Limited utilization of extracted dissolved organic matter by prokaryotic communities from the subtropical North Atlantic
Bercovici, Sarah K.; Arroyo, Mar C.; De Corte, Daniele; Yokokawa, Taichi; Hansell, Dennis A. (Limnology and Oceanography, 2021-05-06)The ocean contains a large reservoir of dissolved organic matter (DOM) that persists for millennia. Both the very dilute concentrations of individual DOM molecules and intrinsic recalcitrance to microbial decay imparted ... -
The detection of bacterial exometabolites in marine dissolved organic matter through ultrahigh‐resolution mass spectrometry
Bercovici, Sarah K.; Dittmar, Thorsten; Niggemann, Jutta (Limnology and Oceanography: Methods, 2022-05-05)Bacteria play a key role in sustaining the chemodiversity of marine dissolved organic matter (DOM), yet there is limited direct evidence of a major contribution of bacterial exometabolites to the DOM pool. This study tests ... -
Zooplankton‐derived dissolved organic matter composition and its bioavailability to natural prokaryotic communities
De Corte, Daniele; Varela, Marta M.; Louro, Angeles M.; Bercovici, Sarah K.; Valencia‐Vila, Joaquín; Sintes, Eva; Baltar, Federico; Rodríguez‐Ramos, Tamara; Simon, Meinhard; Bode, Antonio; Dittmar, Thorsten; Niggemann, Jutta (Limnology and Oceanography, 2022-12-02)Zooplankton grazing onphytoplankton promotes the release of particulate and dissolved organic matter (DOM) into the water column and therefore plays a key role in organic matter cycling in aquatic systems. Prokaryotes are ...
