Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...
The microbial diversity associated with sulfide structures from three
different hydrothermal vent fields was examined using phylogenetic analysis
based on the small subunit ribosomal RNA gene (16S rDNA). Samples were
collected from sites at 9°N, Guaymas Basin and the Juan de Fuca Ridge and
analyzed with denaturing gradient gel electrophoresis...
Dissolved organic matter (DOM) in the oceans is one of the largest pools of reduced carbon on Earth, comparable in size to the atmospheric CO₂ reservoir. A vast number of compounds are present in DOM, and they play important roles in all major element cycles, contribute to the storage of...
