Colorless sulfur oxidizing bacteria from diverse habitats
Colorless sulfur oxidizing bacteria comprise an important part of sulfur cycle in nature and hold significant value for biotechnological applications such as, increasing soil fertility, reduction of environmental pollution by biologically oxidizing toxic sulfides present in waste waters from different industries and sewage, leaching of economically important metals from poor ores. Present artic...
متن کاملA mathematical model for electrochemically active filamentous sulfide-oxidising bacteria.
Oxygen and sulfide in ocean sediments can be consumed biologically over long spatial distances by way of filamentous bacteria in electron-conducting sheaths. To analyse observations, a mathematical model of these filamentous sulfur-oxidising bacteria was developed, including electrical conduction between reactive zones. Mechanisms include Nernst-Planck diffusion and migration of ions coupled wi...
متن کاملCompetition for sulfide among colorless and purple sulfur bacteria in cyanobacterial mats.
The vertical zonation of light, O2, H2S, pH, and sulfur bacteria was studied in two benthic cyanobacterial mats from hypersaline ponds at Guerrero Negro, Baja California, Mexico. The physical-chemical gradients were analyzed in the upper few mm at < or = 100 micrometers spatial resolution by microelectrodes and by a fiber optic microprobe. In mats, where oxygen produced by photosynthesis diff...
متن کاملCharacterization of an autotrophic sulfide-oxidizing marine Arcobacter sp. that produces filamentous sulfur.
A coastal marine sulfide-oxidizing autotrophic bacterium produces hydrophilic filamentous sulfur as a novel metabolic end product. Phylogenetic analysis placed the organism in the genus Arcobacter in the epsilon subdivision of the Proteobacteria. This motile vibrioid organism can be considered difficult to grow, preferring to grow under microaerophilic conditions in flowing systems in which a s...
متن کاملIdentification, characterization and application of sulfide- oxidizing bacteria in oil fields
The cycling of sulfur in oil field brines has focused predominantly on bacteria involved in the reduction of sulfur species to sulfides, which are detrimental to the production of these fields. However, recent interest in the addition of nitrates and nitrites to oil field brines for the remediation and control of sulfides has rekindled new interest in sulfide bio-oxidation. Addition of nitrate ...
