Biodesulfurization of coal has been carried out in batch culture of single strain and mixed culture of sulfur oxidizing bacteria. The pure cultures of Thiobacillus thiooxidans and Thiobacillus ferrooxidans utilized inorganic sulfur content of Malaysian coal. The chemolithotroph bacteria were able to grow on coal and metabolize the coal's sulfur content. The batch cultures of coal with 3-5 perce...
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...
desulphurization of coal by using of thiobacillus ferrooxidans and thiobacillus thiooxidans bacteria
a new solution aiming at coal biodesulphurization has been developed based on the use of bacteria. the most frequently used species of bacteria for removal of inorganic sulphur compounds are thiobacillus ferrooxidans, thiobacillus thiooxidans and thiobacillus acidophilus. in this study the coal sample was decomposed initially and desulphurization experiments was carried out in pure and mixed cu...
In a preliminary communication (Trudinger, 1958) the separation of some soluble cytochromes of the autotrophic sulphur bacterium Thiobacillue X was briefly reported. Addition of thiosulphate to intact cells results in the rapid reduction of the cytochromes and the present work was undertaken to attempt to characterize the cytochromes and to obtain some information on the electron-transport chai...
Under anaerobic conditions and at circumneutral pH, cells of the widely distributed, obligate chemolithoautotrophic bacterium Thiobacillus denitrificans oxidatively dissolved synthetic and biogenic U(IV) oxides (uraninite) in nitrate-dependent fashion: U(IV) oxidation required the presence of nitrate and was strongly correlated with nitrate consumption. This is the first report of anaerobic U(I...
Approximately 40% of oil shale can be solubilized by the action of sulfur-oxidizing bacteria. Thiobacillus thiooxidans and Thiobacillus concretivorous are equally effective in solubilization. Continuous leaching experiments show that this process can be completed within 14 days. The growth of Thiobacillus and the production of acid were measured under several conditions. Almost all of the CaMg(...
application of sulfur as a means of lowering soil ph (even if at micro sites) is one way to increase the availability of insoluble nutrients/ effectiveness of elemental sulfur in lowering soil ph depends on the activity of sulfur oxidizing bacteria especially, thiobacillus genus/ to evaluate the possibility of partially substituting sulfur along thiobacillus inoculum for phosphorus and micronut...
In order to investigate the effects of nutritional role of maternal-plant phosphorus (P) on seed production and quality of black seed (Nigella sativa L.) in a calcareous soil, three experiments were conducted at research greenhouse of Ferdowsi University of Mashhad, Iran, in 2012 and 2013. The first and the second experiments were conducted as a complete randomized design based on factorial arr...
High concentrations of H(2)S in groundwater are commonly removed using Biological Trickling Filter (BTF) that contains high numbers of biofilm immobilized sulfur oxidizing bacteria (mainly Thiobacillus thiooxidans). BTF performance requires continuous monitoring of these bacteria at several sampling points. The Most Probable Number (MPN) technique is at the moment the method of choice to enumer...
RP1, a broad-host-range incompatibility group P1 plasmid specifying multiple drug resistances, has been transferred into the chemolithotrophic bacterium Thiobacillus neapolitanus. The ability of T. neapolitanus to receive, express, and transmit RP1-encoded antibiotic resistances was examined. The data show that this obligate chemolithotroph can accept, replicate, and express heterologous plasmi...
