method to quantify unicellular diazotrophs by immunolabeling nitrogenase, revealing their abundance and nitrogen fixation rates in marine and freshwater environments.

Allochthonous groundwater microorganisms affect coastal seawater microbial abundance, activity and diversity

This study shows that groundwater microbes influence coastal seawater microbial abundance, activity, and diversity through nutrient and microbial input.

An Interplay of Phytoplankton Donor Species and Transformation of Released Compounds over Time Defines Bacterial Communities Following Phytoplankton DOMp Pulses

The paper investigates how phytoplankton donor species and DOMp transformation over time shape bacterial communities in the Eastern Mediterranean.

Testing the Growth Rate and Temperature Compensation Hypotheses in Marine Bacterioplankton

The paper tests the translation-compensation and growth rate hypotheses for temperature effects on marine bacterioplankton resource allocation in lab cultures and field samples.

Phytoplankton exudates provide full nutrition to a subset of accompanying heterotrophic bacteria via carbon, nitrogen and phosphorus allocation

The paper shows that phytoplankton exudates supply both carbon and nutrients (N, P) to specific bacteria in coastal and open-ocean ecosystems of the Eastern Mediterranean.

A year in the life of the Eastern Mediterranean:Monthly dynamics of phytoplankton and bacterioplankton in an ultra-oligotrophic sea

This paper describes the annual dynamics of phytoplankton and bacterioplankton in the ultra-oligotrophic Eastern Mediterranean Sea, showing lower primary productivity compared to other oligotrophic regions but similar bacterial production.

Diversity, activity and abundance of benthic microbes in the southeastern Mediterranean Sea: A baseline for monitoring

The paper analyzes microbial diversity, activity, and abundance in the southeastern Mediterranean Sea to establish a baseline for marine biomonitoring.
