Sulfur enhancement effects for uranium bioleaching in column reactors from a refractory uranium ore

Frontiers in Microbiology, 2023
The feasibility of sulfur enhancement for uranium bioleaching in column reactors was assessed with a designed mixed Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum ferriphilum from a refractory uranium ore.

Physiological and Mechanistic Studies of Phototrophic Fe(II) Oxidation in Purple Non-sulfur Bacteria [PDF]

, 2007
Phototrophic Fe(II)-oxidizing bacteria use electrons from ferrous iron [Fe(II)] and energy from light to drive reductive CO₂ fixation. This metabolism is thought to be ancient in origin, and plays an important role in environmental iron cycling. It has

In the Alphaproteobacterium Hyphomicrobium denitrificans SoxR Serves a Sulfane Sulfur-Responsive Repressor of Sulfur Oxidation

Antioxidants, 2023
In organisms that use reduced sulfur compounds as alternative or additional electron donors to organic compounds, transcriptional regulation of genes for enzymes involved in sulfur oxidation is needed to adjust metabolic flux to environmental conditions.

Sulfur Oxidation in the Acidophilic Autotrophic Acidithiobacillus spp.

Frontiers in Microbiology, 2019
Sulfur oxidation is an essential component of the earth’s sulfur cycle. Acidithiobacillus spp. can oxidize various reduced inorganic sulfur compounds (RISCs) with high efficiency to obtain electrons for their autotrophic growth.

Chemoautotrophic carbon fixation rates and active bacterial communities in intertidal marine sediments. [PDF]

PLoS ONE, 2014
Chemoautotrophy has been little studied in typical coastal marine sediments, but may be an important component of carbon recycling as intense anaerobic mineralization processes in these sediments lead to accumulation of high amounts of reduced compounds,

Unique Populations of Sulfur-Oxidizing Bacteria in Natural Cold Sulfur Springs in Slovakia

, 2023
Currently, there are over 200 officially registered sulfur springs in Slovakia, most of which are cold hydrogen sulfide springs with a characteristic strong odor of rotten eggs. Their typical inhabitants are filamentous sulfur-oxidizing bacteria. The aim

Ecology of Sulfur-Oxidizing Bacteria in Hot Acid Soils [PDF]

Journal of Bacteriology, 1972
Hot acid soils in Yellowstone National Park are rich in elemental sulfur and harbor extensive populations of sulfur-oxidizing bacteria. Thiobacillus thiooxidans is found at temperatures below 55 C, and at temperatures from 55 to 85 C Sulfolobus acidocaldarius is present.

Evolution and Maintenance of Mutualism between Tubeworms and Sulfur-Oxidizing Bacteria [PDF]

The American Naturalist, 2021
AbstractTubeworms and sulfur-oxidizing bacteria mutualism, an essential part of the chemosynthetic ecosystem in the deep sea, has several puzzling features. After acquiring sulfur-oxidizing bacteria from the environment, tubeworms become fully dependent on their symbiont bacteria for nutrient intake.

Sulfur-Oxidizing Symbionts without Canonical Genes for Autotrophic CO₂ Fixation

mBio, 2019
Since the discovery of symbioses between sulfur-oxidizing (thiotrophic) bacteria and invertebrates at hydrothermal vents over 40 years ago, it has been assumed that autotrophic fixation of CO2 by the symbionts drives these nutritional associations.

The effects of Mary Rose conservation treatment on iron oxidation processes and microbial communities contributing to acid production in marine archaeological timbers [PDF]

, 2014
The Tudor warship the Mary Rose has reached an important transition point in her conservation. The 19 year long process of spraying with polyethylene glycol (PEG) has been completed (April 29(th) 2013) and the hull is air drying under tightly controlled ...
