The impact of microbial metabolism on marine dissolved organic matter
Kujawinski, Elizabeth B.

Microbes mediate global biogeochemical cycles through their metabolism, and all metabolic processes begin with the interaction between the microbial cell wall or membrane and the external environment. For all heterotrophs and many autotrophs, critical growth substrates and factors are present within the dilute and heterogeneous mixture of compounds that constitutes dissolved organic matter (DOM). In short, the microbe--molecule interaction is one of the fundamental reactions within the global carbon cycle. Here, I summarize recent findings from studies that examine DOM--microbe interactions from either the DOM perspective (organic geochemistry) or the microbe perspective (microbial ecology). Gaps in our knowledge are highlighted and future integrative research directions are proposed.

Molecular level characterization of methyl sugars in marine high molecular weight dissolved organic matter Panagiotopoulos, Christos; Repeta, Daniel J.; Mathieu, Laura; Rontani, Jean-Francois; Sempere, Richard (2013-03-04)Dissolved organic matter (DOM) is the largest active organic carbon reservoir in the ocean (662 Gt C), a major fraction (> 95%) of which remains chemically uncharacterized. The concentration and isolation of DOM from ...
Multiple tracers demonstrate distinct sources of dissolved organic matter to lakes of the Mackenzie Delta, western Canadian Arctic Tank, Suzanne E.; Lesack, Lance F. W.; Gareis, Jolie A. L.; Osburn, Christopher L.; Hesslein, Ray H. (Association for the Sciences of Limnology and Oceanography, 2011-07)Lakes of the Mackenzie Delta occur across a gradient that contains three clear end members: those that remain connected to river-water channels throughout the summer; those that receive only brief inputs of river water ...
