Genomic-assisted determination of the natural nutrient requirements of the cosmopolitan marine bacterium 'Candidatus Pelagibacter ubique'

Creator:

Tripp, H. James

Abstract:

To identify factors limiting 'Candidatus Pelagibacter ubique' maximum cell density and growth rate in pure culture on seawater, the genome sequence of 'Cand. P. ubique' was analyzed, culturing experiments with organic and inorganic nutrient additions were made, and radiotracer uptake experiments were performed. The genome was sequenced, custom data mining...

Outliers: The Unusual Characteristics of Marine Carbon-Oxidizing Bacterial Cells Adapted to Oligotrophic Conditions

Creator:

Noell, Stephen E.

Abstract:

Oligotrophic bacteria are adapted to low nutrient concentrations. As most of the ocean is oligotrophic (low in nutrients), oligotrophic bacteria thrive in the ocean and make up the majority of planktonic cells. Because of this, oligotrophs are crucial to oceanic nutrient cycles. However, marine oligotrophic bacteria are dwarfed by their...
