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...

The extracellular lipid of Thiobacillus thiooxidans is a heterogeneous mixture of phospholipid and neutral lipid, primarily free fatty acids.

abstract date palm, phoenix dactylifera, is one of the most important horticultural crops in iran. the most soils in iran, especially those cultivated with palm, are calcareous with high ph. the high ph of soil causes reduction of nutrient elements absorption. findings of researches show that application of elemental sulfur along with tiobacillus bacteria in soil, due to sulfur oxidation, reduc...

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...

the effects of inoculation of thiobacillus and the type of nitrogen fertilization (urea and ammonium sulphate fertilizers) on yield and yield components of rapeseed cultivars (okapi, slm 046 and reagent * cobra) were studied. the experiment was carried out as spilit plot factorial in randomized complete block design with 4 replications in shahrood university of technology. reagent * cobra culti...

We investigated the production and regeneration of Thiobacillus ferrooxidans spheroplasts. Regeneration frequencies of up to 90% reversion were obtained. Attempts to transform T. ferrooxidans spheroplasts with a recombinant T. ferrooxidans plasmid were unsuccessful.

Genetic transformation of Thiobacaillus thioparus auxotrophs to prototrophy was obtained at frequencies of up to 10(-2) when proliferating cell populations were exposed to chromosomal DNA from a nutritionally independent strain of the same bacterium. The rate at which transformation occurred depended on recipient growth rate and could be drastically reduced by depriving otherwise competent cell...
