a factorial experiment based on complete block design was conducted to study the interactive effects of sulfur fertilizer and thiobacillus bacteria on corn growth and root colonization with two species of mycorrhiza fungi. treatments were five levels of sulfur (s0: 0, s1: 50, s2: 100, s3: 150 and s4: 200 mg.kg-1 of dry soil), thiobacillus in two levels [no application (t0) and application of ba...

use of zinc and iron oxide are common in the desulfurization process from natural gas. in thisresearch, after determinations of the size and specifications through tem and xrd for each of the metaloxides, two different size ratios were used, 0.66 for zinc oxide and 0.142 for iron oxide. further, absorption of sulfur compounds in gas (hydrogen sulfide (h2s), carbonyl sulfide (cos), methyl mercap...

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...

In this study the role of glutathione (GSH) in sulfur mustard -induced oxidative stress and cytotoxicity, in human skin fibroblast cell line (HF2FF) was evaluated. Sulfur mustard-induced superoxide radical and hydrogen peroxide formation were evaluated by determination of superoxide dismutase and catalase activity in cell lysate. The cytotoxicity of sulfur mustard was estimated by lactate dehyd...
