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 biodesulfurization (bds) of sulfur compounds in fossil fuels is a process to reduce sulfur dioxide emissions that cause environmental pollution. gordonia alkanivorans ripi90a is able to convert dibenzothiophene, an organic sulfur compound in petroleum, to 2-hydroxybiphenyl (2-hbp) in 4s pathway. in this study, (dbt), dsza and dszb, dbt sulfone monooxygenase, and desulfinase were respectivel...

Dewatered sludges and biosolids generated from wastewater treatment facilities are known to emit malodorous odors causing public inconvenience. The odors typically comprise of reduced organo sulfur based compounds and nitrogen containing compounds. Lime stabilization is a technique which is commonly used in the wastewater industry to produce biosolids having reduced odors that can be safely lan...

BACKGROUND The study is focused on searching for the link between acetylsalicylic acid (ASA) and sulfur metabolism. The present work aimed to investigate the effect of ASA on the level of the sulfane sulfur and non-protein thiol compounds (NPSH) in the liver and kidneys of mice. METHODS The study was conducted on female albino Swiss mice weighing approximately 20 g. The experimental group was...

Organisms must confront various environmental stresses. The liver is central to protecting against such stresses in mammals, and it has many detoxification and anti-oxidative stress functions. Radiation is a source of oxidative stress and is known to affect the liver and induce anti-oxidative responses. The detoxification enzyme rhodanese, which is also called thiosulfate sulfurtransferase (TST...

Diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS) are major oil-soluble organosulfur compounds of garlic responsible for most of its pharmacological effects. The present study investigated the influence of repeated intraperitoneally (ip) administration of DAS, DADS and DATS on the total level of sulfane sulfur, bound sulfur (S-sulfhydration) and hydrogen sulfide (H₂S...
