Geomicrobiological aspects of the oxidation of reduced sulfur compounds by photosynthesizing bacteria.

Simultaneous Electricity Generation and Sulfur Removal by Electrogenic Sulfate Reducing Bacteria in BES System

The modern BioElectrochemical technologies can convert the energy stored in the chemical bonds of biodegradable organic materials to renewable electrical energy through the catalytic reactions of microorganisms while treating the waste waters. The present research was conducted to evaluate the efficiency of a single-chamber Bioelectrochemical system with the carbon aerogel catalyst, as a simple...

Oxidation of reduced inorganic sulfur compounds by bacteria: emergence of a common mechanism?

Oxidation of Alcohols by Non-Sulfur Photosynthetic Bacteria.

Carbon dixoide is reduced anaerobically to cell substance and water by the hydrogen donor H%A through the agency of photosynthetic pigments with the absorption of radiant energy. Two more or less clear-cut groups ca be distinguished among the purple bacteria on the basis of their physiological characteristics. One group, the sulfur purple bacteria (family Thiorhodeae Molihch, 1907) can develop ...

1-Butyl-3-Methylimidazolium Bromide Promoted Selectively Oxidation of Sulfur Compounds by NaBrO3

1-Butyl-3-methylimidazolium bromide ([bmim]Br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by NaBrO3 in excellent yields under neutral conditions.

Using Inoculants to Obtain Proper Source of Soil

The nutrient elements uptake in many of soils, is a problem because of high pH and plenty of calcium ions in them. Some of these elements are phosphorus and microelements. It is possible to increase absorption of these nutrient elements by addition of sulfur in soil and biological oxidation. The rate of this reaction is very slow and Thiobacillus bacteria are the most important oxidators of sul...
