The proteomic and transcriptomic responses to iron, sulfur, and nitrogen limitation in the abundant marine bacterium Candidatus Pelagibacter ubique

Creator:

Smith, Daniel P.

Abstract:

Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...

Genome-enabled investigation of the minimal growth requirements andphosphate metabolism for Pelagibacter marine bacteria

Creator:

Carini, Paul J.

Abstract:

Members of the SAR11 clade of heterotrophic α-proteobacteria are ubiquitous and abundant in the world's oceans where they are thought to play a pivotal role in the global carbon cycle. The first SAR11 bacterium cultivated in vitro, 'Candidatus Pelagibacter ubique' HTCC1062 (Ca. P. ubique), was isolated by dilution into sterile...
