Isolation of aerobic anoxygenic photosynthetic bacteria from black smoker plume waters of the juan de fuca ridge in the pacific ocean.
نویسندگان
چکیده
A strain of the aerobic anoxygenic photosynthetic bacteria was isolated from a deep-ocean hydrothermal vent plume environment. The in vivo absorption spectra of cells indicate the presence of bacteriochlorophyll a incorporated into light-harvesting complex I and a reaction center. The general morphological and physiological characteristics of this new isolate are described.

Summer community structure of aerobic anoxygenic phototrophic bacteria in the western Arctic Ocean.
Aerobic anoxygenic phototrophic (AAP) bacteria are found in a range of aquatic and terrestrial environments, potentially playing unique roles in biogeochemical cycles. Although known to occur in the Arctic Ocean, their ecology and the factors that govern their community structure and distribution in this extreme environment are poorly understood. Here, we examined summer AAP abundance and diver...
متن کاملDistribution of planktonic aerobic anoxygenic photoheterotrophic bacteria in the northwest Atlantic
Aerobic anoxygenic photoheterotrophic (AAP) bacteria can use both dissolved organic matter and light for energy production, but their photosynthesis does not produce oxygen. We measured AAP bacterial cell and bacteriochlorophyll distributions in the northwest Atlantic, from the coast of the Gulf of Maine to the Sargasso Sea, in October 2001 and March 2002. The abundance of AAPs ranged from 7 3 ...
متن کاملIsolation of tellurite- and selenite-resistant bacteria from hydrothermal vents of the Juan de Fuca Ridge in the Pacific Ocean.
Deep-ocean hydrothermal-vent environments are rich in heavy metals and metalloids and present excellent sites for the isolation of metal-resistant microorganisms. Both metalloid-oxide-resistant and metalloid-oxide-reducing bacteria were found. Tellurite- and selenite-reducing strains were isolated in high numbers from ocean water near hydrothermal vents, bacterial films, and sulfide-rich rocks....
متن کاملHigh abundances of aerobic anoxygenic photosynthetic bacteria in the South Pacific Ocean.
Little is known about the abundance, distribution, and ecology of aerobic anoxygenic phototrophic (AAP) bacteria, particularly in oligotrophic environments, which represent 60% of the ocean. We investigated the abundance of AAP bacteria across the South Pacific Ocean, including the center of the gyre, the most oligotrophic water body of the world ocean. AAP bacteria, Prochlorococcus, and total ...
متن کاملEntrainment and bending in a major hydrothermal plume, Main Endeavour Field, Juan de Fuca Ridge
[1] We measure expansion rate and bending in a 23-hour time series of acoustic images of the lower 25 m section of a buoyant hydrothermal plume rising from Grotto vent in the Main Endeavour Field, Juan de Fuca Ridge. We then calculate entrainment coefficient, the constant of proportionality relating mean inflow velocity at the plume edge to maximum mean upward velocity within the plume. The plu...
