Due to unsuitable soil physical conditions, calcareous soils, and the existence of a huge amount of sulfur in the country, the study of sulfur effects on the soil structure and other soil properties is necessary. Therefore, the effects of different rates of sulfur including: 0, 750, 1500 and 3000 kg/ha, when accompanied by Halothiobacillus neapolitanus bacteria, on the soil properties in the co...
Lambs fed semipurified diets supplemented with DL-methionine, hydroxy analog of methionine, calcium sulfate, sodium sulfate or elemental sulfur gained faster, consumed more dry matter, and digested and retained greater weights of nitrogen and sulfur (P<.01) than lambs fed a sulfur deficient diet. Lambs fed a sulfur deficient diet had severe weight losses in 40 days and were removed from the exp...
X-ray absorption near edge structure (XANES) spectroscopy at the sulfur K-edge was applied to probe the speciation of sulfur of metabolically different sulfur-accumulating bacteria in situ. Fitting the spectra using a least-square fitting routine XANES reveals at least three different forms of sulfur in bacterial sulfur globules. Cyclooctasulfur dominates in the sulfur globules of Beggiatoa alb...
Background and aims: The emission of sulfur dioxide in air has hazardous effects on human health and environment. In this research the use of surfactants with sodium bicarbonate and limestone for the removal of sulfur dioxide was studied. Methods: A packed scrubber was used and the effect of absorbents (limestone or sodium bicarbonate), the kind and concentration of surfactants were assessed...
soil and water salinity damage and decrease canola yield. however, plant yield should be increased using effective methods. this study aimed at investigating the effect of sulfure application fertilizers on canola yield. to this end, the experiment was conducted in split plot arrangement based on randomized complete blocks design with three replications at shavoor research station in south west...
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...
Two onions (Sulfur-1 and Sulfur-4) cultivated with different sulfur applications were thermally processed to elucidate the effects of heat treatment on browning index and antioxidant activity. Sulfur-4 onion had higher sulfur content compared with the Sulfur-1 onion. After thermal processing, browning intensity was different between the two onions juices, with lower values observed for Sulfur-4...
The 0 60 "buckyball" I a prominent member of the recently discovered family of fullerene molecules, is an unusual system with exciting properties. This contribution summarizes the present state of theoretical understanding of the equilibrium structure of carbon clusters, in particular the fullerenes, the optical properties of individual fullerene molecules, superconductivity in the alkali-inter...
The interaction of sulfur mustard with aminoacids and proteins has been investigated in this study. Rats were injected with sublethal doses of sulfur mustard subcutaneously and intraperitoneally. At different time intervals, plasma and urine samples were collected. The binding affinity of sulfur mustard with urinary and plasma proteins and enzymes was studied for the first time using non-i...
BACKGROUND Acidithiobacillus caldus (A. caldus) is widely used in bio-leaching. It gains energy and electrons from oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs) for carbon dioxide fixation and growth. Genomic analyses suggest that its sulfur oxidation system involves a truncated sulfur oxidation (Sox) system (omitting SoxCD), non-Sox sulfur oxidation system simila...
