Background & Aims of the Study: Sulfur dioxide is a component of greatest concern and is used as an indicator for the larger group of gaseous sulfur oxides (SOx). Sulfur dioxide can be absorbed into your body through the nose and lungs, its reaction with the moisture in the nose and nasal cavity, and entering the circulatory system directly through the airways. The aim of this study is ...

the 24 maltiparous holstein dairy cows were allocated in a completely randomized design to study the effects of different level and source of sulfur supplement in close-up diets on blood metabolites, colostrums composition and liver performance. the mean body weight of the cows was 687.9 kg and the mean days until expected calving date was 21.8 d. the first treatment (t1) has contained 0.21% su...

The present study aimed to identify the abilities of δ-aminolevulinic acid (ALA) producing purple non-sulfur bacteria (PNSB), Luteovulum sphaeroides W22 and W47, reduce Na+ concentration, ameliorate soil fertility, nutrients uptake, growth yield rice on salt-contaminated soil. A two-factor experiment was conducted following a completely randomized block design. factors were frequency applying s...

Why is it that different organisms do so many different things with sulfur?  Sulfur exists in many different oxidation states  Reduced sulfur is required for many biomolecules  Sulfur forms can serve as an electron sources or as electron acceptors  Oxidation states of sulfur  Sulfur assimilation in bacteria and yeasts  Sulfur-containing biomolecules  Sulfide Oxidation  Sulfate Reduction...

in order to study the effect of different levels of nitrogen and sulfur fertilizers on yield, yield components, content of some elements, qualitative and quantitative traits of spring safflower (serin cv.) an experiment was conducted at agriculture and natural resource research station of ardabil in 2008. this experiment was carried out in factorial experiment in completely randomized block des...

Homocysteine also known as the H-factor, is a naturally occurring amino acid and is a by-product of methionine metabolism in the body. It is a common amino acid (one of the building blocks that make up proteins) found in the blood and is acquired mostly from eating meat. In 1969, a connection between homocysteine (a sulfur-containing amino acid) and cardiovascular disease was proposed when it w...

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...

Homocysteine is a sulfur-containing aminoacid produced during metabolism of methionine. Since 1969 the relationship between altered homocysteine metabolism and both coronary and peripheral atherotrombosis is known; in recent years experimental evidences have shown that elevated plasma levels of homocysteine are associated with an increased risk of atherosclerosis and cardiovascular ischemic eve...

This study evaluates the recovery of heavy metals employing a spent catalyst from the hydrodesulfurization (HDS) of diesel, with no chemical, thermal or physical pretreatment, using the bacterial strain Acidithiobacillus thiooxidans FG-01. Direct and indirect bioleaching tests were carried out in Erlenmeyer flasks (500 mL). The influence of the pulp density and supplementation with elemental su...
