Bacteria in Himalayan glacial ice and its relationship to dust
Bacteria Himalayan glacial ice relationship dust
2010/1/18
Concentrations and community diversity of bacteria from 50 segments of a 108.83 m ice core drilled from the East Rongbuk (ER) Glacier (28.03° N, 86.96° E, 6518 m above sea level) on the northeast slop...
Constraints on mechanisms and rates of anaerobic oxidation of methane by microbial consortia:process-based modeling of ANME-2 archaea and sulfate reducing bacteria interactions
mechanisms anaerobic oxidation methane microbial consortia ANME-2 archaea
2010/1/18
Anaerobic oxidation of methane (AOM) is the main process responsible for the removal of methane generated in Earth's marine subsurface environments. However, the biochemical mechanism of AOM remains e...
Seasonal to hour variation scales in abundance and production of total and particle-attached bacteria in the open NW Mediterranean Sea (0–1000 m)
hour variation scales abundance production particle-attached bacteria
2010/1/18
We present the vertical and temporal dynamics of total vs. particle-attached bacterial abundance and activity over a 5 week period under summer to autumn transition in NW Mediterranean Sea. At a weekl...
Heterogeneous ice nucleation activity of bacteria:new laboratory experiments at simulated cloud conditions
Heterogeneous ice nucleation activity bacteria laboratory experiments cloud conditions
2010/1/18
The ice nucleation activities of five different Pseudomonas syringae, Pseudomonas viridiflava and Erwinia herbicola bacterial species and of Snomax™ were investigated in the temperature range be...
Coupling of heterotrophic bacteria to phytoplankton bloom development at different pCO2 levels:a mesocosm study
heterotrophic bacteria phytoplankton bloom development pCO2 levels
2010/1/18
The predicted rise in anthropogenic CO2 emissions will increase CO2 concentrations and decrease seawater pH in the upper ocean. Recent studies have revealed effects of pCO2 induced changes in seawater...
High-resolution ice nucleation spectra of sea-ice bacteria:implications for cloud formation and life in frozen environments
High-resolution ice nucleation spectra sea-ice bacteria cloud formation
2010/1/15
Even though studies of Arctic ice forming particles suggest that a bacterial or viral source derived from open leads could be important for ice formation in Arctic clouds (Bigg and Leck, 2001), the ic...
Availability of phosphate for phytoplankton and bacteria and of glucose for bacteria at different pCO2 levels in a mesocosm study
Availability of phosphate phytoplankton bacteria glucose mesocosm study
2010/1/15
Availability of phosphate for phytoplankton and bacteria and of glucose for bacteria at different pCO2 levels were studied in a mesocosm experiment (PeECE III). Using nutrient-depleted SW Norwegian fj...
Competition for inorganic and organic forms of nitrogen and phosphorous between phytoplankton and bacteria during an Emiliania huxleyi spring bloom
inorganic and organic forms nitrogen phosphorous phytoplankton bacteria
2010/1/15
Using 15N and 33P, we measured the turnover of organic and inorganic nitrogen (N) and phosphorus (P) substrates, and the partitioning of N and P from these sources into two size fractions of marine os...
Culturable bacteria in Himalayan glacial ice in response to atmospheric circulation
Culturable bacteria Himalayan glacial ice atmospheric circulation
2010/1/14
Only recently has specific attention been given to culturable bacteria in Tibetan glaciers, but their relation to atmospheric circulation is less understood yet. Here we present the results of cultura...
Analyzing the trophic link between the mesopelagic microbial loop and zooplankton from observed depth profiles of bacteria and protozoa
trophic link mesopelagic microbial loop zooplankton observed depth profiles bacteria protozoa
2010/1/12
It is widely recognized that organic carbon exported to the ocean aphotic layer is significantly consumed by heterotrophic organisms such as bacteria and zooplankton in the mesopelagic layer. However,...
