Global biogeography of SAR11 marine bacteria
The ubiquitous SAR11 bacterial clade is the most abundant type of organism in the world's oceans, but the reasons for its success are not fully elucidated. We analysed 128 surface marine metagenomes, including 37 new Antarctic metagenomes. The large size of the data set enabled internal transcribed spacer (ITS) regions to be obtained from the Southern polar region, enabling the first global cha...
متن کاملOne Carbon Metabolism in SAR11 Pelagic Marine Bacteria
The SAR11 Alphaproteobacteria are the most abundant heterotrophs in the oceans and are believed to play a major role in mineralizing marine dissolved organic carbon. Their genomes are among the smallest known for free-living heterotrophic cells, raising questions about how they successfully utilize complex organic matter with a limited metabolic repertoire. Here we show that conserved genes in ...
متن کاملBiogas Production by Encapsulated Methane- Producing Bacteria
Encapsulation of methane-producing bacteria was carried out with the objective of enhancing the rate of biogas production. Encapsulation with a one-step liquid-droplet-forming technique was employed for the natural membrane, resulting in spherical capsules with an average diameter and a membrane thickness of 4.3 and 0.2 mm, respectively. The capsules were made from alginate, using chitosan or C...
متن کاملPhosphate Uptake by Phosphate-Starved Euglena
Phosphate participates in an essential way in a number of cell functions, including glycolysis, oxidative phosphorylation, and nucleic acid synthesis. In almost all the cell types studied, the entry of phosphate seems to be controlled at the cell surface (1). In yeast, in which phosphate can be transported against a concentration gradient, the accumulation of phosphate depends on glycolysis and...
متن کاملBiomass production and assimilation of dissolved organic matter by SAR11 bacteria in the Northwest Atlantic Ocean.
Members of the SAR11 clade often dominate the composition of marine microbial communities, yet their contribution to biomass production and the flux of dissolved organic matter (DOM) is unclear. In addition, little is known about the specific components of the DOM pool utilized by SAR11 bacteria. To better understand the role of SAR11 bacteria in the flux of DOM, we examined the assimilation of...
